Granted: 2002-10-11
Abstract: A kind of apparatus for reducing recess of copper surface in a chemical mechanical polishing (CMP) process is disclosed in the present invention. The invention is suitable for use in a damascene copper process. The invented apparatus includes the followings: a shielding component for separating the external light source; a polishing pad; a polishing platen for carrying and rotating the polishing pad; a polishing header for holding and rotating the wafer so as to make wafer surface contact the polishing pad and conduct the CMP process; and a cleaning apparatus for executing the cleaning process after the CMP process. Thus, the recess phenomenon of copper surface can be reduced and the production yield can be increased. In addition, the present invention also discloses a kind of method for reducing copper surface recess in the CMP process. The invented method is suitable for use in a damascene copper process, in which a shielding component is used to completely block the external light source of the CMP apparatus and the cleaning apparatus so as to conduct the CMP process and the cleaning process. Additionally, the electrochemical reaction in the acidic electrolyte promoted by light source is prevented such that the oxidation-reduction reaction of copper is decreased and the recess phenomenon occurred on the copper surface is reduced.

Title: Analog/digital recording and playback system and related method
Inventor: HOLZMANN PETER
IPC: G11C7/00
Filed: 2001-12-31
Granted: 2003-07-11
Abstract: There is provided an analog/digital recording and playback system capable of recording digital signals to a memory array and playing back digital signals from the memory array in a sampling rate different from the sampling and capturing rate of analog signals sent to the memory array and received from the memory array. This can be accomplished by converting digital signal into analog signal of continuous time in a first sampling rate, or vice versa. Then, in a second sampling rate, the analog sample of analog signal of continuous time is recorded in the memory array, or the analog sample of analog signal of continuous time is captured from the memory array. Such a feature makes the analog record and playback part independent of the digital record and playback part of the system. The advantage of the system is to provide more functions. Because it is able to receive or produce different digital signals with different data rates, the system can be connected to other systems that require different digital formats.

Title: Exhibition structure for hand tool
Inventor: HU HOU-FEI
IPC: B25H3/04
Filed: 2002-10-22
Granted: 2004-05-21
Abstract: The present invention relates to an exhibition structure for hand tool, comprising a body on which fitting blocks are provided at suitable locations, and an exhibited tool set comprised of a tool to which a rotated member is coupled. The rotated member is fit over the fitting blocks with the fitting blocks forming tight-fitting engagement with an inner surface of the rotated member. The tool may selectively drive the rotated member, which is caused to make relative rotation with respect to the body. When the tool applies a torque that is greater than friction between the rotated member and the fitting blocks to the rotated member, the tool drives the rotated member to rotate therewith. When the torque applied to rotated member by the tool is smaller than the friction between the rotated member and the fitting blocks, the rotated member does not rotate. This provides a practical simulation of actually tightening a threaded member. The structure of the present invention is simple, which substantially reduces the manufacturing costs thereof.
