Abstract
A semiconductor device including a polycrystalline silicone resistor which has a resistance of 40 k.OMEGA.-800 k.OMEGA. and which is formed by a polycrystalline silicon film having a specific resistivity of 0.01 .OMEGA..cm-0.1 .OMEGA..cm. The resistor having the above resistance, which has previously been difficult to fabricate, can be fabricated with a high accuracy, so it is very useful for several kinds of semiconductor integrated circuits such as bipolar memory.
