Patent JP-H02119263-A (JP)
Title: Semiconductor device and manufacture thereof
Inventor: TSUJI KAZUHIKO
IPC: H01L21/822
Filed: 1988-10-28
Abstract: PURPOSE:To form an electrically good connection which does not cause a mutual diffusion of impurities even when semiconductors or the like of different conductivity types are connected directly by a method wherein an impurity ion-implantation layer used to prevent a mutual diffusion of impurity atoms is formed at a junction face of semiconductors of different impurity concentrations or at a junction face of impurity layers of different conductivity types. CONSTITUTION:An impurity ion-implantation layer 14 or 7 used to prevent a mutual diffusion of impurity atoms is formed at a junction face of semiconductors 12, 13 of different impurity concentrations or at a junction face of impurity layers 5, 6 of different conductivity types. For example, impurity introduction layers 2, 3 into which an impurity of an n-type conductivity type and an impurity of a p-type conductivity type have been introduced individually are formed in a semiconductor substrate 1; a polycrystalline silicon film 3 containing an n-type impurity and a polycrystalline silicon film 6 containing a p-type impurity are formed on them via an insulator film 4; a barrier region 7 into which nitrogen ions of 4X10<16>ions/cm<2> has been implanted at 1.5keV by an ion implantation method is formed between them. A low-resistance conductor layer 8 composed of a high-melting-point metal such as titanium or the like or titanium silicide is formed on the barrier region 7.

Title: Digital pattern generating device
Inventor: NIIMI YOSHIHISA
IPC: G01R31/28
Filed: 1985-12-05
Abstract: PURPOSE:To measure and diagnose various kinds of time relations by providing a time measuring means which measures the optional one-bit time relation of a signal of digital pattern. CONSTITUTION:For example, when a single period is measured, a pattern program is generated to output a digital pattern signal Sb from a digital pattern generating circuit 2, and then the program begins to be executed at the address 0 and ends at the address 2 and the signal Sb goes up to an H level only during the execution of the address 1. The period of the address 1 is set to a period T1 with a control signal Sc, so the signal Sb is a single-shot pulse with pulse width equal to the period T1 and a counter 3 measures the single-shot period. When continuous periods are measured, the signal Sb is outputted 2 and then the signal Sb becomes continuous pulses of T1Xm because an instruction for executing the same address plural times (m) is described in the address 1 of the program and the period of the address 1 is set to the period T1 with the signal Sc, so that the integral values of the continuous periods is measured 3. Consequently, malfunction such as the misgeneration of a rate signal Srt is detected.
