Title: Method for performing a focus step in photolithography process
Inventor: LAI FENG-LIANG
IPC: H01L21/027
Filed: 1999-11-16
Granted: 2001-02-21
Abstract: The present invention discloses a method for performing a focus step in photolithography process, which comprises the following steps: moving the semiconductor chip by a chip carrier, after the stepper completes exposing an exposure region of the semiconductor chip and before performing an exposure step to the next exposure region, so that the laser beam spot of the focus system of the stepper is illuminated on the side of the alignment mark thereby performing a focus step. When the focus step is completed to determine the optimal focal length, the semiconductor chip is moved by the chip carrier again, so that the light source of the stepper exposes the next exposure region. Then, the semiconductor chip is moved by the chip carrier again to make the laser beam spot of the focus system of the stepper be illuminated on the side of the alignment mark again to perform a focus step. These steps are repeated until the whole chip is exposed.

Title: Method to reduce the deviation of optical proximity effect in the photolithography process
Inventor: WANG LI-MING
IPC: G03F7/20
Filed: 2000-02-15
Granted: 2001-06-16
Abstract: The present invention is a method to reduce the deviation of optical proximity effect applied in the photolithography process, wherein the deviation of optical proximity effect on the semiconductor substrate due to uneven thickness or reflectance can be eliminated. The feature of the method is to adjust the exposure parameter setting in each exposure step (e.g. numerical aperture, partial coherence, exposure energy, depth of focus, etc.) according to the deviation of the optical proximity effect of each exposing region on the semiconductor substrate. Thereby the deviation of optical proximity effect of the exposure region can be compensated and a fixed and uniform result of optical proximity effect can be obtained. The chip obtained in this way will have the same quality and performance control.

Title: Phosphor and fluorescent display device
Inventor: NAMIKI AKIO
IPC: H01J31/15
Filed: 2000-10-03
Granted: 2001-11-21
Abstract: The present invention is a phosphor body which can realize both a long life and a white luminescence while suppressing the use of an S-base phosphor to minimum. This phosphor is a white-luminescent one prepared by mixing a blue-luminescent phosphor represented by ZnGa2O4:Li, P and a yellow- luminescent phosphor represented by (Zn, Cd)S:Ag, Cl in a ratio of 4:1. Since, at the same voltage, the luminance of the yellow-luminescent one represented by (Zn, Cd)S:Ag, Cl is higher than that obtained by the blue-luminescent phosphor represented by ZnGa2O4:Li, P, the mixing ratio may be low. In comparison with a conventional phosphor containing considerable amounts of Cd, S-base phosphors, a phosphor of the invention exhibits a relatively small bad effects due to these substances. When the emission characteristics of a phosphor of the invention is compared with that of a conventional one, it is found that a phosphor of the present invention has a higher residual emission rate and a longer life than a conventional one.

Title: Method for replacing a device driver during system operation
Inventor: ASSELIN ALBERT ANDRE
IPC: G06F9/44
Filed: 2000-12-29
Granted: 2003-01-01
Abstract: A method and system for replacing a device driver during system operation provides for hot-swapping device drivers without shutting down a device driver stack. Particularly useful with file system and file storage devices, the method and system utilize a shell device driver that replaces the physical device driver's entry point interface. The shell device driver has a device driver side interface that calls the physical device driver in response to operating system requests. When an update of the physical device driver is requested, either by an operating system utility or a special upgrade application, the shell device driver receives an update indication. The shell device driver can then finish required tasks, uncouple and unload the existing physical device driver and couple to the new device driver without disrupting the operating system device interface.

Title: Data processor and data processing system
Inventor: MURAKAMI YASUYUKI
IPC: G06F9/38
Filed: 2001-02-16
Granted: 2002-12-21
Abstract: The present invention aims to simplify the structure of command prefetching for program processing by allocating commands on the main linear continuous addresses of loop command that is almost non-existing. The bus controller (4) for controlling the bus of the external memory (2) consists of several command buffers (Buf4, Buf8, BufC), several flags (Flg4, Flg8, FlgC), and a buffer control circuit (30), wherein each command buffer has its own unique flag. The buffer control circuit allocates one characteristic value obtained from one of the several lower bits of the command addresses into each command buffer and, by using the address following a specific command fetching address as a base, prefetches the command into the command buffer corresponding to the lower bits in accordance with the address sequence. In comparison with the application of the control mechanism formed by address labels of flash memory and the application of read/write index control mechanism formed by counters of first-in-first-out (FIFO) buffer, the application of the command prefetching structure is more efficient in accomplishing the required simplification.
