Title: Compound semiconductor device and manufacture thereof
Inventor: HORI YOSHIHIRO
IPC: H01L21/338
Filed: 1990-10-17
Abstract: PURPOSE:To enhance the productivity and the reliability by a method wherein high impurity concentration conductive layers are formed in the positions required for the formation of electrodes while caps are formed of TiN so that the impurities in the conductive layers may be heat-treated to be activated. CONSTITUTION:High concentration ions are selectively implanted using an insulating layer 30 as a mask so as to form conductive layers 34 in a GaAs substrate 10. After finishing the ion implantation step, a TiN layer is formed on the whole main surface of the substrate 10 so that the implanted impurities may be heat treated to be activated. Later, the needless parts of the TiN layers 36 are etched away so as to use the residual TiN layers 36 as the contact electrodes with the conductive layers 34. On the other hand, the TiN layers 36 working as the caps avoiding the evaporation of As during the heat treatment step also not reacting to the GaAs even at high temperature can fill the role of the highly reliable electrodes. Furthermore, the TiN layers 36 hardly reacting to the Al can erect an Al/TiN structure thereby enabling the manufacturing process to be made dry one.

Abstract: PURPOSE:To draw a graphic on a screen with the sense of handling the head of a free parallel rule device and writing tools by allowing one cursor device to move and rotate a right-angled scale line and allowing the other cursor device to designate a coordinate position. CONSTITUTION:When an operator designates two points on a digitizer 4 by a first cursor device for drawing a straight line, for example, the straight line having two points on both ends is displayed on the digitizer 4 in the case of drawing a straight line. At the time of drawing the straight line on the digitizer 4, the right-angled scale line 64 on the digitizer 4 is moved in parallel to a deseired position, rotated by a deseired angle to draw the graphic on the digitizer 4 with the right-angled scale line 64 as a reference by operating a second control cursor device 54. When the right-angled scale line 64 is brought close to two points or the straight line on the digitizer 4, the right-angled scale line 64 is pulled into two points or the straight line and overlapped with two points or the straight line. Thus, an operation can be executed with the sense of handling the free parallel rule.
