Abstract: The present invention minimizes parasitic inductance at the time of packaging a semiconductor that requires high efficiency and high-speed switching driving. In implementing a semiconductor package composed of one or more switching devices and one or more diode devices, the present invention provides a flip-stack structure in which a switching device is mounted on an insulating substrate or a metal frame, a flat metal is bonded onto the switching device, and a diode device is flipped and stacked on the flat metal, and accordingly, the flat metal with a large area is used for connection between the devices and between the devices and the insulating substrate, thereby minimizing parasitic inductance generated at a time of semiconductor packaging and automating the entire process of the semiconductor packaging.

Abstract: The apparatus for ESD test includes a micro-controller unit client, a low voltage supply configured to output a low voltage on the basis of control by the micro-controller unit, a high voltage supply configured to output a high voltage on the basis of control by the micro-controller unit, and an ESD generator configured to generate an ESD voltage for an ESD test of a device under test (DUT) by using the low voltage and the high voltage, on the basis of control by the micro-controller unit. The ESD generator is a semiconductor integrated circuit module where a charging semiconductor switch, a discharging semiconductor switch, a switch driving block controlling a switching operation of each of the charging semiconductor switch and the discharging semiconductor switch, and a plurality of passive elements connected to the charging semiconductor switch and the discharging semiconductor switch are implemented as package, for generating the ESD voltage.
