ABSTRACT:
An insulating transformer includes a semiconductor substrate, an insulating substrate, a primary winding provided on one of the semiconductor substrate and the insulating substrate, a secondary winding provided on other of the semiconductor substrate and the insulating substrate, and an insulating spacer layer provided in between the semiconductor substrate and the insulating substrate for insulating and separating the primary winding and the secondary winding. The primary winding and the secondary winding are disposed to face each other. The insulating spacer layer maintains a constant interval between the semiconductor substrate and the insulating substrate.
