2020 year H01L patent research and development hotspot panorama 01 patent application time trend
The earliest priority of patents reflects the earliest time of patent technology to some extent. The 2020 H01L semiconductor device class disclosure patent involves 161,871 Derwent patent family. The earliest priority year patents, accounting for nearly 24 months 30.14%, which is the main part of the patent disclosure in advance of the latest patents. The earliest priority earlier (2014) accounts for 14.10%, which mainly surrounds the technical layout or technology evolution layout, the number of family members, the first year of 2020 H01L Patent, the first year Distribution is shown in Figure 1.

03 Patent Application Country Distribution
(1) Patent First Priority Country and Acceptance Country Compare Analysis Patent The earliest priority Country in countries reflects the origin of a technology, Figure 3 (a) shows the earliest national priority of H01L patent / Regional distribution, can be seen from the figure that in 2020, H01L patent in mainland China is 31%, which is significantly higher than Japan (24%), the United States is ranking third, and the global proportion is 21%. South Korea ranked fourth, accounting for 13% of the world, they are the main outputs are H01L patent. The patent acceptance country reflects a market that is finally inflowed in a certain level, and Fig. 3 (b) shows the distribution of countries / regions of H01L patents. As can be seen from the figure in 2020, the United States and mainland China is the world's most important areas H01L technology markets, both global share was 31% and 30%, respectively; Japan ranked fourth, accounting for 8% .
The ratio of international application is 19%, which reflects the international layout of the applicant through the world's patent application, and pays attention to the output of technology and foreign markets. In combination, the earliest priority country and acceptance of the country / region found that in mainland China, Japan and South Korea are all higher than the proportion of the country in the country, indicating that these countries are patent technology than H01L output flows, a technical exporter; Japan's most obvious technology output, the first priority in the country / region accounting for 24% of the world, and in accepting the global proportion to 8%. The United States accounts for 21% in the earliest priority country, while the world is 31% in the world, indicating that the United States has flowed more than technical output in H01L patented technology, which belongs to the country.

(2) patented technology comparison earliest priority country / territory Table 2 shows the earliest priority patent H01L patent TOP25 main technical categories of countries / regions. The first technical priority country is in mainland China, and the main technical direction has a U12-A01A7 (LED display), U12-A01A1E (light-emitting diode processing process) and U11-C05C (manufacturing process of electrode and interconnect layer), etc. Patent Applicant For Jingdong Technology Group Co., Ltd., TCL Huaxing Optoelectronics and Siki International; the second technology priority is Japan, the main technical direction has A12-E07C (integrated circuit polymer material), L03-H05 (single Class transistor manufacturing process) and L04-C16 (semiconductor heat treatment process), etc. process), L04-C12 (process of the insulating layer and the passivation layer) and the L04-E01 (transistor-related glass, ceramics and refractories), the main patent applicant as Taiwan Semiconductor manufacturing company, IBM Corporation And application materials; South Korea as the main technical direction of technical priorities is U12-A01A1E (LED processing process), U12-A01A7 (LED display), and L04-E03 (semiconductor light emitting device), the main patent applicant is Samsung Electronics , LG Group and SK Hercules. As a technical priority, the main technical research and development directions are different from the main patent applicants. It can be seen from Table 2 that the mainstream research and development of the mainstream research and development country layout in the 2020 H01L patent is concentrated in the direction of the semiconductor device. China's mainland and China Taiwan are all under the R & D trees, Japan, the United States, and reflecting the technical output layout in Japan, Japan, the United States and reflects the development layout in the direction of semiconductor materials and process technology. See 2 shown. Table 2 2020 H01L Patent TOP25 First Priority Country / Regional Main Technical Categories
04 Patent Applicant Analysis
(1) Major Applicant Patent Number Analysis Patent Applicant analyzes the number of patents owned by H01L Patent Applicants, thereby selecting the main patent applicant, as a subsequent multi-dimensional combination analysis, evaluation, and passed the patent after cleaning The family's patent applicant analyzes that you can understand the main R & D facilities of H01L.

Number one is South Korea's Samsung, Taiwan ranked second in China's Taiwan Semiconductor Manufacturing Company, 2020 public / issued patents were involved in 8733, 5215 patent family; LG company ranked third, The number of patented family members of 2020 is 5089; China's Jingdong Technology Group Co., Ltd. and TCL Huaxing Optoelectronics are ranked fourth, fifth and 2020 patent public / announcement patents respectively related to 4524 and 3784 respectively. Item; US IBM company 2020 patent public / announcement is 2420, ranked sixth. Table 3 2020 H01L Patent TOP52 Patent Applicant Rankings
(2) Main Patent Applicants Technical Comparison Major Patent Applicant's technical comparison analysis is a comparison analysis of the main patent applicants' investment technology, dialysis of the technical development strategy of various patent applicants. Figure 4 shows the main technical comparison of H01L TOP52-bit patent applicants. Through comparative analysis, it can be seen in H01L patents disclosed in 2020, Samsung and LG companies have more layouts in the U12-A01A1E (LED processing process), and the patents are 2028 items and 1775, respectively, and their technology The direction is wide and the direction is considerable.
BOE Technology Co. layout U12-A01A7 (light emitting diode display) and U12-A01A1E (light emitting diode process) layout direction more direction larger number of patents were 1812 and 1651. Taiwan Semiconductor Manufacturing Co. TCL Huaxing power Research protrude U12-A01A1E (LED processing) and U12-A01A7 (light emitting diode display) direction, respectively patents 1448 and 1420.
