Patents by Inventor Sun-Ju Kim

Sun-Ju Kim has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Publication number: 20040232938
    Abstract: A test system for a semiconductor device couples the device to the back side of a circuit board, thereby allowing the device to be tested under actual operating conditions while providing adequate clearance around the device to accommodate automatic handling equipment, and also reducing signal delay and distortion. A system in accordance with the present invention includes a circuit board having circuitry adapted to provide an actual operating environment for the semiconductor device, as for example, a low cost mother board for testing memory devices. The device is coupled to the back side of the circuit board through test terminals formed on the back side of the board. An interface board can be used to correct the pin arrangements, which are reversed because they protrude from the back side of the board, and to compensate for the environmental differences caused by use of sockets and additional equipment on the interface board.

  • Patent number: 6819129
    Abstract: A method and apparatus for testing memory devices under actual operating conditions can accommodate non-standard memory devices through the use of an interface board that adapts a non-standard pin configuration to a standard pin configuration on a test substrate. The interface board can include a first surface on which to mount the non-standard device, a pin matching circuit, and a second surface constructed and arranged to couple the pin matching circuit to a standard pin configuration. The interface board can be mounted directly on the test substrate, or coupled to the test substrate through various arrangements of sockets, connection boards, and supports.
