Abstract
PURPOSE: To increase integration density, by using a vertical type transistor in which emitter and collector are reversed from the conventional device as a switching transistor of a current switching logic gate, and operating emitter connection wiring by a common buried layer.
CONSTITUTION: N+-type buried region 2 is formed by diffusion on P-type Si base plate 1, and epitaxial N-type layer 3 is grown on the entire surface. P+-type region 4 sandwiches region 2 and reaches base plate 1, and layer 3 is separated into islands. Next, P-type base regions 511, 51n, 52, 53 are formed by diffusion in separated layer 3. N+-type collector regions 611, 61n, 62, 63 are provided, and thereby transistors Q11, Q1n, Q2, Q3 are formed. These transistors Q11, Q1n, Q2, Q3 are used for vertical type switching. Conventional vertical type transistor is used for power supply. Consequently, each emitter of the switching transistors is connected to each collector of the power supply transistors in region 2, and thereby the degree of integration is increased.
