Patent ID: 8525175

Claim:
An electronic device, comprising: multiple electronic elements each including a semiconductor film; and a field effect element isolation region provided between adjacent ones of the multiple electronic elements, the field effect element isolation region comprising the semiconductor film having a bandgap of 1.95 eV or larger, an insulating film, and an element isolation electrode, the semiconductor film having first portion included in one of the multiple electronic elements and second portion included in the field effect element isolation region so that the semiconductor film is shared by the one of the multiple electronic elements and the field effect element isolation region in each portion, wherein the second portion is extended continuously from the first portion, and the element isolation electrode comprising an electrode which is separated from the semiconductor film of the field effect element isolation region by the insulating film and is applied with a voltage so as to increase a resistance of the semiconductor film of the field effect element isolation region based on an electric field effect, to thereby electrically isolate the multiple electronic elements from one another.
