Patent number: 11915976Abstract: An ammonium fluoride gas may be used to form a protection layer for one or more interlayer dielectric layers, one or more insulating caps, and/or one or more source/drain regions of a semiconductor device during a pre-clean etch process. The protection layer can be formed through an oversupply of nitrogen trifluoride during the pre-clean etch process. The oversupply of nitrogen trifluoride causes an increased formation of ammonium fluoride, which coats the interlayer dielectric layer(s), the insulating cap(s), and/or the source/drain region(s) with a thick protection layer. The protection layer protects the interlayer dielectric layer(s), the insulating cap(s), and/or the source/drain region(s) during the pre-clean process from being etched by fluorine ions formed during the pre-clean process.Type: GrantFiled: June 27, 2022Date of Patent: February 27, 2024Assignee: Taiwan Semiconductor Manufacturing Company, Ltd.Inventors: Li-Wei Chu, Ying-Chi Su, Yu-Kai Chen, Wei-Yip Loh, Hung-Hsu Chen, Chih-Wei Chang, Ming-Hsing Tsai
