Title: Manufacture of semiconductor device
Inventor: SUGITA MASAO
IPC: H01L21/302
Filed: 1985-08-29
Abstract: PURPOSE:To prevent the formation of a texture to increase the etching rate and of an abnormal part of composition in a PSG layer formed on the step difference part, by implanting phosphorus ions in the insulating layer and redistributing the implanted phosphorus in an insulating layer by thermal treatment. CONSTITUTION:An insulating layer 104 constituted of silicon dioxide as a main component is stuck so as to cover a wiring pattern 3 formed on the semiconductor substrate 1. The phosphorus ions are implanted in this insulating layer 104, and the implanted phosphorus is redistributed in the insulating layer 104 by thermal treatment. In order to form a second PSG layer 14 which has nearly uniform P density for its whole part, the implanted phosphorus is redistributed by the annealing in nitrogen atmosphere. A contact window 7 to expose the lower Al wiring layer 3 in a second PSG layer 14 is formed by the formation of the side surface 7 of the contact window 7 so as to incline by a reflow process. Then an aluminum layer is formed, which is subjected to patterning to form the Al wiring layer 9.

Filed: 1995-07-26
Abstract: PROBLEM TO BE SOLVED: To attain high precision resist removal by dissolving the resist applied on a substrate with a stripping agent and cleaning the substrate with a supercritical fluid soluble in the resist and stripping solution. SOLUTION: A material A to be cleaned (semiconductor substrate) to which the resist is stuck is dipped into the stripping solution 1 of diethylene glycol monomethyl ether heated at 40 deg.C, which is filled in a stripping vessel 2 for 2-3min. In this way, the resist applied on the material A to be cleaned is dissolved. Next, the material A to be cleaned after the resist is dissolved by the stripping solution is housed in a pressure resistant rinse vessel 3 before the vessel 3 is hermetically closed. And the material A to be cleaned is cleaned for 3min while pouring the supercritical carbon dioxide 4. After the cleaning with the supercritical carbon dioxide 4 is completed, the cover 3a of the rinse vessel 3 is opened to leave the inside of the rinse vessel 3 to ordinary temp. and pressure. Then the material A to be cleaned is dried without generating stain since the supercritical carbon dioxide 4 is instantly gasified and vaporized.

Abstract: PURPOSE:To form uniform single crystal thin film by removing, after depositing a semiconductor film, an insulating film thereunder, burying a cavity area by single-crystallization, rejecting the generation of crystal nucleus of undesirable orientation and extending easily a single crystal film up to a dielectric substance material film. CONSTITUTION:An SiO2 film 2 is deposited in the specified thickness on a high purity single crystal substrate 1 by the CVD method, the film 2 is left in the form of a band by the ordinary photo etching method while the other area is removed by the etching, exposing the substrate surface. Then a polycrystalline Si 3 is deposited in the specified thickness by the LPCVD method. In succession, the Si<+> ion in the specified condition is ion-implanted in order to form an amorphous Si from the polycrystalline Si 3. The deposited Si of the SiO2 band is ethched, exposing the SiO2 band in such area and the amorphous Si is left in the direction of SiO2 band length. The SiO2 is then dissolved by the fluoric acid forming a cavity, and the surface is annealed at the specified temperature under the N2 ambient. Thereby the amorphous Si shows the epitaxial growth at the single crystal region up to the upper part of cavity. Thus, a single crystal thin film can be obtained.

Patent JP-S62172234-A (JP)
Title: High-tension transducer
Inventor: ENGERAA POORU
IPC: G01L23/10
Filed: 1986-08-18
Abstract: A transducer, particularly for ballistic high pressure measurements, comprises an assembly body, with a shoulder sealing section and a sensor member, which can be received in a recess in the assembly body. The assembly body can be screwed into a component, e.g. a gun barrel, the measurement area on the sealing section being sealed. The assembly body has a tubular extension extending beyond the sealing section, which extension encompasses the sensor member on a cylindrical fitting face. The high sealing forces required for sealing the measurement area are kept remote from the sensor member. The measuring sensitivity of the transducer is therefore independent of the prevailing tightening torques. A cylindrical gap between the sensor member and assembly body provides additional insulation between the sealing forces and the prestress forces prevailing in the sensor member. The cylindrical gap is sealed against the pressure medium by a force fit or weld between the assembly body and the sensor member. A reception space can be provided ahead of the diaphragm section of the sensor member, which reception space can be formed by an annular section projecting from the diaphragm section, and can be provided with replaceable thermal and erosion protection devices.
