What is a Patent for Method for forming a semiconductor device
Search Patent for Method for forming a semiconductor device
In the production of semiconductor devices, a vast variety of materials and processes are employed. In many cases, the semiconductor device’s electrically conductive parts must be electrically isolated from any other electricallyconductive parts. The maximum allowed voltages and the life expectancy of the semiconductor device are heavily dependent on the quality and size of the electrically insulating components of the device. It is important to improve the longevity and/or the maximum allowable voltages for semiconductor devices.
A method for creating the semiconductor device is explained in various embodiments. This process involves an aniodic oxide layering on the surface of a semiconductor substrate order to create an oxide layer over the surface of the substrate. The external electrode is placed in an electrolyte. It creates an attracting electric field that attracts electrons that are oxidizing to the substrate.
Further embodiments relate to a method of forming a semiconductor device. The method comprising carrying out an anodic oxidation of a surface region of a semiconductor substrate to form an oxide layer at the surface of the semiconductorsubstrate by generating an attracting electrical field between the semiconductor substrate and an external electrode within an electrolyte to attract oxidizing ions of the electrolyte causing an oxidation of the surface region of the semiconductorsubstrate. The method also involves stimulating anodic oxidation, without the using an electric attracting field.
A method of creating an electronic device is one example. The method involves creating at least one pn junction inside the semiconductor substrate. The method also involves an aniodic oxygenation of the substrate’s surface , resulting in an oxide layer. This is accomplished by creating an attracting electric field between the substrate and the electrode within an electrolyte. This attracts the ions that are oxidizing to the electrolyte, which causes an oxidation of the substrate’s surface. A large voltage variation at the junction is because of the electric field. Additionally, the method comprises implanting dopants in the p-region or the n-region of pn-junction reducing a blocking voltage at the pn-junction to a level below the high voltage difference at the pn-junction during the anodic oxygenation.

What is a patent?
Patents are granted by the government in order to protect the invention. It grants the inventor the right to create, use and sell the idea. Society is benefited when new technology is introduced to the market. The benefits can be directly realized as people can achieve previously impossible feats, or indirectly, through the opportunities for economic growth which innovation can bring (business growth, employment).
Many drug firms and university researchers are seeking patent protection for their research and developments. Patents may cover the physical or abstract nature of a product or process or composition or method of making materials that are new to the field. Patent protection must be granted to an invention that is useful unique, innovative, and not yet known by other people in the same area.
Patents give inventors a reward for commercially successful inventions. They are an incentive to inventors to invent. Patents permit inventors and small businesses to be confident that there’s an excellent chance that they will be paid back for their time, effort, and money invested in technological development. This means they will be able to earn a living from their work.
Businesses that have the capacity to:
Protect new products and services that are innovative;
Improve the value, the popularity, and appeal of your products on the market
Differentiate your business and products from the rest;
Find out about business and technical information.
Avoid accidentally using third-party content or losing important information, original outputs, or any other creative output.
Patents transform inventor’s knowledge into a marketable asset, which opens up new opportunities for job creation through joint ventures and licensing.
Small businesses that have patent protection will be more appealing to investors in the development and commercialization of technology.
Patenting can lead to innovations and new ideas. This information can encourage creativity and could be eligible to be protected by patents.
Patents are a way to prevent untrustworthy third parties from profiting through the work of inventions.
Patent-protected technology revenues that are commercially profitable can be used to fund technological research and development (R&D) which will improve the chances of a better technology in the near future.
It is possible to use the intellectual property rights of your company to convince lenders and investors that your product has commercial potential. One patent that is powerful could lead to multiple financing opportunities. Patents as well as other IP assets are able to be used as collateral or security for debt financing. Investors are also able to view your patent assets to boost the value of their company. Forbes and other sources have stated that each patent can increase company valuation by anywhere from $500,000 to $1 Million.
Startups require a carefully-crafted business plan that leverages the IP to prove that your product or service is distinctive and superior or ingenuous. Additionally, investors will be impressed if you demonstrate that your IP rights are secured or are in progress of being secure and that they support your business strategy.
It is essential to keep an invention secret before applying for patent protection. The public divulging an invention could be detrimental to its novelty and invalidate it. Therefore, prior filing disclosures (e.g. for testing-marketing investors, investors, or for other business partners) should only be made after signing a confidentiality agreement.
There are a variety of patents. Understanding them is crucial to safeguard your invention. Utility patents are for the development of new methods and machines. Design patents cover ornamental designs. Utility patents are the most effective and shield the owner from competitors and copycats. They are typically granted to enhance or modify existing inventions. Utility patents can also be used to improve or modify existing inventions. A process patent will cover the acts or methods of performing a specific act. A chemical composition could be an amalgamation of ingredients.
What is the average length of a patent? Although utility patents are valid for 20 years from the date of their initial filing, they are able to be extended through delays in the Patent Office.
Are you interested in patenting your ideas? Patents are granted only to applicants who file first, therefore you need to file your patent application quickly. Call PatentPC today to get your patent application submitted!

How to Search for Patents
Patent searches are the initial step to getting your patent. You can do a google patent search or do a USPTO search. Patent-pending is the term for the product that has been protected by the patent application. You can use the public pair to find the patent application. When the patent office is satisfied with your application, you will be able to do an examination of the patent number to find the patent issued. Your product now has the potential to be patentable. You can also utilize the USPTO search engine. See below for details. For assistance, consult an attorney for patents. Patents granted in the United States are granted by the US trademark and patent office, or the United States patent office. The office also examines trademark applications.
Are you interested in finding other similar patents? These are the steps to follow:
1. Think of terms that describe your invention according to its function or composition.
Write down a short detailed explanation of your invention. Do not use generic terms such as “device”, “process” or “system”. Instead, consider synonyms to the terms you initially chose. Next, take note of significant technical terms as well as key words.
To help you identify the key words and concepts, try the questions below.
- What is the objective of the invention? Is it a utilitarian device or an ornamental design?
- Is inventing a method to come up with something or to perform some function? Is it a product or procedure?
- What is the purpose and composition of the invention? What is the physical makeup of the invention?
- What is the goal of the invention
- What are the technical terms and terms used to describe the nature of an invention? To help you find the correct terms, consult the technical dictionary.
2. Use these terms to find relevant Cooperative Patent Classifications on the Classification Text Search Tool. To find the best classification to your invention, scan the resulting classification’s class Schemes (class schedules). You may want to consider substituting the terms that you’re using for describing your invention, if you fail to get any results from your Classification Text Search with synonyms like the ones you used in Step 1.
3. Go through the CPC Classification Definition to determine the accuracy of the CPC classification that you’ve found. The link to a CPC classification definition is given when the classification you have selected contains a blue box with “D” on its left. CPC classification definitions can help you determine the applicable classification’s scope, so you can select the most relevant. These definitions may also include search tips or other suggestions that could be helpful for further study.
4. The Patents Full-Text Database and the Image Database allow you to search for patent documents that have the CPC classification. By focusing on the abstracts and drawings that are representative it is possible to narrow your search to the most relevant patent publications.
5. Utilize this selection of most pertinent patent documents to look at each one in depth for any the similarities to your own invention. Be sure to read the claims and specifications. Consult the applicant and patent examiner for any additional patents.
6. Find patent applications published in the public domain using the CPC classification you selected in Step 3 from the Applications Full-Text and Image Database. It is possible to use the same method of search as Step 4, narrowing your search results down to the most relevant patent applications by examining the abstract and drawings that appear on each page. Next, carefully examine the published patent applications, paying particular attention to the claims as well as additional drawings.
7. You can search for other US patent publications using keyword searching in AppFT or PatFT databases, as well as the classification search of patents that are that are not issued by the United States as described below. Also, you can utilize web search engines to search non-patent documents that describe inventions in the literature. 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.
