Title: Manufacture of semiconductor device
Inventor: WATANABE TOSHIHARU
IPC: H01L21/302
Filed: 1985-12-23
Abstract: PURPOSE:To prevent an element isolation-oxidizing film from being formed in an overhung shape even if it is etched in a transverse direction, by adding impurities in advance to the surface of the element isolation-oxidizing film, to form an impurity region high in an etching rate. CONSTITUTION:An element isolation-oxidizing film 3 is doped with impurities to form a PSG region 4. Mask members 6 and 7 are selectively removed to form an opening at the part except the oxidizing film 3. A substrate 10 is etched through the opening to form a groove 8. Isotropic etching also makes a heat oxidizing film 1 be etched to form a cavity 9. When the cavity 9 attains to the oxidizing film 3, the region 4 formed above it is first etched because the region 3 is higher in an etching rate than the oxidizing film 3 and its etching advances fast. Hence, the oxidizing film 3 is prevented from being overhung at the end part facing the groove 8.

Filed: 1997-10-23
Abstract: PROBLEM TO BE SOLVED: To provide a method for generating a DSA image more accurately. SOLUTION: This method 10 includes a process 14 for generating a matching point, a process 16 for generating image distortion from a locally adaptive image and a process 18 for executing logarithmic subtraction to generate a DSA image. In the case of generating the matching point, a set of 2-dimension points in a mask image and points corresponding to those points in an opaque image are introduced. After the generation of the matching point is executed, the generation of image distortion from the locally adaptive image is executed by using the matching point of an image to an image. That is, a conversion function that maps a just matched point in the mask image with a point corresponding to those points in the opaque image is generated.  The generated conversion is then applied to data of the mask image and a logarithm of a pixel value in the converted mask image is subtracted from a logarithm of a corresponding pixel value in the opaque image.

Abstract: PROBLEM TO BE SOLVED: To obtain a navigation system by which a guidance display can be started rather early without giving a user a feeling of troublesome by displaying a road map nearly continuously and also displaying guidance information on a next course change intermittently for a short time. SOLUTION: A required road map is written into a bank A at a frame memory. When a vehicle makes a right turn at a crossing α, the enlarged bird's-eye view map of a crossing β at which the vehicle makes a left turn and the display screen of guidance information indicating the left turn are written into a bank B at the frame memory. Then, display data in the banks A, B are read out in the following manner so as to be displayed. That is to say, a road map inside the bank A is read out at a frequency of about 30 frames per second, and the guidance information inside the bank B is read out at a frequency of about one to three frames per second in the intervals. (In both cases, the display time is about 30msec per frame.) Consequently, the guidance information functions as subliminal information.  Then, when the vehicle comes close to the crossing β, a road map into which the guidance information is fitted, is written also into the bank B, and the display screen indicating the guidance information is fitted into the road map so as to be displayed.
