Patent JP-H0254929-A (JP)
Title: Plasma processor
Inventor: IWAKI YOSHIO
IPC: H01L21/302
Filed: 1988-08-19
Abstract: PURPOSE:To perform the temperature control in a reaction tube chamber when plasma reaction is proceeding by leading plasma through a plasma lead-in port to a wafer supported in an inner electrode and employing a hollow structure for enabling passage of water or other thermal medium thereby enabling temperature control in the reaction chamber. CONSTITUTION:Upon application of high frequency voltage from a high frequency power source 3A onto a reaction tube 1, gas plasma is produced between the reaction tube 1 and an inner electrode 6. Consequently, excited radical plasma passes through a plasma lead-in port 7 and functions onto a wafer W inserted into the electrode 6 thus carrying out etching or ashing. At this time, gas plasma produced in the reaction tube 1 does not function directly onto the wafer W but radical plasma ions function onto the wafer W in the electrode 6. The grounded electrode 6 is heated and the interior of the reaction chamber can be cooled by feeding water or other thermal medium into the electrode 6, and thereby the temperature in the reaction chamber can be controlled.

Title: Noise filter
Inventor: OKUBO AKIRA
IPC: H03H7/075
Filed: 1988-08-19
Abstract: PURPOSE:To suppress the production of a waveform distortion by connecting a resistor in parallel with an inductive element. CONSTITUTION:Resistive elements R1, R2 are connected respectively in parallel with inductive elements L1, L2. As a result of observing waveform across the noise filter, the distortion in the waveform of an input signal Si and an output signal So of the noise filter is suppressed and a nearly smooth waveform is obtained. As to the output signal So, for example, distortion such as ringing or overshoot is suppressed, the leading characteristic is excellent and the peak value to a substantial digital signal S is not almost increased. Thus, effective noise rejection is attained by using the noise filter without distorting the digital signal waveform.

Title: Silicon carbide-made jig cleaning method
Inventor: NAKAMURA OSAMU
IPC: H01L21/68
Filed: 1994-08-31
Abstract: PURPOSE: To provide a method of cleaning silicon carbide-made jigs used for making semiconductors. CONSTITUTION: Silicon carbide-made jigs having high-purity silicon carbide surface coats for making semiconductors (e.g. high temp. jigs, boats, susceptors etc. for chemical vapor deposition apparatus) are dipped in a hydrochlorate nitrate water soln. or nitrate hydrofluoride water soln. of 10vol.% or more for 30min or more.

Patent JP-H0371120-A (JP)
Title: Projection device
Inventor: HANDA SHUNJI
IPC: H04N5/74
Filed: 1989-08-10
Abstract: PURPOSE:To simply adjust the color purity or color temperature of a projected picture by arranging a pair of mirrors for reflecting 1st light out of red, blue and green beams and a pair of mirrors for reflecting 2nd light so as to be rotated as pairs respectively around axes vertical to incident and reflecting planes. CONSTITUTION:If a dichroic mirror 2 is rotated in the direction of 22 when a light source intensively contains a blue light component, the blue light component can be reduced by shifting the reflection characteristics of the mirror 22 to the short wavelength side. In said status however, the center of the optical axis is shifted to the right direction from a projection lens and projected light may be lost. When a mirror 4 which is a part of a pair with the dichroic mirror 2 is rotated in the direction of 42 which is the same direction as the mirror 2, the center of the optical axis is held at the center position of the projection lens, so that the loss of the projection light can be suppressed. If the red light component is small, the component can be increased by rotating dichroic mirrors 3, 5 as a pair.

Title: Method for formation of interlayer dielectric
Inventor: AOI NOBUO
IPC: H01L23/522
Filed: 1999-07-23
Abstract: PROBLEM TO BE SOLVED: To form an interlayer dielectric which is excellent in heat resistance by making degas phenomenon hardly occur by forming an interlayer dielectric consisting of an organic/inorganic hybrid film through plasma polymerization of alkoxyl group and organic alkoxysilane having organic group combined with silicon. SOLUTION: A first main raw material is organic alkoxysilane having alkoxyl group and organic group combined with silicon. Organic alkoxysilane only, or a mixture is used. A second main raw material is Si-O-Si combination or organic silicon compound with Si-N-Si combination and hexamethyldisiloxane, etc., are mentioned. For performing plasma polymerization for organic alkoxysilane such as methyltriethoxysilane, an organic component of organic alkoxysilane is effectively taken in an organic inorganic hybrid film. Since generation of silanole group is thereby restrained, degassing phenomenon caused by remaining silanole is hard to occur.
