Publication number: 20240136226Abstract: 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: ApplicationFiled: January 2, 2024Publication date: April 25, 2024Inventors: Li-Wei CHU, Ying-Chi SU, Yu-Kai CHEN, Wei-Yip LOH, Hung-Hsu CHEN, Chih-Wei CHANG, Ming-Hsing TSAI
