Title: Manufacture of semiconductor device
Inventor: SENDA KOJI
IPC: H01L21/263
Filed: 1987-01-08
Abstract: PURPOSE:To realize remarkable improvement in the yield of an integrated circuit on a quartz substrate by providing a partially thick silicon splashing preventive band of polysilicon between the devices. CONSTITUTION:After forming a polysilicon plashing preventive band 4 with polysilicon on a quartz substrate 1, the polysilicon 2 is stacked on the entire surface including the silicon splashing preventing band 4. In the laser recrystallization process, when the laser scanning is not carried out, it the silicon splashes by some reason, for example, at the point A, such splashing is continued after the point A. When the laser scanning comes to the silicon splashing preventive band 4, the polysilicon film is very thicker in this region than the other region. Therefore, since the dissolving condition of polysilicon is suppressed, splashing of siliconstops and after the point B, stable recrystallization can be conducted. Thereby, the manufacture yield can be improved remarkably.

Then, CPU supplies an enable signal 4 to the register 14 for identifying which interruption causes it is and it reads the register 14. At the same time, the enable signal is supplied to the reset terminal R of an S-R latch 13 via an AND gate 15 and the output of the latch 13 is obtained from the terminal Q. Thus, interruption information is released by adding the signal to the circuit 12.

Inventor: TANAKA MASAO
IPC: G05B19/416
Filed: 1984-01-11
Abstract: PURPOSE:To control stoppage at a constant distance at a fixed decelerated speed irrespectively of the speed, by running a moving body at the same speed during a period corresponding to the speed from a moment when the body passes through a stop signal issued point and then reducing the speed at a fixed decelerated speed. CONSTITUTION:At the moment when the moving body passes through a stop signal issuing point, a stop signal contact 5 is closed and another stop signal contact 18 is opened and an acceleration adjustor 7 is held at the output speed signal V at this moment and, at the same time, an integrator 15 starts its integrating operation. When the output of the integrator 15 coincides with the set signal of a comparator 16, it is controlled that a deceleration signal is outputted to a deceleration adjustor 6. When the moving body is stopped from an optional running speed which is lower than the maximum speed, the moving body is decelerated at a fixed speed after running at the optional running speed for a time period corresponding to the running speed. Therefore, the moving body can be controlled at a fixed decelerated speed for a fixed distance irrespectively of the speed when a stop signal is issued.
