Filed: 1990-07-11
Abstract: PURPOSE:To prevent junction damage of a diffused region on a semiconductor substrate by providing the same conductivity type second diffused region as that of a first diffused region on the substrate, and forming it through a first conductivity type semiconductor layer. CONSTITUTION:An N-type source diffused region 12 is formed on a P-type semiconductor substrate 11. A P-type epitaxial layer 16 having about 1mum of thickness is formed on the substrate 11 and the region 12 by epitaxial growth, and the P-type semiconductor substrate is formed. An N-type diffused region 17 is formed so that the region 12 is brought into contact with an exterior. When an overvoltage applied to a drain diffused region 13 on the substrate becomes a set voltage or higher, it is operated as a parasitic bipolar for vertically discharging toward the region 12 connected to a ground via the region 17 buried in the substrate, and an electric field concentration of the part of a junction is suppressed. Thus, a junction damage of the diffused region is prevented.

One specified pixel is set to be the pixel of interest X, the result of the sum of products between a 5×5 peripheral pixel and a multi-valued filter pattern Ft is substituted for a variable Nb and a multi-valued filter processing 6a is executed. The product-sum operation result Nb between the 5×5 peripheral pixel of the pixel of interest X and the pattern Ft becomes the number (0-25) of the black pixels in the peripheral pixels. A conversion density value Dh corresponding to the black pixel number range to which the number Nb of the black pixels belongs is read. It is compared with the threshold Th of the pixel to which a dither matrix Md corresponds. When Md is larger than Th, the pixel X is made to be the black pixel. When it is smaller, it is set to be a white pixel and a processing is completed.
