IPC: H01L21/768
Filed: 1999-12-24
Abstract: PROBLEM TO BE SOLVED: To prevent absorption of moisture by treating the damaged surface of a low dielectric constant organic oxide silicon insulating layer in an integrated circuit structure. SOLUTION: This process includes a process for treating a damaged surface 16 of a low dielectric constant organic oxide silicon insulating layer 10 in a semiconductor substrate 2, having a low dielectric constant organic oxide silicon insulating layer 10, a protective capping layer 30, and an opening 12 etched in the low dielectric constant organic oxide silicon insulating layer 10 through a resist mask by using hydrogen plasma. In this treatment using the hydrogen plasma, silicon atoms having dangling bond and hydrogen in the damaged surfaced 16 of the low dielectric constant organic oxide silicon layer 10 are connected and replaced with organic materials cut from such silicon atoms in the damaged surface 16.  Thus, blocking takes effect for absorption of moisture due to the connection of the silicon dangling bond with moisture in the damaged surface 16 of the low dielectric constant organic oxide silicon insulating layer 10.
