Publication number: 20240105496Abstract: The present invention provides a substrate supporting apparatus having a spin chuck and a plurality of locating pins. The spin chuck configured to support and rotate a substrate has a supporting surface. The locating pins are disposed at the periphery of the supporting surface for limiting the substrate horizontal displacement. The supporting surface defines a first annular region.

Publication number: 20230290637Abstract: Implantation mask formation techniques described herein include increasing an initial aspect ratio of a pattern in an implantation mask by non-lithography techniques, which may include forming a resist hardening layer on the implantation mask. The pattern may be formed by photolithography techniques to the initial aspect ratio that reduces or minimizes the likelihood of pattern collapse during formation of the pattern. Then, the resist hardening layer is formed on the implantation mask to increase the height of the pattern and reduce the width of the pattern, which increases the aspect ratio between the height of the openings or trenches and the width of the openings or trenches of the pattern. In this way, the pattern in the implantation mask may be formed to an ultra-high aspect ratio in a manner that reduces or minimizes the likelihood of pattern collapse during formation of the pattern.Type: ApplicationFiled: May 12, 2023Publication date: September 14, 2023Inventors: Wei-Chao CHIU, Yong-Jin LIOU, Yu-Wen CHEN, Chun-Wei CHANG, Ching-Sen KUO, Feng-Jia SHIU

Publication number: 20230248545Abstract: A below-elbow prosthetic arm assembly includes a hand; an arm connected to the hand; a cylinder connected to the arm; and a string connected to the rear end of the cylinder. To start using the prosthetic arm, the user's amputated upper limb is enclosed by the cylinder and tied thereto with a string. The below-elbow prosthetic arm assembly further includes an expansion kit adapted to meet the user's needs in daily lives, learning and sports. The expansion kit is directly fitted to the hand. Function expansion is achieved without removing the hand. Therefore, the below-elbow prosthetic arm exhibits enhanced ease of use and minimizes the user's financial burdens which might otherwise arise from ordering customized prosthetic arms for use in different activities.Type: ApplicationFiled: August 22, 2022Publication date: August 10, 2023Inventors: YANG-KUN OU, CHIA-HSUAN LIAO, HSUAN-YEN LEE, KAI-JUNG PENG, FENG-JIA ZHENG, WEI MING KOK, YU-KUAN MO
