Abstract: PURPOSE: To enhance the breakdown strength characteristics of high breakdown strength MOS transistor by a method wherein the upper end of a part near the substrate surface of an N-type drain diffused layer corresponding to the stepped part of a gate insulating film is depressed in the opposite direction to a channel region. CONSTITUTION: An N-type drain diffused layer 2 is formed on a P-type silicon substrate 1 by implanting phosphorus ions for thermal diffusion so that an oxide film 3 may be formed on the whole surface of the silicon substrate 1 to etch away the oxide film 3 on the region where-on a channel and an N<+> type drain diffused layer are to be formed later using a photoresist 4 as a mask. Next, when the photoresist 4 is removed for thermal oxidation to form a gate insulating film 5 having a film thickness stepped part X on the end part of the N-type drain diffused layer 2 for ion implantation, a P-type implanted layer 6 is formed only below the thin parts 5A of the gate insulating film 5.  Accordingly, the electric field on the stepped part X of the gate insulating film 5 is lessened thereby enabling the deterioration in the breakdown strength and the insulation breakdown, etc., to be prevented.

Filed: 1984-01-31
Abstract: PURPOSE:To obtain a picture of high quality by correcting changes in the quantity of X-rays reaching the surface of a film, which are caused by the distance changing with the move of an irradiation device, by means of changing the number of pulses or the pulse width of the pulsed irradiation. CONSTITUTION:A signal, which is proportional to the square of the distance between an X-ray tube 1 and a detection device 2, is inputted to a pulse-number setting circuit 6. The pulse-number setting circuit 16, including an A/D conversion circuit, generates a numerical output in inverse proportion to the input signal as the pulse-number setting output. A standard clock signal generating circuit 18 outputs the standard clock signal, which is counted by a counter contained in an irradiation signal generating circuit 17, and each time it reaches the numerical value of the pulse-number setting output given by the pulse-number setting circuit 16, an irradiation signal with a certain width is generated. Therefore, the irradiation intervals change in inverse proportion to the square of the distance between the X-ray tube and the film, and the quantity of X-rays reaching the film surface is maintained at a constant level.
