Title: Semiconductor pressure sensor and it's manufacture
Inventor: SATO KIMITOSHI
IPC: H01L29/84
Filed: 1990-02-26
Abstract: PURPOSE:To manufacture a diaphragm of fixed thickness easily by a batch processing by etching the area including at least a section which faces each other with a diffusion resistance formation location of a silicon substrate to an etching stop layer from the back side of the substrate. CONSTITUTION:Metal electrodes 7 are formed so as to be brought into contact with each diffusion resistance 5 and then a protection glass coat 8 is formed to cover the metal electrodes 7 and a silicon oxide 6. On the back of a silicon substrate 1, a silicon nitride 2 is formed which will work as a diaphragm etching mask so that a diaphragm 4 may be formed in conformity with a diffusion resistance formation location. Nextly, the silicon substrate 1 is etched using the silicon nitride 2 as a mask. When an anisotropy etching is performed for a wafer of which the silicon substrate 1 is composed, etching goes on at the fixed angle of 54.7 deg.. When etching reaches a silicon oxide 9, the etching rate suddenly drops compared with one in the silicon substrate 1. Consequently, the diaphragm 4 of uniform thickness can be made on the silicon substrate 1.

Abstract: PURPOSE:To ensure abnormal movement stoppage of a cut sheet loader of a paper feeder by providing a limit switch at a power supply line of a motor for moving the loader vertically so as to stop the motor at the time of abnormal movement of the loader to both upper and lower limits. CONSTITUTION:When a sheet 5 is set on a loader 4, the loader 4 rises through a pulley 2 and a drive wire 3 to bring the sheet 5 into contact with a pick up roller 8. As a result, an upper limit sensor works to stop the motor 1.

Abstract: PURPOSE:To improve a sliding characteristic by forming the stationary cylinder of molded articles of a resin added with a conductive material, exposing this conductive material onto the sliding surface of the stationary cylinder with a magnetic tape and specifying the surface shape of the sliding surface to Ra>0.4. CONSTITUTION:Polycarbonate(PC) is adopted as the base material of the resin to be used and the conductive material added with carbon fibers(CF) is used as the conductive material. The amt. of projection of the CF on the sliding surface of the cylinder and the surface shape of the sliding surface are adjusted by the amt. of the CF to be added and the molding conditions of the cylinder. The relation between the size of the surface shape adjusted by the exposure of the CF and the coefft. of friction is such that the coefft. of friction is confined approximately within 0.2 to 0.3 in an Ra>0.4 range. This coefft. of friction is equal to the coefft. of friction in the case of an aluminum material or below and is confined within a practicable use range. As a result, the increase in the coefft. of friction is obviated by exposing the conductive material added within the resin to the sliding surface until the surface shape of the sliding surface attains Ra>0.4.

Abstract: PROBLEM TO BE SOLVED: To obtain an excellent display which causes neither a flicker nor a decrease in contrast by removing a state wherein a potential is unstable when a ferroelectric film is depolarized from a matrix type liquid crystal display which uses the ferroelectric film. SOLUTION: A ferroelectric film 7 between a signal electrode Y and a pixel electrode 4 is formed of two parts 7A and 7B. The parts 7A and 7B are formed of the same material, the part 7a is a half in film thickness as large as the part 7B, and the are of the part 7A is double as large as that of the part 7B. Consequently, the anti-electric field Ec and residual polarization Pr of the part 7A and the anti-electric field Ec' and residual polarization Pr' of the part 7B are so related that Ec'=2.Ec and Pr'=Pr. A specific reset pulse is applied to the ferroelectric film 7 to orient the dipoles of the parts 7A and 7B positively. Then a specific selection period pulse is applied to the ferroelectric film 7 to invert the dipoles of only the part 7A to the negative direction. Consequently, the total of remaining electric charges at the parts 7A and 7B becomes zero.
