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: 20220241449Abstract: Closure mechanisms for closing and sealing sterilization containers and indicators for indicating the seal integrity sterilization containers are provided. For example, a container closure mechanism may be configured to distribute a closure force along a gasket to seal a container lid to a container body. Further, a seal indicator may visibly indicate at the container exterior whether the container is sufficiently sealed to prevent an ingress of contaminants into the container. If the container is sufficiently sealed, the seal indicator is a first state, and if the sterilization container is not sufficiently sealed, the seal indicator is in a second state. Thus, the seal indicator undergoes a state change when the sterilization container transitions from unsealed to sealed or from sealed to unsealed, such that a user can ascertain whether the container is properly sealed to maintain sterility or whether the seal and sterility of the container have been compromised.Type: ApplicationFiled: April 21, 2022Publication date: August 4, 2022Inventors: Brian E. Lin, Joseph D. Hurdle, Sharon Shuh-Shin Chang, Anthony Stephen Spencer, Prasad Shrikrishna Potnis
