Patent number: 6558755Abstract: Low dielectric constant films with improved elastic modulus. The method of making such coatings involves providing a porous network coating produced from a resin containing at least 2 Si—H groups and plasma curing the coating to convert the coating into porous silica. Plasma curing of the network coating yields a coating with improved modulus, but with a higher dielectric constant. The costing is plasma cured for between about 15 and about 120 seconds at a temperature less than or about 350° C. The plasma cured coating can optionally be annealed. Rapid thermal processing (RTP) of the plasma cured coating reduces the dielectric constant of the coating while maintaining an improved elastic modulus as compared to the plasma cured porous network coating. The annealing temperature is typically loss than or about 475° C., and the annealing time is typically no more than or about 180 seconds. The annealed, plasma cured coating has a dielectric constant in the range of from about 1.1 to about 2.Type: GrantFiled: March 19, 2001Date of Patent: May 6, 2003Assignees: Dow Corning Corporation, Axcelis Technologies, Inc.Inventors: Ivan L.

Patent number: 6558802Abstract: A hybrid silicon-on-silicon substrate. A thin film (2101) of single-crystal silicon is bonded to a target wafer (46). A high-quality bond is formed between the thin film and the target wafer during a high-temperature annealing process. It is believed that the high-temperature annealing process forms covalent bonds between the layers at the interface (2305). The resulting hybrid wafer is suitable for use in integrated circuit manufacturing processes, similar to wafers with an epitaxial layer.Type: GrantFiled: February 29, 2000Date of Patent: May 6, 2003Assignee: Silicon Genesis CorporationInventors: Francois J.
