    摘要: A semiconductor wafer support chuck having small diameter gas distribution ports for heat transfer gas. The diameter ports inhibit plasma ignition in heat transfer gas distribution channels. The ports are less than 20 mils in diameter less than 3 mm in length. The short length of the ports facilitates fabrication of multiple ports of very small diameter. The ports communicate with a gas distribution plenum integrated into the body of the chuck beneath a wafer support surface. The plenum has radial channels and a peripheral groove for distributing heat transfer gas to the wafer support surface.

    摘要: The present invention provides a packaging semiconductor structure and method for obtaining same. The structure is comprised of at least one level of dielectric and metallurgy layers. The at least one level is comprised of a wiring metallurgy plane and a "through-via" plane of interconnecting metallurgy in association with both one and two layers of polymeric dielectric materials. The self-alignment method of fabrication of the level provides a streamlined technique wherein stringent masking and alignment requirements are relaxed, undue processing such as at least one polishing step is eliminated and a structure having adhesive integrity is fabricated.

    摘要: This document describes the fabrication and use of ceramic stabilizing layer fabricated right on the product silicon wafer to facilitate its use as a substrate for fabrication of gallium nitride films. A ceramic layer is formed and then attached to a single crystal silicon substrate to form a composite silicon substrate that has coefficient of thermal expansion comparable with GaN. The composite silicon substrates prepared by this invention are uniquely suited for use as growth substrates for crack-free gallium nitride films, benefitting from compressive stresses produced by choosing a ceramic having a desired higher coefficient thermal expansion than those of silicon and gallium nitride.
