Title: Reflection micro-optical system
Inventor: KUISEKO MANAMI
IPC: G11B7/1387
Filed: 1998-11-25
Abstract: PROBLEM TO BE SOLVED: To obtain a reflection micro-optical system constituted only of two surfaces of continuous shape and having simple shape suitable for glass molding by constituting the system so that both 1st and 2nd surfaces are aspherical, and refracted luminous flux passing through the peripheral part of the 1st surface is reflected on the peripheral part of the 2nd surface, reflected on the center part of the 1st surface again and formed into an image near the top of the 2nd surface. SOLUTION: This system is constituted of the 1st surface S1 being convex to a long conjugate length side and the 2nd surface S2 being convex to an opposite side to the long conjugate length side in order from the long conjugate side, and the refracted luminous flux passing through the peripheral part of the 1st surface S1 is reflected on the peripheral part of the 2nd surface S2, reflected on the center part of the 1st surface S1 again and formed into the image near the top of the 2nd surface S2. Therefore, total reflection coating is applied to the vicinity of the optical axis of the 1st surface S1 and the peripheral zonal band of the 2nd surface S2. The system is a biconvex pickup lens where both the 1st and the 2nd surfaces S1 and S2 are made aspherical. It is conceivable to constitute the biconvex pickup lens where only the 1st surface S1 is made aspherical.

Title: Method of manufacturing semiconductor device
Inventor: MIENO FUMITAKE
IPC: H01L21/316
Filed: 1992-12-15
Abstract: PURPOSE:To grow CVD oxide films of high quality by low temperature processing at a high film growth rate by depositing the oxide film using the reaction gases of hydrazine, nitrogen oxide, and silanes. CONSTITUTION:With a wafer W placed on the susceptor 4, the pressure inside a reaction chamber 2 is maintained at 3Torr by exhausting the gas inside the reaction chamber 2 via an exhaust pipe 7 while introducing into the reaction chamber 2 via the gas inlet pipe 3 disilane gas (Si2H6) at a flow rate of 3sccm, hydrazine gas (N2H4) at a flow rate of 10sccm, and nitrous oxide (N2O) at a flow rate of 150 to 600sccm. Thus, the silicon oxide film is grown under these conditions by varying the temperature of heating the wafer W. Since the decomposition temperatures of silane gases such as SiH4, Si2H6, Si3H6, etc., are in the range 200 to 300 deg.C, it is possible to grow the oxide film at low temperature and at high speeds if the N2O gas is efficiently decomposed.
