Title: Gas etching method
Inventor: YAMADA MITSURU
IPC: C23F1/00
Filed: 1979-10-01
Abstract: PURPOSE: To perform the uniform etching corresponding to predetermined patterns by covering the surface to be etched having been covered with a mask with aperture forming plates and performing etching locally or progressing the same gradually from local to the entire part of the etching surface.  
     CONSTITUTION: In a gas etching apparatus, a photomask blank 3 is covered with aperture forming plates 4 made of an etching-resistant material to form an aperture opposing only to the central part of the photomask blank 3. The central part is lightly etched locally, and the aperture is gradually expanded by gradually moving the aperture forming plates 4 in the arrow directions so that in the final the entire part of the photomask blank 3 is exposed into the plasma. Thereby, the differences in etching rate between the peripheral part and central part of the photomask blank 3 are eliminated and the uniform etching patterns may be obtained.

Abstract: PURPOSE:To form metal insulator semiconductor transistor having high breakdown strength and precision by a method wherein the parts wherein deep low concentration source/drain diffused layers barely activating ion implanted species are located while shallow high concentration diffused layers for contact are separated from a gate electrode are to be selectively ion-implanted. CONSTITUTION:A substrate 9 is drain boron implanted in different ranges using a gate electrode 4 and an oxide film 2 as masks to be heat-treated for activation of ion implanted species. Furthermore, a high concentration source/drain ion implanted mask photoresist 11 is formed extending over the gate electrode 4-P<-> low concentration source/drain diffused layers 10. Next, boron ions are selectively implanted in the photoresist for the formation of shallow high concentration diffused layers. After the removal of the photoresist 11, the whole element is heat-treated for activation of the implanted high concentration ions to form p<+> high concentration source/drain fiffused layers 12. Through these procedures, the deep low concentration diffused layers 10 in less expansion in the lateral direction can be formed.

Filed: 1986-06-04
Abstract: PURPOSE:To stabilize bloating of a magnetic head and a recording/reproducing signal by adopting a streamline structure for the structure of cross section of a side ridge bent part of a beam part for load.

Title: Production of sic whisker
Inventor: SUGIHARA TAKAOMI
IPC: C30B29/62
Filed: 1990-05-17
Abstract: PURPOSE:To produce SiC whiskers having properties including a prescribed average diameter and diameter distribution under control by regulating the particle size of powdery starting material as an Si source to a specified range in production with a solid starting material system. CONSTITUTION:A starting material mixture of starting material as an Si source with carbon is heated to a reaction temp. range in a non-oxidizing atmosphere and SiC whiskers are formed. In this method, the particle size of the starting material as an Si source is regulated to a certain range of <=250mum by classification. The particle size of the starting material affects properties of formed whiskers, especially the average diameter and diameter distribution and the average diameter is reduced by reducing the particle size. In the case of >250mum particle size, unreacted starting material remains in large quantities, segregation is caused and the yield of formation is remarkably reduced.

Title: Thin-film transistor array substrate and manufacture thereof
Inventor: TAKEDA YOSHIYA
IPC: H01L21/336
Filed: 1986-06-03
Abstract: PURPOSE:To obtain an active matrix substrate using a TFT by depositing a transparent electrode and a multilayered film consisting of metal and simultaneously forming a gate electrode and a picture element electrode for display through one-time mask operation. CONSTITUTION:Gate electrodes (11a, 12a) and picture element electrodes (11a, 11b) composed of Cr 12 and ITO 11 are shaped onto a glass substrate 10 through photolithographic etching. An a-Si layer 14 is superposed through an SiNx film 13, and a mask is executed and a gate insulating film and a channel region consisting of a-Si are formed through etching. Al is sputtered, and a mask is executed and a source electrode 15a and a drain electrode 15b are shaped through etching. An active matrix substrate is acquired by three masks in this example, and can be used for reflection type liquid crystal display because the section of an electrode 12b is left in the picture element electrodes, and the number of masks as seen in conventional devices can be decreased only by one. When another devised process is added, five or six masks as seen in conventional devices can be reduced by approximately half.

Title: Apparatus for detecting speed of permanent magnet type brushless alternating current generator
Inventor: MINETOMO KIYOHIRO
IPC: G01P3/46
Filed: 1982-07-21
Abstract: PURPOSE:To simplify the structure of the titled apparatus, by a method wherein the speed of an AC generator is detected by the output voltage of a permanent magnet pilot generator (PMG) at the time of starting and stopping and detected from the output frequency of the AC generator at the time of usual operation. CONSTITUTION:Because an exciting control apparatus 9 is not operated at the time of the starting and the stopping of a permanent magnet pilot generator (PMG) type brushless AC generator, the output of an AC exciter 6 is not issued and the output of an AC generator 5 is zero while PMG 8 outputs voltage proportional to a rotary speed. Therefore, the output voltage of PMG 8 is converted to DC voltage by a rectifier smoothing circuit 14 to shift a speed indicator 4. When a usual operational state is established, the exciting control apparatus 9 is operated and, when an exciting current is supplied to an exciting coil 5a to generate output voltage from the AC generator 5, output voltage having frequency proportional to said speed is added to a speed detecting apparatus 11 through PT10. The voltage from PT10 is converted to DC voltage proportional to output frequency by the F/V converter 13 in the speed detecting apparatus 11. In addition, because a relay X12 is energized when the output of the AC generator is established, a contact 2a is changed over to a reverse direction and the speed indicator 4 is shifted by the output DC voltage of the F/V converter 13. Because speed detection can be performed without attaching a speed detecting sensor to the PMG type brushless AC generator itself at all, the structure of the PMG type brushless AC generator becomes simple.
