20090280646MANUFACTURING METHOD FOR MICRO-TRANSFORMERS - A micro-transformer manufacturing method is provided, which can improve throughput, prevent a crack from entering an insulating film between coils, and manufacture the micro-transformer without using a mask material having a high selection ratio. An insulating film is deposited on the whole face of a semiconductor substrate having an impurity-diffused region. This insulating film is partially removed to form a first opening and a second opening. A primary coil is formed such that a center pad contacts the impurity-diffused region through the first opening. A thin insulating film is deposited on the primary coil. An insulator material having a secondary coil formed thereon is adhered onto the insulating film on the primary coil by adhesive tape. The insulator material is sized to not cover both a pad, connected with the center pad of the primary coil through the impurity-diffused region, and an outer-end pad of the primary coil.11-12-2009
