Title: Method to create air gaps
Inventor: VAN CLEEMPUT PATRICK A
IPC: H01L21/027
Filed: 2020-03-23
Abstract: An objective of the present invention is to provide materials which are able to be etched with high etching selectivity in a presence of commonly used dielectrics such as SiO_2 and SiN, and associated etching methods. Tin oxide films are used to form air gaps during semiconductor substrate processing. The tin oxide films disposed between exposed layers of other materials such as SiO_2 and SiN are selectively etched by using plasma formed in an H_2-containing process gas. The etching allows a recessed feature to be formed between surrounding materials instead of tin oxide. A third material such as SiO_2 is deposited over the recessed feature without completely filling a resulting recessed feature so as to form an air gap. In some embodiments, a method of selectively etching the tin oxide in a presence of SiO_2, SiC, SiN, SiOC, SiNO, SiCNO, or SiCN includes allowing a substrate to make contact with the plasma formed in the process gas including at least about 50 % of H_2. The etching of the tin oxide is performed without using an external bias at the substrate, and preferably performed at a temperature of less than about 100 °C.
