    • A multi-output collector dot AND circuit wherein a logical AND signal can be formed from a pair of adjacent circuits and another logical AND circuit can also be formed from a pair of circuits spaced from each other. The collector dot AND circuit comprises a plurality of output transistors which are cascade connected to an output electrode of one of a pair of transistors constituting a differential circuit so that an output or outputs different from an output which is used to obtain a logical AND signal together with an output of an adjacent differential circuit are obtained from the one transistor. A number of dummy transistors equal to the number of the output transistors are cascade connected to an output electrode of the other transistor. Further, a constant-current source is connected to the differential circuit such that an electric current which flows from each of the output transistors connected to the one transistor is made equal in magnitude to an electric current which flows from a transistor of the adjacent differential circuit.

    • An insulating layer is formed over a surface of a semiconductor wafer to be the bond substrate and irradiation with accelerated ions is performed, so that an embrittlement region is formed inside the wafer. Next, this semiconductor wafer and a base substrate such as a glass substrate or a semiconductor wafer are attached to each other. Then, the semiconductor wafer is divided at the embrittlement region by heat treatment, whereby an SOI substrate is manufactured in which a semiconductor layer is provided over the base substrate with the insulating layer interposed therebetween. Before this SOI substrate is manufactured, heat treatment is performed on the semiconductor wafer at 1100° C. or higher under a non-oxidizing atmosphere such as an argon gas atmosphere or a mixed atmosphere of an oxygen gas and a nitrogen gas.
