Filed: 1991-10-31
Abstract: PURPOSE:To enhance resistance against soft error or latch-up by embedding insulation film parts containing oxygen or nitrogen atoms deeply in a semiconductor layer in positions corresponding to each high concentration semiconductor active region. CONSTITUTION:Insulation film parts 29, 30 are embedded deeply in a P-type semiconductor substrate 21 at positions corresponding, respectively, to high concentration N-type active regions 23, 24. Since minority carriers can not pass through the embedded insulation film parts 29, 30, soft error can be blocked effectively at these parts. Furthermore, since high concentration N-type active regions 40, 41 and 42, 43 block current flow between the source and the substrate region of CMOS, latch-up resistance can effectively be enhanced.

Title: Data rewriting system for phase change rewrite type optical recording medium
Inventor: KAWANO AKINOBU
IPC: G11B7/30
Filed: 1989-11-07
Abstract: PURPOSE:To prevent such a case where a bit is always formed at the same position when the data are written into a phase change rewrite type optical recording medium, and to improve the repeating performance by scattering the write starting positions of data. CONSTITUTION:A time adjuster 1 produces plural write data (b) of different delay times to the write data (a). A data selector 2 selects one of those data (b) in accordance with a selection signal (c) and sends the selected data to an optical recording medium as the write data (a). The data (b) serve as the signals having various time lags to the write signal (a). Thus the positions of bits produced by the data (b) are different from the data (a). Therefore the signal (c) is varied properly for each write and a proper signal is selected out of the data (b) as the write data (d). Thus it is possible to evade such a case where the bits are formed at the same position.
