Abstract: PURPOSE:To form a deposit film with excellent evenness in thickness and quality of film on the surface of a substrate while improving the efficiency of deposit film by a method wherein a discharge diffusion preventing body is arranged outside a space between one electrode surface and the other electrode surface. CONSTITUTION:A discharge diffusion preventing body 16 made of a conductive material is arranged outside a space A between one electrode surface of cathode electrode 4 and the other electrode surface of an opposing electrode 6. The cylindrical discharge diffusion preventing body 16 erected to encircle the space A from the bottom surface of depositing chamber 2 is provided with the height reaching the peripheral part of opposing electrode 6.

Title: Semiconductor memory
Inventor: NAKAYAMA RYOZO
IPC: G11C17/06
Filed: 1988-01-27
Abstract: PURPOSE:To make a ROM array into fineness or large capacity by using a diode with p-n junction as a memory cell, and detecting the presence/absence of a breakdown current by impressing the reverse bias voltage of the intermediate values of first and second breakdown voltages. CONSTITUTION:When the diode with p-n junction is used as the memory cell and different inpurity density is set on an inpurity diffusion layer on one side corresponding to data, the breakdown voltage goes to 23V or 21V that are the first and second breakdown voltages. And when the reverse bias voltage is impressed, for example, setting the row line X2 of a selected diode at 0V and the column line VR as the intermediate value 22V of the first and second breakdown voltages, the breakdown current is generated or not generated corresponding to the storage data of the selected diode, and the storage data is read out based on the presence/absence of the breakdown current. By constituting a device by using the diode instead of the transistor, it is possible to make the ROM array into the fineness and the large capacity.

Abstract: PROBLEM TO BE SOLVED: To facilitate a wiring design between a chip and a terminal and to improve a wiring characteristic by arranging interface circuits in a main chip in peripheral center parts in the main chip. SOLUTION: Interface circuits 4 in a main chip 2 are dispersed and arranged in the centers of four peripheral sides in the main chip 2. Thus, IP chip connection terminals 5 are dispersed and arranged in the centers of the four outer peripheries of the main chip 2 in accordance with the interface circuits 4. The wiring areas of an IP chip bonding terminal and the IP chip connection terminals 5 are dispersed in the respective peripheries of an IP chip 3 at the back of a mounting substrate 1. Thus, a wiring relation between main chip connection terminals 6 and MCP chip terminals becomes short in terms of distance and wiring becomes easy. Consequently, the dispersion of a wiring distance is suppressed, wiring length is shortened, the congestion of wiring is relieved and the area of the wiring area is reduced.

Abstract: PURPOSE:To realize a low threshold by narrowing the width of a light emitting region and manufacture a low threshold laser with a simplified process by making an n type, part of an n type cladding layer into which a p type impurity is diffused through p diffusion by making use of n diffusion where an impurity reaches the n type cladding layer, but not reach an active layer. CONSTITUTION:An n type diffusion source Si film 9 and a p type diffusion source ZnO:SiO2 film 10 are formed on a wafer. Thereafter, a heat treatment is performed to perform p and diffusions simultaneously, and a quantum well excepting a part which becomes an active layer 3 through low concentration p diffusion that reaches at least a p type cladding layer 2 is made random utilizing a difference between p and n diffusion rates. Simultaneously, part of the n type cladding layer into which a p type impurity is diffused through p diffusion is formed as an n type utilizing high concentration n diffusion that is low in a diffusion rate and that reaches the n type cladding layer 4 but does not reach the active layer 3. Therefore, the active region can satisfactorily be narrowed without consideration of the formation of an electrode, whereby a reduced threshold of a laser can be realized and an n electrode formation region is greatly widened. Thus, the formation of the n electrode can greatly be facilitated.
