Title: Manufacture of photoelectric conversion semiconductor device
Inventor: SATO KEIJI
IPC: H01L21/225
Filed: 1994-08-24
Abstract: PURPOSE: To reduce the dark current by forming an oxide film on a silicon as a mask in the step of forming a P<+> type impurity region, and further forming a nitride film thereon. CONSTITUTION: An oxide film 31 is formed on the surface of an N<-> type semiconductor substrate 1 by thermal oxidation, a nitride film 32 mainly containing Si3 N4 is formed thereon, patterned, and a P<+> type region is formed with the film 32 as a mask. Thus, a natural oxide film 33 of the surface of an opening is first removed to expose the active surface of silicon. Then, boron compound gas is introduced to the active surface of the substrate 1 to form boron or boron silicide film 34. The film 32 prevents the boron from being doped with the surface of the substrate 1. Then, impurity atoms are activated and P<+> type impurity region 2 are simultaneously formed by annealing to remove the boron silicide layer retaining on the surface by etching or oxidizing.

Title: Constant speed running device for vehicle
Inventor: HAYAMA MAMORU
IPC: B60K31/00
Filed: 1985-09-11
Abstract: PURPOSE:To reduce the frequency of shifts between speed change gear stages, by issuing a specific signal when the difference between a set vehicle speed and an actual vehicle speed exceeds a predetermined value so that a speed change gear is shifted into a low speed stage when the signal may be obtained continuously during a first set period, but is changed over into a high speed gear stage when the signal may not be obtained during a second set period after the delivery of the signal being terminated. CONSTITUTION:When an actual vehicle speed is lower than a set vehicle speed, a control unit 22 delivers a specific signal to a transistor 38. If the specific signal may be obtained continuously during a first period from the time of delivery of the signal, an automatic speed change gear 2 is shifted from a high speed gear stage into a low speed gear stage. Further, when the difference between an actual speed and a set vehicle speed is less than a predetermined speed, no specific signal is issued. If the specific signal may not obtained continuously during a second set period from the time of termination of delivery of the specific signal, the speed change gear 2 is shifted from the low speed gear stage to the high speed gear stage. Accordingly, the frequency of shifts between the speed gear stages may be reduced during running on an ascending slope.
