Title: Semiconductor device and production process thereof
Inventor: MAMENO KAZUNOBU
IPC: H01L21/768
Filed: 1994-07-07
Abstract: PURPOSE:To easily obtain a semiconductor device having an insulation film having a high reliability and high insulation effect in a low temp. process. CONSTITUTION:N radicals 3 are introduced into a silicon oxide film (gate oxide film) 2 to thereby block B ions from passing through a channel region to result in an adverse influence on the characteristic of this region even the ions segregate from a gate electrode. If a high current flows through the gate electrode, the insulation film hardly deteriorates. The N radical introducing step can be easily made at low temp. and hence the oxide film 2 is little damaged.

Title: System for testing line state
Inventor: SAKAKI KOSUKE
IPC: H04L29/08
Filed: 1992-05-25
Abstract: PURPOSE:To provide the system for testing the line state capable of accurately discriminating the success or failure of TCF with simple processing. CONSTITUTION:In the step S1, when the TCF is judged to be received, the processing proceeds to steps S2 and S3, activating timers Ta and Tb. Then the processing proceeds to the step S4, discriminating whether or not a one-byte TCF signal is received. When one-byte TCF signal is received and the processing proceeds to the step S5, the discrimination whether or not one-byte reception data are '0', is performed. When discriminated as 'positive' and the one-byte reception data are discriminated as '0', the processing proceeds to the steps S6, discriminating whether or not the Tb timer becomes zero second. When the discrimination in the step S6 is positive, the TCF is judged to be successful. In other words, the time regulated by the Tb timer and the reception data of the TCF signal are '0', the TCF is judged to be successful.
