These creative concepts are related to patterns for integrated circuits. They also include methods of examining the pattern.
Design rules, contact areas and critical dimensions, among other physical characteristics of semiconductor devices, have continuously been reduced as the degree of integration of integrated circuits fabricated using semiconductors has improved.Consequently, electronic circuits formed on substrates have become more complicated and circuit packing density of integrated circuits in substrates has gradually increased. The high circuit packing density of integrated circuits requires highoperational precision during processing/fabrication of circuit units. Accordingly, there is a requirement for more advanced detection technologies to detect problems in electronic circuits.
Embodiments are intended to create a pattern of integrated circuits and an approach to inspecting the design.
The inventive concepts embody the design of a pattern that comprises a first floating and second floating conductive lines as well as an conductive and grounded line in between. The first floating conductive line, the second conductive line floating in the water, and the grounded conductive line are separated into a main pad region as well as a number of subregions, a plurality of sub-pad regions, and an area of ground. The main pad region is situated in the first region of the design. The second end of the design includes the ground area. The plurality of subregions and the plurality of sub-pad regions are positioned between the mainpad region and the ground.
Examples of the inventive ideas further provide a pattern design comprising a first comb line and an additional comb line as well as a serpentine line placed between the first comb line and the second comb line. The first comb line has a horizontal firstmain line and a plurality perpendicular first branch lines. The second comb line includes a second main line extending horizontally and a plurality of second branch lines extendingperpendicularly from the second main line. The serpentine line connects the numerous first branch lines and a number of second branch lines. It is the shape of a serpentine. The first comb line includes a first main pad disposed at the beginning of the main line, and a multitude of first sub-pads, each at the ends of different single branch lines derived from the numerous first branch lines. The second comb line has two mainpads at the first end portion of the second line, and a plurality second sub-pads at the ends of different single branch lines. The serpentine line has an additional mainpad located at the beginning of the serpentine and third sub-pads that are located between the plurality and the second sub-pad.
Implementations of the inventive ideas are further able to provide a defect inspection method of a pattern design that is used with an electronic beam inspection apparatus comprising the controller. The method for defect inspection includes scanning the controller amain pad region formed in the first portion of a design pattern by using a particle beam and creating main pad information; scanning by the controller a first sub-pad region that is formed at the first end part of a first subregion of the pattern design using the particle beam, and generating first sub-pad information and determining by the controller, the status of the pattern using the primary pad information and the information from the first sub-pad.Click here to view the patent on USPTO website.

What is a patent?
A patent is granted by the government to protect the invention. The patent grants the inventor the sole rights to create, utilize and sell the idea. Society gains when new technologies are introduced to the market. These benefits may be realized directly when people can accomplish feats previously unattainable as well as indirectly through the opportunities for economic growth which innovation can bring (business growth, employment).
Patent protection is sought by many pharmaceutical companies and university researchers for their work in research and development. Patents may cover an abstract or physical product or process, or a method or composition of materials new to the area. Patent protection must be granted to any invention that is valuable or novel and is not previously known to others in the same field.
Patents are awarded to inventors who have commercially successful inventions. They are an incentive to inventors to invent. Patents allow inventors and small businesses to know that there is the possibility that they’ll be paid back for their efforts, time and money spent on technology development. They could earn a decent income by their work.
Patents are a crucial part of businesses with the ability to:
Create and protect the latest products and services;
Improve the visibility and the value of your product’s presence on the market
Stand out and differentiate yourself and your product from others.
Get technical and business information.
Avoid the risk of using proprietary third-party content, or losing valuable data, original outputs, or any other innovative output.
Patents transform inventor’s knowledge into an asset that can be sold, which creates new opportunities for job creation through licensing and joint ventures.
Investors in the commercialization and development of technology may find small-scale businesses that have patent protection appealing.
Patenting may lead to innovative ideas and inventions. The information you create may be protected under patents.
Patents can be used to prevent untrustworthy third parties from making money from the invention’s efforts.
Patent-protected technology revenues that are commercially viable can be used to fund technology-related research and development (R&D) that will improve the chances of better technology in future.
It is possible to use intellectual property ownership to convince lenders and investors that your product has commercial value. A single patent could open the door for multiple financing opportunities. Patents and other IP assets are able to be used as collateral or security for financing debt. Investors can also see your patent assets to increase their company valuation. Forbes and other publications have noted that each patent could increase the value of your company by as much as $500,000 to $1 million.
A well-crafted business plan is essential for new businesses. It must be based on IP and show the way your product or service is distinctive. In addition, investors will be impressed if you can prove that your IP rights are secured or are in the process of becoming secure and that they are in line with your business strategy.
It is crucial to keep an invention hidden until you submit to protect it with patents. The public disclosure of an invention can often damage its novelty and invalidate it. Thus, disclosures that are filed prior to filing (e.g. for test-marketing investors, test-marketing, or for other business partners) should only be made upon signing a confidentiality contract.
There are many kinds of patents. Knowing the different types of patents is vital to protect your invention. Utility patents cover the development of new methods and machines. Design patents cover ornamental designs. Patents for utility are the most effective as they protect the proprietor from copycats and other competition. Utility patents are often issued to improve or modify existing inventions. Utility patents also cover enhancements and modifications in existing inventions. For instance, a procedure patent covers acts or methods of doing one specific thing, whereas chemical compositions will comprise the combination of ingredients.
How long will a patent last? Utility patents last 20 years from the initial filing dates, but their expiration dates can be extended due to delays at the patent office such as.

How to Search for Patents
A patent search is the first step in obtaining your patent. You can do a google patent search or do a USPTO search. Patent-pending is the name used to describe the product protected by the patent application. It is possible to search for the public pair to locate the patent application. Once the patent office approves the application, you can conduct a patent number search to locate the issued patent, and your product has been granted patent. Alongside the USPTO search engine, you can also utilize other search engines, such as espacenet, as detailed below. You can get help from a patent lawyer. In the US patents are granted by the US patent and trademark office, or the United States patent and trademark office, which also examines trademark applications.
Are you interested in similar patents? These are the steps to follow:
1. Create a list of terms to describe your invention, based on its purpose, composition, and use.
Write down a brief, but precise description of the invention. Don’t use generic terms like “device”, “process,” or “system”. Instead, look for synonyms to the terms you selected initially. Then, take note of important technical terms as well as keywords.
To help you find keywords and concepts, use the questions below.
- What is the objective of the invention Is it a utilitarian device or an ornamental design?
- Invention is a method to make something or carry out some function? Does it constitute a product?
- What is the composition and function of the invention? What is the physical makeup of the invention?
- What is the purpose of this invention?
- What are the technical terms and keywords used to describe an invention’s nature? A technical dictionary will help you find the appropriate terms.
2. These terms will allow you to find pertinent Cooperative Patent Classifications using the Classification Search Tool. If you are unable to find the right classification to describe your invention, look through the class Schemas (class schedules). Consider substituting the words you use to describe your invention if you don’t get any results from your Classification Text Search with synonyms like the ones you used in Step 1.
3. Review 3. Go over the CPC Classification Definition to verify the accuracy of the CPC classification you’ve discovered. The hyperlink to the CPC classification definition is available when the classification you have selected is a blue square with a “D” to the left. CPC classification definitions will aid you in determining the classification’s scope of application so that you can choose the one that is most appropriate. The definitions could also contain some search tips or other recommendations that can be useful for further investigation.
4. The Patents Full-Text Database and the Image Database allow you to search for patent documents that have the CPC classification. You can search and narrow down the most relevant patent publications having a focus on the abstract and representative drawings.
5. This selection of patent publication is the most appropriate to check for similarity to your invention. Be sure to read the specifications and claims. There are many patents available by consulting the patent examiner as well as the applicant.
6. You can find patent applications published in the public domain that fit the CPC classification you selected in Step 3. You can apply the same search strategy as Step 4, narrowing your results to the most pertinent patent application by looking at the abstract as well as the drawings that appear on each page. Next, carefully examine the patent applications published with particular attention paid to the claims as well as additional drawings.
7. You can find additional US patent publications using keyword searching in AppFT or PatFT databases, and also search for patents classified as that are not issued by the United States according to below. You can also make use of search engines on the internet to search non-patent literature disclosures about inventions. Here are a few examples:
- Add keywords to your search. Keyword searches may turn up documents that are not well-categorized or have missed classifications during Step 2. For example, US patent examiners often supplement their classification searches with keyword searches. Think about the use of technical engineering terminology rather than everyday words.
- Search for foreign patents using the CPC classification. Then, re-run the search using international patent office search engines such as Espacenet, the European Patent Office’s worldwide patent publication database of over 130 million patent publications. Other national databases include:
- European Patent Office (EPO) provides esp@cenet to access a network of Europe’s patent databases with access to machine translation of European patents.
- Japan Patent Office (JPO) – with access to machine translations of Japanese patents.
- World Intellectual Property Organization (WIPO) offers PATENTSCOPE with a full-text search of published international patent applications and machine translations for some documents, as well as a list of international patent databases.
- Korean Intellectual Property Rights Information Service (KIPRIS)
- State Intellectual Property Office (SIPO) with machine translation of Chinese patents.
- Other International Intellectual Property Offices with online patent databases include Australia, Canada, Denmark, Finland, France, Germany, Great Britain, India, Israel, Netherlands, Norway, Sweden, Switzerland, and Taiwan.
- Search non-patent literature. Inventions can be made public in many non-patent publications. It is recommended that you search journals, books, websites, technical catalogs, conference proceedings, and other print and electronic publications.
To review your search, you can hire a registered patent attorney to assist. A preliminary search will help one better prepare to talk about their invention and other related inventions with a professional patent attorney. In addition, the attorney will not spend too much time or money on patenting basics.
