Filed: 1985-05-02
Abstract: PURPOSE:To enable the increase in withstand voltage and the reduction in resistance of capacitance between wirings by a method wherein the second insulation film is formed so as to become thicker on the first Si film than on the exposed part. CONSTITUTION:After an insulation film 2 is formed over the surface of an Si substrate 1 of the first conductivity type, the insulation film of an element region 3 is removed. Next, an insulation film 2-1 covering the element region is formed; further, a gate electrode 4 covering the whole is adhered, and the part other than the electrode part 4 is removed by photoetching. Thereafter, the insulation film 2-1 is removed by etching with the gate 4 as a mask; then, on oxidation in O2 containing steam, an insulation film 2-2 is formed on the Si substrate 1, and a protection film 6 on the polycrystalline Si 4. Previous addition of high- concentration phosphorus or boron to the electrode causes the protection film 6 to be formed thicker than the insulation film 2-2. Since the layer on the electrode and the insulation film on the channel region are formed at the same time, the structure of small capacitance between polycrystalline Si of the first and second layers and high withstand voltage can be obtained.

Title: Laser-scanning image forming device and optically writing unit therefor
Inventor: NAKAZATO YASUFUMI
IPC: B41J2/44
Filed: 1990-04-11
Abstract: PURPOSE:To improve a product quality and an operational efficiency and to lower a cost by providing a communication means for identifying whether an optically writing unit loaded on a device body can be operated at a pixel density requested by the device body between the device body and said optically writing unit. CONSTITUTION:When an LD unit 30 is loaded on an optically writing unit 12, an SM driver 1 sets a pixel density code, and gates of circuits 81, 82 out of AND circuits 80 - 84 forming a gate group 8 are opened. Each input terminal of an OR circuit 6 serving as a communication means is connected to each line between the gate group 8 and an 1/n divider 4. Therefore, if any of the lines is '1', an identifying signal DPACK is outputted to a CPU 51 through an I/O 54. Therefore, when a pixel density 300dpi or 400dpi is instructed by the CPU 51, the identifying signal is fed back. But, when another pixel density is instructed, the closed gate prevents the feed back of the identifying signal. In this manner, the specification pixel density of the optically writing unit 12 can be easily checked.
