Title: Hybrid bandpass and baseband delta-sigma modulator
Inventor: MORIN MARC A
IPC: H03M3/02
Filed: 2000-07-24
Granted: 2002-01-11
Abstract: A delta-sigma modulator having a downconverter mixer circuit in the forward path of the modulator circuit and an upconverter mixer in the feedback path of the modulator. The modulator consists of a loop filter having two components, a bandpass filter before the down-converter and a low-pass filter after the down-converter. The mixer circuits can be implemented as single-sideband rejection mixers with in-phase and quadrature paths. In such a modulator, the loop filter component after the quadrature mixer include two low-pass filters, one for the in-phase forward path and another for the quadrature forward path. The feedback also has two paths, which are recombined in the quadrature upconverter located prior to the DAC which produces a real, analog signal to be fed back to the input. Multiple arrangements of this type of modulator can be implemented, including arrangements having multiple intermediate feedback paths to both the baseband low-pass filter and the bandpass loop filter sections.

Title: Method for increasing rounding corner by pull-backed silicon nitride using dry etching in shallow trench isolation processing
Inventor: YU SHIUH-SHENG
IPC: H01L21/76
Filed: 2001-04-06
Granted: 2002-03-21
Abstract: The present invention adds silicon nitride (Si3N4) to conduct an etching step on Si with high selectivity ratio and isotropy after completion of shallow trench etching and this step is used to pull-back the silicon nitride, and also to increase the top corner rounding of the shallow trench in the pull-back process for silicon nitride; and, the pull-backed silicon nitride layer can form a spacer functioning as a buffer layer to protect the insulation corner of the shallow trench. Thus, the method can not only reduce the processing steps of forming polymer spacer and removing the polymer spacer and form the protection of STI corner to prevent the exposure of the STI corner from electrical failure, but also increase the shallow trench top corner rounding, so that after completion of the following trench isolation, it can prevent the trench top corner rounding from generating wrap round.

Title: Chip carrier for removal of residual resin of through trough
Inventor: HUNG JIN-YUAN
IPC: H01L21/00
Filed: 2001-05-14
Granted: 2002-09-21
Abstract: This invention provides a chip carrier for removal of residual resin, in which there are a plural number of independent package units arranged in a matrix pattern previously defined on the surface of the chip carrier. Every package unit provides for the integral formation of a semiconductor package piece from encapsulating a semiconductor chip with the encapsulant. The adjacent package units have a plural number of conical through troughs formed corresponding to many runners formed on predetermined positions of the chip carrier for the molding process. One of the area of the opening end (wide opening part) of a through trough is greater than that of another of the through trough (narrow opening part), so that residual resin formed in the through trough can be pushed out of the wide opening part from the narrow opening part using a stamping knife after the molding process, which also conveniently removes the residual resin in the runners from the surface of the chip carrier. Therefore, the placement of the through troughs can improve the degating process ability for the residual resin and thus ensure that the chip carrier and the solidified package encapsulant are not deformed or damaged during the degating process for the residual resin.

Title: Apparatus and method for drawing three dimensional graphics by converting two dimensional polygon data to three dimensional polygon data
Inventor: MORIWAKI SHOHEI
IPC: G06T15/00
Filed: 2001-06-15
Granted: 2002-12-01
Abstract: The 2D/3D converting unit converts two-dimensional (2D) polygon data to three-dimensional (3D) polygon data by substituting an X-coordinate value of the 2D polygon data for an X-coordinate value of the 3D polygon data, a Y-coordinate value of the 2D polygon data for a Z-coordinate value of the 3D polygon data, and a prescribed value for a Y-coordinate value of the 3D polygon data. The drawing unit draws three-dimensional graphics according to the 3D polygon data generated by the 2D/3D converting unit. Since the 2D/3D converting unit generates the 3D polygon data from the 2D polygon data solely by simple substitutions of the coordinate values, complicated operations are unnecessary for generation of the 3D polygon data. Thus, the three-dimensional graphics drawing apparatus is able to draw the three-dimensional graphics at high speed.
