Abstract

PURPOSE:To make an IC output circuit one with pull-up resistance type or one with open drain type, by changing only one mask pattern for ions implantation. CONSTITUTION:The MIS transistor Tre on the side of the load, whose drain is connected to the electrode Vcc and whose gate is connected to the source, is connected to the drain of the MIS transistor Trd on the side of the driving, whose drain is connected to the output terminal out and whose gate is connected to the input terminal and whose source is earthed. In the formation of such output circuit, while the program is written by implanting impurities to the channel of the MIS transistor with regard to the mask ROM in the inside circuit Cin, at the same time corresponding to the outside circuit connected to the output terminal out both the Tre and Trd are made to the enhancement type at first, then by ion implantation the Tre can be made to depression type with pull-up resistance or it may be an open drain type without ion implantation. In this manner two kinds of output circuit can be selectively and simply obtained.
