Title: Peak value detecting circuit
Inventor: AKUNE SATOSHI
IPC: G01R19/04
Filed: 1986-07-23
Abstract: PURPOSE:To obtain a detecting circuit capable of starting A/D conversion early after peak hold by outputting conversion start command from a timing controller to an A/D converter in response to the output of a peak presence detecting circuit. CONSTITUTION:Receiving signals to be measured at an input, a peak hold circuit 2 holds a peak value and feeds an output to an A/D converter 3, wherein the output is converted to digital signals. A peak presence detecting circuit 6 is composed of a peak hold detecting circuit 7 and a timer 8. The circuit 6 compares the signals to be measured and the output of the circuit 2 with each other, detects a peak point and feeds an output with the delay of a prescribed time. A timing controller 5, responsive to the output of the circuit 6 delayed by the timer 8, starts the converting operation of the A/D converter 3. Thus, since A/D conversion is started without so long time passing after starting peak hold, no useless hold period is spent. Even when relatively adjacent two pulse signals are inputted, these two pulse signals can be discriminated from each other and the peak values can be detected.

Title: Manufacture of dielectric-isolated semiconductor device
Inventor: YAMAGUCHI YOSHIHIRO
IPC: H01L29/866
Filed: 1988-07-13
Abstract: PURPOSE:To protect wires running across an element isolating region from step-caused disconnections and to enhance device reliability by a method wherein ions are implanted through an insulating film first formed on an isolating region in a dielectric-isolated substrate. CONSTITUTION:On the entire surface of a dielectric-isolated substrate, a silicon oxide film 9 is formed, after which a silicon nitride film 10 is formed. The silicon oxide film 9 is approximately 0.1mums thick, serving as a stopper in the selective etching of the silicon nitride film 10. Next, a photoresist pattern is formed to cover the silicon nitride film 10, and the photoresist pattern serves as a mask in a boron ion implantation process accomplished, with the silicon oxide film 9 retained, for the formation of a p<+>-type layer 11. Next, the entire substrate is subjected to thermal oxidation, which thickens the silicon oxide film 9 where it is not covered by the silicon nitride film 10. A process followed wherein the silicon nitride film 10 is removed, ions are implanted through the silicon oxide film 9, which process results in an n<+>-type layer 12 in an island- shape Si layer 6. Using this method, unnecessary grooves are not produced in an element-isolating region, wires are protected from step-caused disconnections, and devices are improved in reliability.

Abstract: PURPOSE:To prevent the formation of a projection, which brings about the breaking of a wire and the like, on the inner surface of a contact hole by a method wherein the ratio of etching speed of the film to be etched and that of the material of a mask is make different. CONSTITUTION:A wafer is placed in the vacuum container of a reactive ion- etching device, and an insulating film is etched using a resist pattern 5 as a mask. First, in the first process, the ratio of etching speed of the photoresist 5, which is the mask material, and the insulating film which is the film to be etched, is set at 1:5 or above. Then, in the second process, an etching operation is conducted in such a manner that the etching speed of the photoresist 5 which is the mask material and etching speed of the insulating film 4 which is the film to be etched are almost equal. As a result, the part of the photoresist 5 is widely opened, and a funnel-shaped contact bole 9 can be obtained.
