Abstract
PURPOSE:To improve Q of a diode by forming a first conductivity type low resistance impurity diffused region between a second conductivity type impurity diffused region and a second conductivity impurity diffused region for forming the diode in a first conductivity type high resistance epitaxially grown layer. CONSTITUTION:A high resistance N<+> type epitaxially grown layer 2 is formed on an N<+> type semiconductor substrate region 1, and a P<+> type diffused region 4 is formed on the periphery of the layer 2. A P<+> type diffused region 3 which is selectively diffused in the layer 2 and operates as a diode is formed by forming a P-N junction to the layer 2. An N<+> type diffused region 5 is formed in the layer 2 between the region 3 as the diode and the region 4 on the periphery. Thus, a device configuration of high quality of high Q is obtained to improve high frequency characteristic. The breakdown strength of the device can be also improved.
