Abstract:
A semiconductor integrated circuit device comprising at least three transistor banks over a substrate, the banks being arranged to be substantially parallel to each other in a planar layout of the device, each said bank including a plurality of unit transistors, each unit transistor including a base, an emitter and a collector,wherein in the planar layout of the device, a position of a first one of the transistors is shifted from a position of a second one of the transistors in a direction in which the banks extend, the first and second transistors belonging to first and second ones of the banks, respectively, the second bank being adjacent to the first bank, the second transistor being closer to the first transistor than any other transistor in the bank, wherein in each said bank, the transistors are substantially equally spaced apart from each other, wherein the position of the first transistor is shifted from that of the second transistor by half a distance between horizontally adjacent ones of the transistors belonging to the first bank in the direction in which the banks extend, and wherein two diagonally adjacent ones of the transistors, which belong to the first bank and include the first transistor, and the second transistor are disposed at respective vertices of an equilateral triangle.
