Title: Wafer fixing machine
Inventor: TANG JIAN-JUNG
IPC: H01L21/68
Filed: 2000-12-22
Granted: 2001-10-21
Abstract: A wafer fixing machine is disclosed, which is formed of an O-ring, insulation base, RF plate, plural screws and a ceramic electrostatic chuck (ESC), wherein the O-ring is fixed on a circular groove of the insulation base, the RF plate is located on the insulation base and is inside the circular groove, as for RF plate, it is located on the insulation plate and the RF plate to wrap the RF plate. Since the ceramic-ESC covers the RF plate to prevent the RF plate from exposing, and with the blocking effect of the O-ring, the plasma particles won't enter the machine to cause an electric arc. Therefore, there won't be high temperature inside the machine, and the phenomena of non-uniform wafer temperature and different etch rate are prevented, thereby the uniformity and the yield rate of the wafer is further increased, and also the lifetime of the wafer fixing machine can be elongated.

Title: An integrated circuit package
Inventor: COHN CHARLES
IPC: H01L23/50
Filed: 2001-07-23
Granted: 2002-08-11
Abstract: An integrated circuit package where the integrated circuit chip is mounted on a conductive slug and electrically coupled to the slug. Besides acting as a heat spreader, the conductive slug may also function as a ground plane. This reduces the need for additional conductive layers and plated through hole connections for forming connections to, for example, ground. As a result, the conductive paths in the internal ground planes are not necessarily cut off by the plated through holes used for interconnecting ground connections thus avoiding some of the electrical performance degradation suffered by prior techniques. In addition, the invention allows more signals to be added and/or the size of the integrated circuit chip to be reduced to enhance electrical performance. It is to be understood that both the foregoing general description and the following detailed description are exemplary, but are not restrictive, of the invention.
