Title: Positioning
Inventor: MURAI FUMIO
IPC: H01J37/304
Filed: 1982-10-20
Abstract: PURPOSE:To enable to attain high precise positioning by forming a positioning target even when the target has shallow step difference structure or sluggish step difference structure by a method wherein the target is made to have deep and steep step difference structure without reducing precision of positioning. CONSTITUTION:Through holes 7 to conduct to a substrate 5 are formed in an oxide film 6. At this time, the target pattern 8 or 9 to be used for positioning is formed at the same time. The circumference of the target part 8 or 9 of the silicon substrate 5 is etched using the oxide film 6 and a photo resist 10 as the mask to form a recessed type 11 or a protruded type 12. An aluminum film 13 is evaporated and an electron beam resist 14 is applied on the whole surface. The target pattern for positioning is detected by an electron beam 15, and irradiation of the electron beam is performed to wiring regions. Aluminum wirings 16 are obtained after passing through the development process and the etching process. The targets 11, 12 have deep step difference structure enabling to present a favorable detection signal, and discrepancy of position is not generated because the targets are formed by one action at the same time with the through holes 7.

IPC: G06F11/00
Filed: 1989-07-15
Abstract: PURPOSE:To accurately detect an abnormal state by connecting the 2nd abnormality continuation detecting means for answering the outputs of the 1st abnormality continuation detecting means and detecting whether respective abnormal states are continued or not in common to respective items. CONSTITUTION:When states detected by sensors S1 to S24 are decided as abnormal states by abnormal state detecting means E1 to E24 and the abnormal states are continued for the previously determined 1st time W1, the generation of abnormality is decided. Namely, counters C1 to C24 detect whether respective abnormal states are continued for the previously determined 2nd time W2 or not and a counter A1 connected in common to respective items detects whether the abnormal states are continued for the previously determined 3rd time W3 or not. When the abnormal states are continued for the 1st time W1 or more, a signal indicating the generation of the abnormal state is outputted from an AND gate G1 and previously determined processing operation, e.g. display for abnormal time is executed. Thus, the abnormal state accurately is detected.

Title: Retry system for check point
Inventor: MORITA KUNIKI
IPC: G06F11/14
Filed: 1987-07-23
Abstract: PURPOSE:To realize the retry processing of a microinstruction by inhibiting the replacement of the contents of a save register before the replacement of the contents of a register is through normally. CONSTITUTION:Each register contains a save register and the contents of the save register are loaded into each register for retry when a hard error occurs. The internal registers excluding those registers contain no save register. A save register control part 12 inhibits the updating of the contents of each save register before the replacement of the contents of the internal registers are through normally. Then the contents of the save registers are replaced only when the replacement of the contents of the internal registers are through normally. Thus it is possible to perform the retry of a microinstruction even in case a reading fault occurs during the replacement of the contents of those internal registers containing no save register.
