Abstract: PURPOSE:To prevent a transconductance from being deteriorated by a method wherein an impurity is doped from insulating films, of a second conductivity type, formed on side-wall parts of a conductor layer; low-concentration regions of the second conductivity type are formed and symmetrical regions, of the second conductivity type, to be used as a source region or a drain region are formed on both sides. CONSTITUTION:A gate insulating film 2, a gate electrode 3 and an impurity- containing insulating film 19 are deposited on a substrate 1. Then, impurity- containing side walls 20 are formed only on side-wall parts of the gate electrode 3 by using an etching operation. After that, ions of arsenic as an N-type impurity are implanted into the substrate 1 by making use of the side walls 20 and the gate electrode 3 as a mask. In addition, a heat treatment is executed; high-concentration N<+> regions 5 are formed in regions where ions have been implanted; at the same time, the substrate 1 is doped with an impurity from the side walls 20 on the side of the gate electrode 3 in the N<+> regions 5; low- concentration N<-> regions 4 are formed. In this manner, an LDD structure having the symmetrical low-concentration N<-> regions 4 on both sides of the gate electrode 3 is formed.

Title: Vector assignment optimization processing system
Inventor: NAGAKURA HIROSHI
IPC: G06F17/16
Filed: 1986-07-15
Abstract: PURPOSE:To reduce the access to a main memory device and to improve the execution efficiency of an object program by substituting two assignment processing with one assignment processing and the transfer processing between required registers or the like on conditions of coincidence between both array data regions, the absence of branching instructions between both processings, or the like. CONSTITUTION:A substitution condition inspection part 21 selects combinations, which meet prescribed conditions such as the absence of intermediate branch statements, from a candidate list and allows selected them to remain as effective combinations. An overlap inspection part 22 determines combinations, where designated regions of both arrays of two assignment statements coincide with each other and which do not overlap areas of arrays of the same names referred by program statements between both assignment statements as the objects of optimization. A substitution processing part 23 substitutes two assignment statements with the transfer processing between required vector registers, the setting processing of a required mask register, and one assignment statement with respect to each determined combination. Thus, the access to the main memory device is reduced to improve the execution efficiency.

Filed: 1990-06-25
Abstract: PURPOSE:To detect abnormality of the controller by detecting the time when the right of using of a bus is permitted after a CPU executes a bus request for using a bus and deciding the time-over. CONSTITUTION:From a bus requester A 22 connected to a VME bus 200, a VME bus request is outputted to a bus arbiter 11 connected to its bus 200. As a result, the arbiter 11 executes a bus arbitration, decides the priority of its VME bus request, and a master A 21 is subjected to bus permission.
