Title: Semiconductor ic circuit
Inventor: MOROZUMI SHINJI
IPC: H01L21/762
Filed: 1979-08-21
Abstract: PURPOSE:To minimize a distance necessary for an element separation to the limit by a method wherein a groove is formed on the top of an epitaxial-layer and made a wall for the element separation covering with an oxidized film. CONSTITUTION:The U-shape groove is formed at the portion corresponding to the element separation of a substrate 10. When an epitaxial-layer 12 is grown on the substrate, the groove of the epitaxial-layer is made a groove 13 in slightly languish shape. When thermal oxidation is then applied to the surface, an oxidized film 14 is adhered to the surface and at the same time, there is formed a deep walled groove 15 covered with the oxidized film of narrow width and thickness. With the removal of the oxidized film 14 on the surface, the wall 15 is left behind and used for the element separation. If a thickness of the oxidized film is of the order of 3mum, the element separation becomes completely possible without mutual connection of the depletion layers of the diffusing layers 16 and 17. Whereby the distance required for the element separation can be reduced to 1mum without a special technic of lithography, and the degree of integration can be improved in wide range.

Filed: 1982-06-23
Abstract: PURPOSE:To obtain the position of a defect position in a body to be detected accurately, by providing a function for displaying the bottom surface and center line of the body to be detected. CONSTITUTION:When a switch 6 is turned on, the bottom surface and center line are displayed at a section 8 and corresponding processing is started according to a flow 11. Thus, when an oblique probe 12 is used, there is no bottom surface echo, so the probe 12 is placed at the position of the body 13 to be detected where there is a bottom surface echo, whose bottom surface echo is aligned to a bottom surface line 17. Then, the probe 12 is so set that an a position of ultrasonic wave incident is at a distance (a) from the center of the body 13 to display an ultrasonic wave propagation track, and the center line 16 is set on the intersection with the bottom surface line to start flaw detection processing. When a superimposing switch is turned on after the flaw detection, a superimposing state is entered, and consequently the clear bottom surface and center line are displayed on a picture of the flow detection result to obtain the position of the defect part.
