Publication number: 20240096998Abstract: The present disclosure describes a method for forming metallization layers that include a ruthenium metal liner and a cobalt metal fill. The method includes depositing a first dielectric on a substrate having a gate structure and source/drain (S/D) structures, forming an opening in the first dielectric to expose the S/D structures, and depositing a ruthenium metal on bottom and sidewall surfaces of the opening. The method further includes depositing a cobalt metal on the ruthenium metal to fill the opening, reflowing the cobalt metal, and planarizing the cobalt and ruthenium metals to form S/D conductive structures with a top surface coplanar with a top surface of the first dielectric.Type: ApplicationFiled: November 21, 2023Publication date: March 21, 2024Applicant: Taiwan Semiconductor Manufacturing Co., Ltd.Inventors: Shuen-Shin LIANG, Chij-chien CHI, Yi-Ying LIU, Chia-Hung CHU, Hsu-Kai CHANG, Cheng-Wei CHANG, Chein-Shun LIAO, Keng-chu LIN, KAi-Ting HUANG

Publication number: 20220031877Abstract: A cleaning and sterilizing device includes an ultrasonic cleaner, a top cover and an ultraviolet lamp. The ultrasonic cleaner has a cleaning tank for performing ultrasonic cleaning process to objects. The top cover is disposed on the opening of the cleaning tank and removable at any time. The ultraviolet lamp is installed on the bottom surface of the top cover and directly faces the cleaning tank for providing sterilization effect to the object in the cleaning tank. Therefore, the cleaning and sterilizing device of the present invention is optional to clean the object by ultrasonic cleaning or sterilize the object by irradiating it by the ultraviolet lamp, thereby attaining the objective of thorough cleaning and sterilization. Besides, the top cover with the detachable design brings convenience for adding or pouring the water in the cleaning tank, thereby increasing the usage convenience.Type: ApplicationFiled: August 3, 2020Publication date: February 3, 2022Inventor: YI-WEI LIAO
