Patent JP-H11126885-A (JP)
Title: Semiconductor device and manufacture thereof
Inventor: ITO TOYOJI
IPC: H01L27/10
Filed: 1997-10-24
Abstract: PROBLEM TO BE SOLVED: To lessen the undulations of the surface of a base layer to be formed with a ferroelectric thin film, and to inhibit the precipitation of foreign substances in the surface of an inter-layer film or the like at crystallization of the ferroelectric thin film at high temperatures by a method, wherein an insulating film is formed as a boron and phosphorus-containing silicon oxide film and a boron concentration in the silicon oxide film is set at a specified value or lower. SOLUTION: For example, a silicon oxide film (BPSG film) 6 having 4.0 wt.% of boron concentration and 5.0 wt.% of phosphorus concentration is formed on a semiconductor substrate 2, having a polysilicon wiring 1 of a thickness of 400 nm, in thickness of 800 nm. A platinum thin film 4 is formed on the film 6 in thickness of 200 nm as a lower electrode and a ferroelectric thin film 5 using a strontium bismuth tantalum oxide as its material is formed on the thin film 4 in thickness of 200 nm. When the boron concentration in the BPSG film is high, an oxide-containing boron is precipitated in the BPSG film at the time of the crystallization of the thin film 5. This precipitation causes the defective shape of a capacitor, a disconnection of the wiring 1 and a bridge.  Particularly, by setting the boron concentration in the BPSG film 6 at 4.5% or lower, the production of oxides containing boron can be prevented.

Abstract: PURPOSE:To generate a light beam with high energy density by performing optical amplification by the guide emission of a semi-conductor laser, and using a two-axial crystal body as an optical multiplexing and demultiplexing means and multiplexing incident light. CONSTITUTION:An optical resonator consists of semiconductor lasers 16A-16C whose one-mirror-surface reflection factor is 90% and a 2nd reflecting mirror 22 whose reflection factor is 2-5% and the two-axial crystal body 10 is arranged as the optical multiplexing and demultiplexing means between them. A light beam from a laser light source is refracted in a conic shape by the two-axial crystal body 10and emitted from a surface 10B which generates multiplexed circular polarized light. The circular polarized light is converted by a 1/4-wavelength plate 18 into plane polarized light, which incidents on a reflecting mirror 22 after passing through a beam splitter 20. Part of the light is sent back by the reflecting mirror 22 along the onward path and reflected by a laser reflecting surface. Thus, the light travels reciprocally and is amplified by the guide emission of the lasers to generate one mode wave by the beam splitter, so that the light is emitted from the reflecting mirror 22 when reaching specific intensity.

IPC: G03G5/10
Filed: 1993-11-25
Abstract: PURPOSE:To lessen spilling of a photosensitive agent by coating and to coat the uniform photosensitive layer free from unevenness by washing a un-machined aluminum pipe formed by drawing extruded pipe stock by a specific solvent after drawing. CONSTITUTION:The solidification of a highly viscous and oily lubricant sticking to the surface of the un-machined aluminum pipe 1 used at the time of drawing does not progress so much if the un-machined aluminum pipe 1 produced by drawing the extruded pipe stock is within three days after the drawing. The aluminum pipe 1 is, thereupon, washed by the solvent having a degreasing power of a KB value of >=20 while the aluminum pipe is in such a state. As a result, the highly viscous and oily lubricant is more easily removed and the detergency enhanced. Further, the aperture 4' of the defect 4 on the surface of the aluminum pipe 1 is washed by the solvent while force is applied thereon in the direction of expanding the aperture, by which the solvent is intruded into the inside of the defect 4 and the highly viscous and oily lubricant clogged in the defect 4 is more easily removed. The higher detergency is thus obtd.
