Publication number: 20240072203Abstract: A method for fabricating light emitting diode (LED) dice includes the steps of: providing a substrate, and forming a plurality of die sized semiconductor structures on the substrate. The method also includes the steps of providing a receiving plate having an elastomeric polymer layer, placing the substrate and the receiving plate in physical contact with an adhesive force applied by the elastomeric polymer layer, and performing a laser lift-off (LLO) process by directing a uniform laser beam through the substrate to the semiconductor layer at an interface with the substrate to lift off the semiconductor structures onto the elastomeric polymer layer. During the laser lift-off (LLO) process the elastomeric polymer layer functions as a shock absorber to reduce momentum transfer, and as an adhesive surface to hold the semiconductor structures in place on the receiving plate.Type: ApplicationFiled: November 6, 2023Publication date: February 29, 2024Applicants: SemiLEDs Corporation, SHIN-ETSU CHEMICAL CO., LTD.Inventors: Chen-Fu Chu, Shih-Kai Chan, Yi-Feng Shih, David Trung Doan, Trung Tri Doan, Yoshinori Ogawa, Kohei Otake, Kazunori Kondo, Keiji Ohori, Taichi Kitagawa, Nobuaki Matsumoto, Toshiyuki Ozai, Shuhei Ueda

Publication number: 20230316809Abstract: A computing system identifies video data capturing an expressor depicting facial behavior. The computing system analyzes the video data to determine a type of emotion exhibited by the expressor in the video data by identifying appearance changes produced by movements of facial muscles in the video data; and determining timing characteristics of the movements of the facial muscles in the video data, the timing characteristics indicating whether the facial behavior depicted by the expressor is an authentic expression or fake expression. The computing system generates a classification of the type of emotion exhibited by the expressor based on the movements of the facial muscles and the timing characteristics of the movements. The computing system outputs the classification.Type: ApplicationFiled: March 29, 2023Publication date: October 5, 2023Inventor: David Matsumoto

Patent number: 10622370Abstract: A method for fabricating a memory device with a self-aligned trap layer and rounded active region corners is disclosed. In the present invention, an STI process is performed before any of the charge-trapping and top-level layers are formed. Immediately after the STI process, the sharp corners of the active regions are exposed. Because these sharp corners are exposed at this time, they are available to be rounded through any number of known rounding techniques. Rounding the corners improves the performance characteristics of the memory device. Subsequent to the rounding process, the charge-trapping structure and other layers can be formed by a self-aligned process.Type: GrantFiled: September 25, 2015Date of Patent: April 14, 2020Assignee: Monterey Research, LLCInventors: Tim Thurgate, Shenqing Fang, Kuo-Tung Chang, Youseok Suh, Meng Ding, Hidehiko Shiraiwa, Amol Ramesh Joshi, Hapreet Sachar, David Matsumoto, Lovejeet Singh, Chih-Yuh Yang

Publication number: 20160218227Abstract: Semiconductor devices and methods of producing the devices are disclosed. The devices are formed by forming a gate structure on a substrate. The gate structure includes a charge trapping dielectric formed between the substrate and a first poly layer. A top dielectric is formed over the poly layer and a sidewall dielectric is formed on a side of the poly layer. A second poly layer is formed over the gate structure such that a portion of the second poly layer includes a vertical portion that is in contact with the sidewall dielectric and a top portion that is in contact with the top dielectric. The top portion of the second poly layer can then be removed through, for instance, planarization.Type: ApplicationFiled: February 17, 2016Publication date: July 28, 2016Inventors: Shenqing Fang, Chun CHEN, David Matsumoto, Mark T.

Publication number: 20140148009Abstract: During formation of a charge trap separation in a semiconductor device, an organic material is formed over a plurality of cells. This organic material is selectively removed in order to create a flat upper surface. An etching process is performed to remove the organic material as well as a charge trap layer formed over the plurality of cells, thereby exposing underlying first oxide layers in each of the cells and forming charge trap separation. Further, because of the selective removal step, the etch results in substantially uniform wing heights among the separated cells.Type: ApplicationFiled: November 26, 2012Publication date: May 29, 2014Applicant: Spansion LLCInventors: Angela Tai Hui, David Matsumoto, Tung-sheng Chen
