Abstract: A darkening method for the light spot on the matrix display, which is to form an area masking layer above the light spot corresponding to the locations of the light spots when there are the light spot defects on the cover plate of the matrix display, such as on a filter. The structure of the area masking layer, such as the size, transmission rate, density, porosity, thickness distribution, can be determined based on the required darkening level and the device dimensions. Furthermore, after forming the area masking layer, the polarizing film is formed on the filter, so that the polarizing film can also protect the area masking layer.

Title: System for cutting brittle materials
Inventor: NIKITIN DMITRI
IPC: B28D5/00
Filed: 2001-08-02
Granted: 2003-02-21
Abstract: A system for laser cutting brittle materials. In one aspect, the outer perimeter of a base plate of brittle material, which contains therein a workpiece defined by a laser micro-crack cut line, is heated. The heating causes the base plate material to expand away from the micro-crack cut line, therein expanding the interstice between the base plate and the workpiece, releasing the workpiece defined by the micro-crack cut line. Alternatively, a gas emitting tape is positioned under a micro-crack cut line and applies a force against the brittle material along the micro-crack cut line, therein propagating the micro-crack through the thickness of the material and completely separating the brittle material along the micro-crack cut line. Another aspect employs ultrasonic energy to cause breakage of a brittle material along a micro-crack scribe line. Yet another aspect employs the application of high pressure fluid along a micro-crack cut line, therein forcing the material on either side of the cut line apart. Still another aspect embodies the use of two beams of laser energy to create a laser beam incident composite footprint which efficiently creates stress vectors required to split brittle materials.

Filed: 2001-06-15
Granted: 2003-01-11
Abstract: There is provided a nonvolatile semiconductor storage device capable of securing sufficient read accuracy without providing superfluous sense time margin when there are variations in temperature and transistor characteristics. This nonvolatile semiconductor storage device includes a reference cell 2 whose threshold value is preparatorily set to a value between a lower limit of a threshold voltage distribution in a state 0 in which nonvolatile memory cells MC00 through MC12 have a high threshold value and an upper limit of a threshold voltage distribution in a state 1 in which the memory cells have a low threshold value. When the characteristics of the nonvolatile memory cells MC00 through MC12 shift due to the influence of a change in temperature or the like, the characteristics of the reference cell 2 shift so as to follow this characteristic shift. The operation timing of a sense amplifier section 8 in read operation is generated by a control circuit, and the timing of the termination of the sense operation from among the operation timing is determined by timing control circuit (delay circuit delay and AND circuits AN0 and AN1) with the termination of the sense of the reference cell 2.

Title: DRAM manufacturing method
Inventor: YOU JR-SHING
IPC: H01L21/8242
Filed: 2001-10-03
Granted: 2003-03-01
Abstract: A manufacturing method of DRAM having capacitor under bit-line (CUB) is provided. It uses the anisotropic etching to increase the bit-line contact opening, so as to prevent a short circuit between the bit-line and the capacitor top electrode and enlarge the process window of the subsequent photolithography process. This method also uses the NH4OH solution as the wet etching etchant. Because the NH4OH solution has good etching selectivity among amorphous silicon layer, dielectric layer and nitride layer, it doesn't damage the neighboring DRAM or capacitor structures during contact etching. It is helpful for the improvement of the lithography alignment error and the development of CUB DRAM shrinkage.

Title: Method of measuring the movement of an input device and device using the method
Inventor: LIESS MARTIN DIETER
IPC: G06F3/0354
Filed: 2001-11-08
Granted: 2004-03-11
Abstract: An optical input device for an apparatus, generating input signals by moving the device and an object (15) relative to each other and measuring the movement by means of the effects of self-mixing in a diode laser (3, 5) and Doppler shift caused by the movement. For each measuring axis (X, Y, Z) radiation from a diode laser (3, 5) is converged on a window (12) across which the object (15) moves part of the radiation scattered by the object, whose frequency is Doppler-shifted due to the movement, re-enters the laser cavity (20) and causes a change in cavity properties. By measuring such a change, for example by means of a photo diode, information about the movement is obtained. As the input device is small and cheap, it can be used in a number of different consumer apparatus.

Title: Method for protecting phase lock loop in optical data-reading system
Inventor: LAI YI-LIN
IPC: G11B20/00
Filed: 2001-11-09
Granted: 2006-03-21
Abstract: A method for protecting a phase lock loop (PLL) in an optical data-reading system is disclosed. When the lengths of the EFM signal read from the disk contain at least one waveform length longer than 11T and at least one waveform length shorter than 3T, the disclosed method determines that the data read is erroneous, and then maintains the frequency locked by the PLL circuit. Otherwise, the PLL circuit will adjust the locked frequency according to the waveform length of the detected EFM signal so that the system clock frequency can be adjusted based on the locked one. In addition, when the optical system seeks tracks for reading the required data under a constant angular velocity (CAV) modulation mode, the PLL circuit will increase the locked frequency gradually as the pick-up head moves towards the outer tracks of the optical disc, and decrease the locked frequency gradually as the pick-up head moves towards the inner tracks of the optical disc, thereby reducing the time for adjusting the system clock frequency based on the disclosed method.
