Abstract: PURPOSE:To grasp the existence of a residual film of a nitride film on the surface of SiO2 by referring to a window for substratum detection use in an Si substrate when the nitride film is to be removed by a method wherein the window for substratum detection use is made and the substrate is exposed. CONSTITUTION:An N-type Si substrate 3 is thermally oxidized; a buffer oxide film 2 of SiO2 is formed; a window 4 for substratum detection use is formed in this film 2 by an etching operation. A nitride film 1 covering the buffer oxide film 2 and the window 4 for substratum detection use is deposited. The nitride film 1 in a field part 6 of a semiconductor device and the buffer oxide film 2 are removed by making use of a resist film 5 as a mask; the Si substrate 3 is exposed. The exposed Si substrate 3 is oxidized selectively by heat; a thick oxide film of SiO2 is formed in the field part 6. The nitride film 1 on the window 4 for substratum detection use is removed by using hot and concentrated phosphoric acid. Because the Si substrate 3 inside the window 4 for substratum detection use is exposed in this manner, it is possible to surely grasp the existence of a residual film of the nitride film by referring to a wetting property with reference to water.

Filed: 1988-02-08
Abstract: PURPOSE:To reduce the storage capacity of images requiring no resolution by storing the high-order n bits of a brightness signal in a memory card when a shutter button is depressed in an ON state of a low resolution mode switch. CONSTITUTION:A brightness signal from an image photographed in a low resolution mode is converted into a digital signal by an A/D converter 304 and the high-order several bits of the resolution, e.g., only an MSB in case of a binary image, are stored in the memory card 307. At that time, an analog image signal is effectively quantized by changing the clamp potential of a clamp circuit positioned before the A/D converter 304 or changing the gain of a gain variable amplifier arranged before the A/D converter 304 based on the basis of light quantity information detected by a photometric element 308. Namely, the memory can be effectively used by using it properly in accordance with an image requiring resolution and an image unrequring resolution.

IPC: H03D7/12
Filed: 1988-02-05
Abstract: PURPOSE:To improve mutual modulation characteristics by providing a signal input part with a mixing circuit having linear characteristics. CONSTITUTION:When a signal is inputted from a signal input terminal E, current is generated on a secondary side of a coil L. The current is determined by the frequency and amplitude of the signal and a mutual induction factor between a primary side coil and the secondary side coil and reactance and shows linear characteristics. The skewless signal is inputted to 1st and 2nd differential circuits (Q1, Q2), (Q3, Q4). On the other hand, a local oscillation signal is inputted to a local oscillation signal input terminal A, a signal having a reverse phase against the local oscillation signal is inputted to a local oscillation signal input terminal B, both the signals are mixed, and intermediate frequency signals are extracted from output terminals C, D. Consequently, the generation of mutual modulation distortion can be prevented in the input part. In addition, gain or input impedance can be changed by changing the mutual induction factor between the primary side coil and the secondary side coil or the reactance.
