Patent TW-419739-B (TW)
Title: Device and method for preventing settlement of particles on a chemical-mechanical polishing pad
Inventor: LANDERS WILLIAM FRANCIS
IPC: B24B37/10
Filed: 1998-04-13
Granted: 2001-01-21
Abstract: A device located between a polishing pad and a platen of a chemical-mechanical polishing apparatus for preventing settlement of particles on the polishing pad is disclosed. The device has a platen interface layer formed on the platen for interfacing therewith; an active layer formed on the interface layer having at least one vibration module embedded therein; and an energy transport layer formed on the active layer facing the pad. The active layer selectively vibrates regions of the energy transport layer, and the energy transport layer selectively transfers the vibration to the polishing pad. The vibration module is an actuator or an ultrasonic transducer, and is surrounded by a damping material on all sides except a top side contacting the energy transport layer. This provides accentuated vibration to the polishing pad, and attenuated vibration to sides not facing the pad. The energy transport layer includes a wire mesh embedded in bulk material. The wire thickness and density, as well as the weave of the mesh may be varied over different regions of the energy transport layer to provide selective energy transfer from the active layer to the polishing pad. The three layers are removably formed over each other, where the platen interface layer is affixed to the platen by an adhesive.

Title: Method of performing an echo phase offset correction in a multi-carrier demodulation system and echo phase offset correction device for a multi-carrier demodulation system
Inventor: EBERLEIN ERNST
IPC: H04J1/02
Filed: 1998-08-05
Granted: 2000-12-11
Abstract: A method of mapping information onto at least two simultaneous carriers (202, 206, 208) having different frequencies in a multi-carrier modulation system involves the step of controlling respective parameters of the at least two carriers such that the information is differential encoded. A method of de-mapping information based on at least two simultaneous encoded carriers having different frequencies in a multi-carrier demodulation system comprises the step of recovering the information by differential decoding (142) of respective parameters of the at least two carriers. In a method of performing an echo phase offset correction in a multi-carrier demodulation system, phase shifts are differential phase decoded (142) based on a phase difference between simultaneous carriers having different frequencies. An echo phase offset is determined for each decoded phase shift by eliminating (500) phase shift uncertainties corresponding to codeable phase shifts from the decoded phase shift. The echo phase offsets are averaged (520) in order to generate an averaged offset. Finally, each decoded phase shift is corrected (524) based on the averaged offset.

Title: A single-feed circularly polarized printed wide slot antenna with reduced slot size
Inventor: HUANG JIAN-CHIN
IPC: H01Q5/00
Filed: 2000-05-02
Granted: 2001-12-01
Abstract: A new design of a single-feed circularly polarized printed wide slot antenna with reduced slot size is presented. The proposed design is achieved by inserting two narrow metallic strips in orthogonal directions at the slot edge and exciting the slot antenna using a 50-Ω microstrip line with a widened tuning stub. The two metallic strips, with one of them end-loaded a tuning strip, not only provide the required perturbation for the excitation of two orthogonal resonant modes for circular polarization (CP) but also strongly meanders the excited field distributions over the printed slot. The proposed slot antenna can have CP radiation with good impedance matching at a much lowered frequency, compared to the conventional circularly polarized printed slot antenna with the same slot size. Experimental results show that a lowering of about 36% in the center frequency of the CP radiation can be obtained, which also indicates that for a fixed frequency, the proposed CP design can have a slot size only about 40% times that of the conventional printed wide slot antenna.
