Title: Manufacture of semiconductor element
Inventor: YAMAMOTO SHINSUKE
IPC: H01L29/812
Filed: 1988-07-20
Abstract: PURPOSE:To reduce a short-channel effect without increasing the thickness of an insulating film by a method wherein a gate is formed using a material having a compressive stress and the insulating film having a tensile stress is formed on a semiconductor substrate in contact with the sidewalls of the gate. CONSTITUTION:A gate 13 having a compressive stress (a) acts, for example, in such a way that the gate 13 transfers the stress (a) to a semiconductor substrate 11 to generate a piezocharge (c) and the distribution of carriers in a channel region, which is induced in an active layer 12 by applying a gate voltage, is changed. Moreover, an insulating film 15, which is bonded to the gate 13 and has a tensile stress (b), generates the stress (b) in the same direction as that of the gate 13 in the bonded surface with the gate 13, transfers the stress (b) to the substrate 11 to generate a stress (c) and moreover, the stress (c) generates a piezocharge. Thereby, the film 15 acts in such a way that the distribution of the carriers in the channel region is changed like the gate 13. Accordingly, a short-channel effect is reduced by a synergistic effect due to the stress (a) of the gate 13 and the stress (b) of the film 15.

Title: Programmable controller
Inventor: NAGANO DAISUKE
IPC: G05B9/02
Filed: 1985-08-20
Abstract: PURPOSE:To protect the contents of an objective memory by providing a protection switch of hardware onto a programmer and a watchdog timer circuit into the main body of a programmable controller. CONSTITUTION:A protection switch 9 is turned on when a CPU 3 is executing a normal program. Thus the memory write signal supplied to a RAM 6 is always kept at a high level owing to the logical constitution as shown in the diagram even though the memory write signal is delivered from the CPU 3. As a result, the writing is impossible to the area of the RAM 6 and therefore the contents of the RAM 6 can be protected. When a watchdog timer circuit 8 detects an error, the write signal supplied to the RAM 6 is always kept at a high level regardless of the state of the switch 9. Thus the contents of the RAM 6 can also be protected.
