Title: Manufacture of compound semiconductor device
Inventor: TANAKA YUUJI
IPC: H01L21/302
Filed: 1984-04-23
Abstract: PURPOSE:To contrive the improvement of performance by realizing FETs of high reliability by a method wherein a gate metal of high melting point is used as the first layer. CONSTITUTION:Si, an impurity dopant of N type conductivity, is ion-implanted into a GaAs substrate 1. A layer 2 of the implanted impurity turns of an N type conductive layer electrically activated in a later process and serves as the channel layer of a FET. After growth of TiW 3 the high melting point metal of the first layer, Al4 the metal of the second layer is grown by resistance heating evaporation. A photo resist 5 is applied and patterned, and an Al4 pattern is formed more finely than the resist pattern 5 by etching the Al4 of the second layer through wet-etching with phosphoric acid. Then, the TiW3 is dry-etched. After an N<+> type conductive layer 6 is formed by Si<+> ion implantation, the photo resist is removed and the TiW3 is anisotropically etched. After removal of the Al4, an SiO2 film 7 is grown and annealed, thus electrically activating the N type ion implanted layer 2 and the N<+> type ion implanted layer 6.

Title: Formation of copy preventing patterns and printed matter
Inventor: KIUCHI MASATO
IPC: B42D15/10
Filed: 1996-03-12
Abstract: PROBLEM TO BE SOLVED: To prevent the densification caused by the overlap of image lines at an intersecting part, in the image lines becoming constant cycle discontinuous lines of a part to which a latent image is applied, by eliminating either one of mutual image lines within a region where image lines cross each other at a part where image lines of constant cycle discontinuous lines cross each other. SOLUTION: The image line E of an image line part 13 being either one of the image lines of the image line part 13 is eliminated in a region where the image lines of the image line part 13 of constant cycle discontinuous lines cross each other. When printed matter having image line constitution is copied by a copier, the image lines of the continuous lines of a part to which no latent image is applied are regenerated and the image lines becoming the constant cycle discontinuous lines of a part to which a latent image is applied are not regenerated or become impossible to regenerate.  Since density difference is generated between the part to which the latent image is applied and the part to which no latent image is applied and either one of the mutual image lines of the image line part becoming the constant cycle discontinuous lines of the part to which the latent image is applied is eliminated in a crossing part, the image lines of the region where image lines cross each other are not densified.
