Publication number: 20240079315Abstract: Improved control of via anchor profiles in metals at a contact layer can be achieved by slowing down an anchor etching process and by introducing a passivation operation. By first passivating a metallic surface, etchants can be prevented from dispersing along grain boundaries, thereby distorting the shape of the via anchor. An iterative scheme that involves multiple cycles of alternating passivation and etching operations can control the formation of optimal via anchor profiles. When a desirable anchor shape is achieved, the anchor maintains structural integrity of the vias, thereby improving reliability of the interconnect structure.Type: ApplicationFiled: September 1, 2022Publication date: March 7, 2024Applicant: Taiwan Semiconductor Manufacturing Co., Ltd.Inventors: Chi-Shin WANG, Yu-Hsiang Wang, Wei-Ting Chang, Fan-Yi Hsu

Publication number: 20230021342Abstract: Methods, apparatus and systems for enhanced wireless monitoring of vital signs are described. In one example, a described system comprises: a transmitter configured to transmit a wireless signal through a wireless channel of a venue; a receiver configured to receive the wireless signal through the wireless channel; and a processor. The received wireless signal differs from the transmitted wireless signal due to the wireless channel that is impacted by a periodic motion of a vital sign of an object in the venue. The processor is configured for: obtaining a time series of channel information (CI) of the wireless channel based on the received wireless signal, computing a two dimensional (2D) decomposition of the time series of CI (TSCI), enhancing the 2D decomposition, and monitoring the periodic motion of the vital sign based on the enhanced 2D decomposition.Type: ApplicationFiled: October 4, 2022Publication date: January 26, 2023Inventors: Beibei Wang, Sakila Sandeepani Jayaweera Samaranayake Arachchige Dona, Xiaolu Zeng, Wei-Hsiang Wang, K.
