摘要： A system and method for forming semiconductor devices on more than one surface of a chip is disclosed. A bed is formed with separate portions which connect to a first circuit on a first semiconductor face of a semiconductor chip. A second circuit resides on the opposite face of the semiconductor chip. Providing two circuits on separate faces of a semiconductor chip allows for savings of physical area of the chip. By providing a face-to-face contact with a first circuit, heat generated by the first circuit may be drawn away by the bed. Accordingly, smaller semiconductor chips may be realized without excessive heat generation.

摘要： A power converter apparatus comprises a detection circuit, a control circuit and a time period generating circuit. The detection circuit detects whether a power device is in a short-circuit state. The control circuit sets, when the detection circuit has detected that the power device is in the short-circuit state, the power device in an inoperable state for a predetermined time period, and restores the power device to an operable state after the passing of the predetermined time period. The time period generating circuit defines the predetermined time period for setting the power device in the inoperable state, by measuring a time from the detection of the short-circuit state by the detection circuit.
