Patent TW-474067-B (TW)
Title: A signal processing circuit
Inventor: MAY MICHAEL R
IPC: H03M7/36
Filed: 2000-08-28
Granted: 2002-01-21
Abstract: An analog-to-digital or digital-to-analog system contains a converter (706). The converter is supplied with a clock signal (CLKI) at a frequency fs derived from a crystal of a frequency fs/N. The frequency fs is derived from the fs/N crystal frequency by using an edge-triggered clock multiplier 705 which multiplies the crystal frequency by the factor N. The result is a low-cost clock solution that incorporates clock jitter around a localized frequency of fs/N. Sigma delta processing circuitry (702) is then used to place a null (e.g., low gain area) in the quantization noise at the same frequency where clock jitter noise is high in order to cancel the adverse cumulative effects of these two types of noise.

Title: Sealed ferroelectric memory cell
Inventor: LUNG SHIANG-LAN
IPC: H01L27/11
Filed: 2000-10-02
Granted: 2001-11-21
Abstract: This invention provides sealed ferroelectric memory cell. A sealing layer is formed on the exposed surface of gate stack layer containing gate dielectric layer, bottom electrode, ferroelectric layer and top electrode to cover and seal the gate stack layer. An outer electrode is formed on the sealing layer to be used for determining the direction of polarization of the ferroelectric layer and thus storing data by applying electric field. Because the gate stack layer is fully sealed by the sealing layer, the stored charges will not be lost to incur leakage current, the completeness of data can be retained and the storage time of data can be extended.

Title: Multiple exposure process for formation of dense rectangular arrays
Inventor: BUKOFSKY SCOTT J
IPC: G03F1/00
Filed: 2001-04-27
Granted: 2002-07-21
Abstract: A method for exposing a workpiece in a dual exposure step-and-repeat process starts by forming a design for a reticle mask. Deconstruct the design for the reticle mask by removing a set(s) of the features that are juxtaposed to form hollow polygonally-shaped clusters with a gap in the center. Form unexposed resist on the workpiece. Load the workpiece and the reticle mask into the stepper. Expose the workpiece through the reticle mask. Reposition the workpiece by a nanostep. Then expose the workpiece through the reticle mask after the repositioning. Test whether the plural exposure process is finished. If the result of the lest is NO the process loops back to repeat some of the above steps. Otherwise the process has been completed. An overlay mark is produced by plural exposures of a single mark. A dead zone is provided surrounding an array region in which printing occurs subsequent to exposure in an original exposure. Alternatively, the workpiece can be fully exposed first by stepping a series of full steps, then going back to the starting position, making a nanostep to reset the starting position and re-exposing from the reset starting position in the same way with full steps from the nanostepped position. The clusters may be in the shape of a hexagon or a diamond.

Title: Method of fabricating a stringerless flash memory
Inventor: CHEN CHIEN-WEI
IPC: H01L21/8246
Filed: 2001-08-30
Granted: 2002-09-11
Abstract: A semiconductor substrate is provided. A number of rows of layer stacks are formed on the semiconductor substrate with a shallow trench positioned between two adjacent layer stacks. Each layer stack is a polysilicon layer and a sacrificial layer and has two side walls. Each side wall of the layer stack intersects the bottom of the shallow trench at an angle of approximately 90 degrees. A HDPCVD silicon oxide layer is deposited to cover the layer stacks and the shallow trenches followed by a planarization process to remove portions of the HDPCVD silicon oxide layer to expose the sacrificial layer. Then, the sacrificial layer is removed. An insulating layer, a word line layer, and a photoresist layer are formed on the polysilicon layer, respectively. The photoresist layer is patterned so as to define a position for forming a word line. A first dry etching process is performed to remove portions of the word line layer not covered by the photoresist layer with a first selectivity of polysilicon to silicon oxide. Following that, a second dry etching process is performed to etch portions of the insulating layer not covered by the photoresist layer with a second selectivity of polysilicon to silicon oxide. Finally, a third dry etching process is performed to etch the polysilicon layer with a third selectivity of polysilicon to silicon oxide, forming a T-shape side view for the remaining polysilicon layer.
