摘要： In a semiconductor device, laser energy is used to selectively heat various SiO.sub.2 and/or GeO.sub.2 based materials to elevated temperatures while maintaining the active device region and electrical interconnects at relatively low temperatures, to for example, induce densification and/or flow of the SiO.sub.2 and/or GeO.sub.2 based material to round off sharp edges and stops, without damaging or affecting the active region and electrical interconnects.

摘要： A process is disclosed for forming a planarized or smooth surface binary glass insulating film comprised of germanium dioxide and silicon dioxide by a spin-on process. The resulting structure has a film thickness uniformity which varies less than 5% over the surface of the wafer. The structure is formed by mixing a predetermined solution of TEOS and TEOG in a lower alcohol or ketone solvent and catalyzing by the addition of sufficient acid to raise the pH to 1.5 to 2.0 to favor gel formation. The resultant solution is then spun on at an RPM selected to give the desired film thickness for a given solids content of the solution.

摘要： A method of introducing a controlled flow of vapor from a high pressure sublimation chamber into a low pressure vapor deposition reactor, said vapor being derived from solid source material preferably, but not necessarily, having a vapor pressure above about one (1) Torr at a temperature not exceeding about 350.degree. C. The method comprises controllably heating the source material to a temperature sufficient to produce vapor therefrom at a desired pressure, and then controllably transferring the vapor through vapor transmission means to the vapor deposition reactor. During such transfer, the transmission means is maintained at a temperature sufficient to prevent condensation of the vapor therein during transfer. The vapor is delivered to the reactor in a pure state and is not mixed with any carrier medium.
