Filed: 1988-12-27
Abstract: PURPOSE:To make it hardly influenced to the correction accuracy even in the presence of dispersion in the density versus output characteristic of an image sensor by applying arithmetic processing based on a digital picture signal. CONSTITUTION:An image sensor 4 outputs an analog picture signal 14 to a density gradation scale plate 2 lighted by a light source 3, the signal is converted into a digital picture signal 15 at an A/D converter 5 and stored in a line memory 6. A CPU 8 executes the algorithm stored in a ROM 9 to output a density versus output characteristic f(x) of the image sensor 4 based on the content stored in the line memory 6. Moreover, the CPU 8 derives a correction table characteristic g(x) based on a density versus output characteristic h(x) requested by a picture processing section 11 and the derived characteristic f(x) and loads the result to a density correction circuit 7 as a lookup table. Thus, the corrected digital picture signal 16 has the density versus output characteristic h(x).

Title: Manufacture of semiconductor device
Inventor: AKIMOTO MASAO
IPC: H01L21/225
Filed: 1988-12-28
Abstract: PURPOSE:To make low a sheet resistance and moreover, to inhibit the generation of a rosette by a method wherein a patterned Sb glass layer is formed on the main surface of an Si substrate, on which a diffusion mask is not formed, and a thermal diffusion is performed intact in an oxidizing gas-containing atmosphere. CONSTITUTION:An Sb impurity solution is spin-on applied on the main surface of an Si substrate 1, a heat treatment is applied to vitrify the solution and a resist 7 is applied on the surface of an Sb glass layer 3 and is patterned. The layer 3 is etched using a proper etching liquid and diffused layers 4 are selectively formed by a thermal diffusion in an oxidizing gas-containing atmosphere. A diffusion mask is not used, but thin SiO2 layers 8 of 2 to 300Angstrom  or thereabouts are formed at non-diffused regions by a fact that an autodoping is hardly generated in Sb itself and a reaction of the oxidizing gas. Moreover, O2 in the oxidizing gas goes being diffused in the Sb glass layers 8 and bonds with the Sb to activate and further, stops the formation of a rosette. Thereby, with a low sheet resistance obtained easily, the generation of a rosette is inhibited in the diffused regions as well.
