Title: Method of alignment function for recovering  alignment mark
Inventor: JU JR-SHIUN
IPC: H01L21/02
Filed: 1998-10-21
Granted: 2000-05-11
Abstract: A method of alignment function for recovering alignment mark is disclosed in this invention, where a blocking-plate is used as the etching-mask to remove the film on top of the alignment mark of the wafer. An open window and a positioned edge are formed on the blocking-plate and their relative position between the open window and the positioned edge is the same as that of the alignment mark and the positioned edge on the wafer. The positioned edge of the blocking-plate can be aligned with the positioned edge of the wafer such that the open window is aligned with the alignment mark on the wafer when the positioned edge of the blocking-plate is aligned with the positioned edge of the wafer. After the positioned edge of the blocking-plate is aligned with the positioned edge of the wafer, the blocking-plate is used as the etching-mask to partly remove the film exposed by the open window. Therefore, the film no longer shades the alignment mark and the alignment function is really obtained.

Title: Integrated circuit using a back gate voltage for burn-in-operations
Inventor: LEIGH ANTHONY W
IPC: G01R31/28
Filed: 1998-12-23
Granted: 2001-05-16
Abstract: An integrated circuit formed on a semiconductor substrate 10 includes a p-well containing an n-channel field effect transistor 14. Transistor 14 includes a gate conductor 16 on a gate insulator layer 18, and a source region 20 and a drain region 22, consisting of regions doped with n-type impurities. A substrate contact region 24, comprises a region of p-well 12 doped with additional p-type impurities, is formed proximate transistor 14 within p-well 12. Contact region 24 is thus electrically connected to the semiconductor substrate 10. The substrate 10 is connected to a negative back-gate bias voltage during burn-in operations and connected to the supply voltage during normal operations. This back bias voltage prevents latch up conditions during burn-in operations when the integrated circuit is more susceptible to such latch up due to the typically increased supply voltages used.

Title: N-port WDM grating mach-zehnder multiplexer and demultiplexer
Inventor: KECK DONALD BRUCE
IPC: G02B6/293
Filed: 1999-01-16
Granted: 2001-01-21
Abstract: An N-port optical wavelength division multiplexer and demultiplexer includes two evanesent wave couplers connected by N optical paths. Each of the optical paths includes wavelength-selecting elements that are used to select specific wavelength of light. Light signals composed of N wavelengths of light introduced to an exterior port in one of the couplers are spilt substantially equally among all the optical path within the coupler, so that each optical path exiting the coupler includes light of all the wavelengths initially introduced to the coupler. The wavelength selecting elements disposed on each optical path are situated to direct the light in a manner such that light of only the selected wavelengths interferes constructively at a given exterior coupler poat and other wavelengths interfere destructively. Consequently, optical signals composed of N wavelengths may be demultiplexed such that N optical paths carry light having one wavelength. Conversely, N optical paths carrying light signals having only one wavelength can be multiplexed into a signal having wavelength <lambda>1, <lambda>2, ... <lambda>N. The multiplexed signal is then coupled into up to M+O exterior ports.

In order to improve the sealing effect, the frit glass 62 is inserted into the gap at the bonding portion. The groove 64 is formed on the top surface of the sealing wall 63 to prevent the frit glass 62 from intruding into the discharge space.

Title: Positive column AC plasma display
Inventor: WEBER LARRY F
IPC: G09G3/28
Filed: 1999-09-17
Granted: 2001-07-11
Abstract: An AC PDP has a plurality of addressable subpixel sites, each subpixel site including an address electrode positioned on one substrate and first and second sustain electrodes positioned on an opposed substrate. An intersection between the address electrode and the first sustain electrode defines a first discharge site and an intersection between the address electrode and the second electrode defines a second discharge site. A scan driver is active during an address phase, and applies a negative going signal to the first sustain electrode. An address driver applies an address signal to the address electrode which creates a discharge at the first discharge site. As a result, a positive column moves along the address electrode to the second discharge site and causes a discharge thereat which induces a wall voltage at the second discharge site in accordance with a determined subpixel value. A sustain driver applies a sustain signal to both the first sustain electrode and the second sustain electrode and creates a ""ping pong"" action of the wall charge states at the discharge sites and enables the use of positive column light emission in the PDP.

Title: Method for encoding a current frame in a video sequence
Inventor: SETHURAMAN SRIRAM
IPC: H04N7/50
Filed: 2000-01-04
Granted: 2001-11-11
Abstract: For video compression processing, each frame in a video sequence is segmented into one or more different regions, where the macroblocks of each region are to be encoded using the same quantizer value, but the quantizer value can vary between regions in a frame. For example, for the videophone or video-conferencing paradigm of one or more ""talking heads"" in front of a relatively static background, each frame is segmented into a foreground region corresponding to the talking head, a background region corresponding to the static background, and an intervening transition region. An encoding complexity measure is generated for each macroblock of the previous frame using a (e.g., first-order) rate distortion model and the resulting macroblock-level encoding complexities are used to generate an average encoding complexity for each region. These region complexities are then used to select quantizer values for each region in the current frame, e.g., iteratively until the target bit rate for the frame is satisfied to within a specified tolerance range. The selected quantizer values may be modified based on spatial and/or temporal constraints to satisfy spatial requirements of the video compression algorithm and/or provide temporal smoothness in quality, respectively.
