Abstract: PURPOSE:To realize excellent characteristics by using a simplified process by a method wherein a heat treatment is accomplished in an inert gas atmosphere for a third impurity present in high-concentration source and drain layers in a second MOS transistor region to be laterally diffused for the elimination of offset. CONSTITUTION:The n-channel side of a MOS transistor is covered by a photoresist 11 by a second PEP and boron fluoride (third impurity) ions are implanted into the p-channel side of the MOS transistor for the formation of a high-concentration p-type layer 12. The p-channel side, with a previously formed low-concentration n-type layer being retained in the channel region, has an offset structure. A process follows wherein the photoresist 11 is removed and then a heat treatment is accomplished in a nitrogen N2 atmosphere for the lateral diffusion of boron ions in the p-type layer 12, which eliminates offset. Finally, an insulating film 13 is deposited on the entire surface by CVD, and contact holes are provided as required for the construction of an Al wiring 14.

Filed: 1991-02-22
Abstract: PURPOSE:To hold the continuity of a reproducing signal even when a track jump is generated by rotating a compact disk at a higher speed than a regular rotating speed, and reproducing and storing a data signal more than the necessary quantity. CONSTITUTION:A motor servo-circuit 3 rotates a compact disk 1 at a higher speed than a regular rotating speed, and reproduces an RF signal by a pickup 4 at a higher speed than a usual compact disk player.

Title: Temperature sensor
Inventor: KUZUTA NOBUYUKI
IPC: G01K11/12
Filed: 1983-03-25
Abstract: PURPOSE:To use a temperature sensor even in an explosive atmosphere and to eliminate the influence of an electromagnetically induced noise by using a material which varies in refractive index by temperature by utilizing light and detecting temperature by the deflection of the light. CONSTITUTION:When the temperature of a body to be measured is below a specific value, light from a light emitting element 11 is incident to the 1st refractive index layer 5 from a light emission part 7 through an optical fiber 9 and a critical angle thetath becomes smaller than theta because the refractive index n2 of the 2nd refractive index layer 6 is larger, so light L is transmitted through a boundary surface A. A the temperature of the measured part becomes higher and higher, the refractive index n2 of the 2nd refractive index layer 6 becomes smaller and smaller, and when the critical angle thetath becomes smaller than theta, the light is reflected by the boundary surface A. Then, this light L is received by a photodetection part 8 and transmitted to a photodetecting element 12 through an optical fiber 10 to output an output signal. This output signal when inputted to a comparator 13a is compared with a reference signal to output a detection signal. Consequently, the temperature is measured by the simple structure without any countermeasure to explosion, and the objective measurement range is widened.
