Assignee:

Arizona Board of Regents, a coporate body organized under Arizona Law, Acting on behalf of Arizona State Univesity - Tempe AZ

International Classification:

H01L 21/311

US Classification:

438694, 438689

Abstract:

The invention provides novel methods for preparing semiconductor substrates for the growth of an ultra-thin epitaxial interfacial phase thereon. The invention additionally provides the ultra-thin epitaxial interfacial phase formed on a semiconductor substrate prepared by the methods of the invention. Epitaxiality of the interfacial phase is ensured by maintaining the cleaned semiconductor substrate in a static and inert atmosphere prior to oxidation to form the interfacial phase. Such interfacial phase are useful as capping layers and dielectric layers for semiconductor devices.

Abstract:

Substrates may be bonded according to a method comprising contacting a first bonding surface of a first substrate with a second bonding surface of a second substrate to form an assembly; and compressing the assembly in the presence of an oxidizing atmosphere under suitable conditions to form a bonding layer between the first and second surfaces, wherein the first bonding surface comprises a polarized surface layer; the second bonding surface comprises a hydrophilic surface layer; the first and second bonding surfaces are different.

Abstract:

Compositions are disclosed containing a polymeric mixture diluted into an aqueous solution, which can be usefully applied to any surface mat is hydbcphoixc to act, for example, as an aotifoggiag coating with minimal optical distortion and excellent transparency. The compositions can also be used as lubricious agents on medical implants, shunts, and surgical supplies to minimize tissue trauma, to maximize bio-compatibility, and to increase healing by enhancing better irrigation and flow in adjacent tissue.
