Title: Method for joining semiconductor substrates
Inventor: SHIRATORI HARUO
IPC: H01L27/12
Filed: 1991-11-19
Abstract: PURPOSE:To introduce proper internal stress into the firms of substrates for formation of semiconductor elements by bringing two substrates of different temperatures into contact with each other. CONSTITUTION:Two silicon substrates (or wafers) are prepared, and a thermal oxide film 2 is made on each surface. One substrate 1 is put so that the surface may turn up on the surface of the hot plate placed inside a clean room at room temperature, keeping the surface of said hot plate at approximately 60 deg.C. Just as the substrate 1 gets to fit the temperature of the hot plate, another wafer 1 is placed on it, and they are joined temporally. This is put in a furnace to do heat treatment in a nitrogen atmosphere. Hereby, it becomes possible to introduce internal stress of optional magnitude into the film of the substrate manufactured by lamination method.

Filed: 1995-12-20
Abstract: PROBLEM TO BE SOLVED: To obtain the optical receiver over a broad band without deteriorating the S/N by selecting a current of a current source below a current expressed in a specific equation. SOLUTION: A circuit regarded to be equivalent to a current source I with a current ia is connected between ground and a connecting point between an anode of a PIN photo diode D1 being a reception element an input terminal of an amplifier AMP. A polarity of a current of the current source I is positive when a current is directed to an input terminal of the amplifier AMP. In this equivalent circuit, the current ia is expressed as ia=i×(R+RF/A)/(R+1/jωCJ). In this case, the equation expressing a voltage vo at an output terminal of the amplifier AMP by the current (i) of a current source being the equivalent circuit being an input signal is not a function of the frequency. Furthermore, the current ia of the current source I is to be the current expressed by the right-hand side of the equation above or below.  In this case, the frequency characteristic of the photodiode D1 is compensated and improved depending on the current ia of the current source I.
