A semiconductor package includes a substrate including an upper and a side surface, an adhesive layer disposed on the upper surface of the substrate and a stiffener comprising the horizontal portion of the adhesive layer that extends in a horizontal direction towards an exterior of the substrate in a perspective view and a vertical portion that is connected to the horizontal portion and extending vertically downwards from the horizontal portion. The vertical part is separated from the substrate’s sides with a an interval of vertical space between them. The stiffener’s outside dimension is 40 millimeters.

1. Field

This disclosure is about a package of semiconductors with a stiffener.

2. Description of Related Art

With the trend of miniaturization of semiconductor devices, many semiconductor chips and other devices may be mounted in a single package. Because of the different the thermal expansion coefficient of different components of an asemiconductor package the semiconductor package can be distorted. Thus, there is an urgent need for technology to assist in the control of warpage of the semiconductor package.

One of the embodiments of the disclosure shows a semiconductor package with stiffener.

An example embodiment of the disclosure is a semiconductor package that includes a substrate with an upper surface and sides, an adhesive layer on the edge of the substrate, and an astiffener that comprises a horizontal portion on the adhesive layer, which extends from the horizontal to the external the substrate in a plan, and a vertical part that connects to the horizontal section , and expanding vertically downwards in the horizontal portion. The vertical portion could be separated from the side surface of the substrate, with the vertical gap being extending in a vertical direction therebetween and the size of the stiffener could be at least 40 millimeters.

A semiconductor package according to with an example embodiment of the disclosure could include a substrate including an upper and side surface, a one adhesive layer disposed on the upper portion of the substrate. It also includes a stiffener called a first placed on the adhesive layer and second stiffeners that are connected to the first stiffener, placed outside the substrate, in a plan-view and extending vertically, and second layers of adhesive disposed between the stiffener that is first and the second stiffeners. One portion of each second stiffener may be spaced from the substrate’s side by a vertical gap. The width outside of each second stiffener could be greater than 40 millimeters.

An example of the disclosure is a semiconductor package that includes a substrate with an upper and sides, an adhesive layer on opposite edges of each top surface of the substrate, and a stiffener with a horizontal section positioned upon the adhesive layer, and extending horizontally from the outside of the substrate in a plan view and a vertical part that is attached to the horizontal section and running vertically downwards along with a stiffener as well as heat sink attached to the heat spreader.

What is a patent?

A patent is granted by the government to protect an invention a patent provides the inventor with the exclusive right to create, use to sell, and promote the invention? society is benefited when a brand new technology is brought to the market. The benefits can be realized directly as people are able to achieve previously unattainable feats, or indirectly via the opportunities for business growth that innovation offers (business expansion, job creation).

A lot of pharmaceutical companies and university researchers seek patent protection for their research and developments. Patents are granted for products, processes, or method of making new materials. Patent protection is granted to any invention that is valuable unique, innovative, and not already known by others in the same field.

Patents reward inventors who have commercially viable inventions. They provide a reason for inventors to invent. Patents permit entrepreneurs and inventors to know that there’s an excellent chance that they will be paid back on their time, effort, and money invested in technology development. They can make a living by their work.

Companies that are able to:

Protect your innovative products and services

Increase the value, visibility, and attractiveness of your products on the market

Stand out and differentiate yourself and your product from others.

Access business and technical expertise and information;

Beware of accidentally using content from third parties or losing valuable data, creative outputs or any other output that is creative.

Patents effectively transform the inventor’s information into a tradeable asset, which creates new opportunities for employment creation and expansion of businesses through joint ventures or licensing.

Small businesses that have patent protection will be more attractive to investors in the commercialization and development of technology.

Patents can lead to fresh ideas and innovative inventions. This information can promote creativity and could be eligible for patent protection.

Patents can be used to prevent untrustworthy third-party companies from earning through the work of inventions.

Commercially successful patent-protected technology revenues could be used to finance research and development (R&D) that will increase the chance of better technology in the near future.

Intellectual property ownership can be used to convince investors and lenders that there are genuine opportunities to market your product. A single patent could open the door for multiple financing opportunities. Patents can be used in conjunction with other IP assets as collateral or security financing. You can also show investors the patents you own to increase the value of your company. Forbes and others have stated that each patent can increase company valuation by anywhere from $500,000 to $1 million.

A well-constructed business plan is vital for new businesses. It must be founded on IP and show what your service or product is distinct. Investors will be impressed if you have IP rights are secured or are on the verge of being secured, and they agree with your business plan.

It is important to keep an invention secret until you apply for patent protection. The public disclosure of an invention before filing it is often detrimental to its originality and make it ineligible for patent protection. The filing of disclosures prior to filing, for example, for investors, test-marketing, or other business partners should be done only following the signing of a confidentiality agreement.

There are a variety of patents, and understanding these is vital to safeguard your invention. Utility patents are for the development of new methods and machines. Design patents cover ornamental designs. Utility patents are best and shield the owner from copycats and competitors. Most often the utility patent is issued for modifications or improvements on existing inventions. Utility patents can also be used to improve or modify existing inventions. A process patent could cover the acts or methods of performing a specific act. A chemical composition could be a combination of ingredients.

What is the length average of patents? Patents for utility last for 20 years after the earliest filing date, but their expirations can be extended due to patent office delays, for example.

Are you interested in finding similar patents? These are the steps:

1. Brainstorm terms to describe your invention, based on its purpose composition, use, or purpose.

Write down a brief, precise description of your invention. Avoid using generic terms such as “device”, “process” and “system”. Instead, look for synonyms to the terms you selected initially. Also, keep track of crucial technical terms, as well as key words.

To help you identify keywords and concepts, use the following questions.

  • What’s the purpose of this invention? Is it a utilitarian device or an ornamental design?
  • Is the invention a method of making something or performing some function? Is it a product or procedure?
  • What is the nature and purpose of the invention? What is the physical makeup of the invention?
  • What is the purpose of this invention?
  • What are the terms in the technical field and keywords used to describe the nature of an invention? To assist you in finding the correct terms, consult a technical dictionary.

2. These terms will allow you to search for pertinent Cooperative Patent Classifications at Classification Search Tool. If you are unable to locate the appropriate classification for your invention, scan through the classification’s class Schemas (class schedules). You may want to consider substituting the terms that you’re using to describe your invention if you don’t receive any results from your Classification Text Search with synonyms similar to the words you used in step 1.

3. Go through the CPC Classification Definition to verify the accuracy of the CPC classification you’ve located. The hyperlink to a CPC classification definition will be available if the chosen classification title contains a blue box with “D” to its left. CPC classification definitions will help identify the specific classification’s purpose which is why you can be certain to choose the one that is relevant. They may also provide some search tips or other recommendations that could be helpful for further study.

4. The Patents Full-Text Database and the Image Database allow you to find patent documents that are accompanied by the CPC classification. By focusing on the abstracts and representative drawings it is possible to narrow your search to find the most relevant patent publications.

5. Take advantage of this list of most relevant patent publications to study each one thoroughly for similarity to your idea. Be sure to read the specification and claims. There are many patents available by referring to the patent examiner and applicant.

6. Find patent applications published in the public domain using the CPC classification you selected in Step 3 of the Applications Full-Text and Image Database. The similar search strategy can be employed as Step 4. You can narrow your search results to find the most pertinent patent applications by looking over the abstracts and drawings on each page. The next step is to review the patent applications that have been published carefully, paying special attention to the claims as well as other drawings.

7. Find additional US patents by keyword searches in PatFT and AppFT databases, classification searching of non-U.S. patents as per below, and searching for non-patent literature disclosures of inventions using internet search engines. Here are some 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:
  • 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.
