IPC: H03M1/10
Filed: 1983-01-11
Abstract: PURPOSE:To provide a feedback inspecting function for an output current and to simplify constitution by feeding back the output of a counter. CONSTITUTION:The amplitude and frequency of a digital signal from a processor CPU are varied to extract a necessary analog signal by a filter FL1. A comparator CMP compares it with the output signal of an output buffer circuit OBF and sends the result to a counter CNT. The counter CNT varies in counted value by the output based upon the comparison output, and the counted value is supplied to the CPU and also inputted to the 2nd D/A converter D/A2 to vary the amplitude and frequency, so that a necessary analog signal appears at its output. The output buffer circuit OBF controls a transistor to send the output signal to the other input terminal of the comparator CMP. Thus, a digital controller checks the actual analog current output value.

IPC: H01L27/12
Filed: 1989-01-10
Abstract: PURPOSE:To shorten heat-treating time and enable wafers to be adhered to each other by adhering both wafer surfaces which are in hydrophilic state and by performing heat treatment for positively dissipating hydrogen atom of hydroxide group on the surface of the wafer. CONSTITUTION:Two silicon wafers 1 and 2 are subjected to hydrophilic treatment, thus leaving OH group on the application surfaces 1a and 1b. After drying, the surfaces 1a and 1b are adhered. In this state, both silicon wafers 1 and 2 are adsorbed by hydrogen combination. Then, rapid heating treatment is performed to achieve an adhesion strength which is equivalent to that of bulk silicon. With rapid heating, hydrogen atom located on the application interface is dissipated into the wafer directly and is dissipated into air from the opposite surface to the application surface of the wafer in a short time. The remaining oxygen is gradually dissipated into the wafer. Then, each bulk is adhered similarly to bulk combination.
