Title: Employing simple testing rule to solve problems of shrinkage of wiring terminal and rounding of corners
Inventor: TU JR-CHIANG
IPC: G01B9/00
Filed: 1998-11-10
Granted: 1999-08-21
Abstract: In order to reduce the number of exposure of electron beam to be minimum required for the following mask preparation, the invention relates to a kind of method to modify a plurality of kinds of optical proximity effect into one mask pattern at a low price. The method is based on few simple testing rules to add the serifs and/or hammerheads to the apex of mask pattern. First, to inspect whether there is overlapped pattern on the next mask. If not, there will be no modification for the apex of pattern. If some overlapped patterns are inspected, it will rapidly scan a specified searching area on the same mask. If it find another stripe within a default distance, the serifs will be added to suitable apex. If no stripe is found, it will scan further second searching area. If it inspects a neighbored stripe, it will add a larger serif. If there is nothing found in the second searching, a hammerhead will be added to suitable wiring terminal. If necessary, the method can be improved utilizing more searching.

Title: Method and system for Flash ROM programming
Inventor: CHEN GUAN-JOU
IPC: G11C16/02
Filed: 1999-06-23
Granted: 2001-03-21
Abstract: Method and system for flash ROM programming is introduced. The system consists of computer, integrated device electronics (IDE) interface, flash controller, flash read-only memory and microprocessor. The flash controller is coupled with host computer via the IDE interface. The flash read-only memory is connected with flash controller. When system inputs the mode of programming flash ROM, the task file applied between the IDE interface and host computer is re-defined by the host computer and compiled by flash controller to let the host computer provide firmware code to write the flash read-only memory through the flash controller. The task file will be back to original setup while the flash read-only memory is completely programmed. The microprocessor pauses the read/write operations from the other sites when the flash read-only memory is at program mode. If the host computer requires several program cycles on the flash read-only memory, the firmware is temporarily stored in a buffer, such as DRAM and then writes the flash read-only memory through the flash controller. Because the software method may use much time of IDE interface and lead delay of the following operation, hardware code is also applied to refresh the firmware code, especially when the firmware codes are huge.

Title: Using a single side band mixer to reject image signals in a wireless station
Inventor: HUGHES SIMON A
IPC: H04B1/28
Filed: 1999-09-29
Granted: 2001-08-01
Abstract: An image signal is removed from a radio frequency (RF) signal received in one of two communication frequency bands, such as the GSM band and the DCS band. The received RF signal is presented to two bandpass filter circuits, each associated with one of the communication bands. Only one of the filter circuits allows the received RF signal to pass. The RF signal then is delivered to a single side band mixer, which converts the RF signal into an intermediate frequency (IF) signal from which information can be obtained. The SSB mixer serves to remove the image signal from the RF signal, regardless of the communication band in which the RF signal lies. As a result, received RF signals do not pass through image reject filters after leaving the bandpass filter circuits.

Title: Apparatus and method for plasma treatment
Inventor: IZAWA MASARU
IPC: H01J37/32
Filed: 2000-09-27
Granted: 2002-07-11
Abstract: The purpose of the present invention is to provide an etching method for obtaining a finely machined shape, especially a vertical shape that has less inner recess for the bore wall when processing the dielectric layer in semiconductor manufacturing. For O, F or N radical incident quantity that is excessive at the initial stage of etching, by controlling a gas flow rate or the consumption quantity of O, F and N in an inner wall face with etching time, excessive O, F and N are suppressed. In addition, based on a plasma measurement result in etching, the flow rate or consumption quantity is controlled to obtain a stably etched shape. By maintaining the etching rate and selectivity, inner recess for the bore wall can be reduced in processing a hole of the dielectric layer and an organic film such that it becomes easy to manufacture more fine semiconductor device.
