Title: Light source light quantity control device and laser light quantity control device
Inventor: AOI SHIGERU
IPC: H01S5/06
Filed: 1988-02-29
Abstract: PURPOSE:To exactly control the light quantity of a light source by removing only a signal part, in which a light source driving time per unit time between modulating signals is always constant, at the time of recording and detecting radiating light quantity. CONSTITUTION:When recording operation is commanded, a control circuit 13 operates a switch 7 and impresses a voltage 8 for recording to a differential amplifier 6 and a switch 4 is driven. Thus, light quantity L from a laser 1 is detected by a sensor 2 and the sample hold of an output S1 of an amplifier 5 is executed by a sample and hold circuit 12 in a synchronizing signal area. Since the average light quantity of the synchronizing signal is always constant, by inputting an output signal S2 of the circuit 12 to the amplifier 6 and executing feedback, the control of the light quantity can be executed even in a recording signal area.

Abstract: PURPOSE:To prevent punchthrough due to an ion implantation by forming a polycrystalline Si film of an upper layer in which an impurity is not diffused on a polycrystalline Si film of a lower layer in which an impurity is diffused, and performing ion implantation using the two layers as masks. CONSTITUTION:A field oxide film 2, a gate oxide film 3 and a polycrystalline Si film 12 are formed on one main face of a P-type Si substrate 1. Phosphorus 5 is thermally diffused in the film 12. Then, a polycrystalline Si film 13 is formed on the film 12, Thereafter, with a resist as a mask the films 13, 12, 3 are etched to expose the parts which become the source, drain regions of the substrate 1. Subsequently, with the films 12, 3 as masks arsenic 6 is ion implanted. Then, the implanted arsenic 6 is diffused by a heat treatment, thereby forming source, drain layers 7. According to this manufacturing method, since the film 13 can be used as a mask for the ion implantation in a state that Si atoms of noncrystal state are presented at random, it can prevent local punchthrough of the impurity ions to a channel region.
