Granted: 2002-08-11
Abstract: Tracking error detection device of present invention is provided wherein the output of PIN photo diode 1a to 1d generated according to its respective assembly concerned, is transformed by selectors 11a, 11b, and then sent to a phase error detection circuit 13 of last section. The output of said phase error detection circuit 13 is further input into a low-pass filter of last section. In the tracking error detection device thus constructed, phase error detection means and low-pass means for the detection of tracking error signal can be shared with the phase error detection means and low-pass means for the detection of off-set signal. The shared phase error detection means and low-pass means can be used in a time sharing way, so that tracking error signal and off-set signal can be detected. Therefore, in the optical-record reproduction device, the effect of miniaturization and low power consumption of a circuit for the control of tracking a pick-up light can be obtained.

Title: Method of in-line monitoring ion dose
Inventor: WANG CHUN-NAN
IPC: H01L21/265
Filed: 2001-07-25
Granted: 2002-09-01
Abstract: A semiconductor wafer with a photoresist layer atop the semiconductor wafer for an ion implantation process is placed in a vacuum chamber of an ion implanter in a method of in-line monitoring ion dose. The vacuum chamber is then evacuated to a predetermined pressure. A first infrared (IR) beam shoots to the photoresist layer on the semiconductor wafer at a predetermined angle to generate a reflected IR beam shooting to an IR detector. Simultaneously a second IR beam, employed as a background IR beam, is provided to shoot to the IR detector directly. An absorption spectrum of the first IR beam and the reflected IR beam is thus generated. An ion beam is then led to the semiconductor wafer and implanted into portions of the semiconductor wafer not covered by the photoresist layer with a predetermined period. Under normal conditions a stable attenuation (Att) of peaks is observed in portions of the absorption spectrum within a range of a predetermined wavelength after the semiconductor wafer is implanted. Any peak exceeding the stable attenuation observed within the range of the predetermined wavelength indicates an over-implanting in the semiconductor wafer.

Title: Electron beam mask having dummy stripe(s) and lithographic method of manufacturing a semiconductor device using an E-beam mask having at least one defective pattern
Inventor: KI WON-TAI
IPC: H01L21/00
Filed: 2001-10-12
Granted: 2006-10-11
Abstract: An E-beam mask for use in a lithographic process includes a main pattern of stripes of patterned chrome or tungsten formed on a membrane. The stripes of the main pattern are inspected for defects. Dummy stripes corresponding to a defective stripe of the main pattern are formed on the membrane in spare room outside the region bounded by the main pattern. E-beam exposure processes are then carried out using only the non-defective stripes of the main pattern, and the non-defective dummy stripes instead of a defective stripe of the main pattern once the lithographic process has progressed to the defective stripe of the main pattern. When the lithographic process is being used to manufacture DRAM cells, some of the stripes of the main pattern will have the same chrome or tungsten patterns. As long as all of these similar stripes of the main pattern are not defective, then the E-beam processes can be carried out in a sequence using the non-defective stripes of the main pattern only. However, if all of the similar stripes of the main pattern are determined to be defective, a corresponding dummy stripe is produced on the membrane. In this case, the dummy stripe is used in the lithographic process instead of the similar defective stripes of the main pattern.

Title: A tidal power generation method with two-way generation plus pumping at ebb tide
Inventor: YI JWO-HWU
IPC: F03B13/08
Filed: 2002-02-21
Granted: 2004-06-21
Abstract: This patent proposes a tidal power generation method with two-way generation plus pumping at ebb tide period. This method was devised on the assumption that the peak period of electricity consumption coincides with the flood tide period while the off-peak period is concurrent with the ebb tide. At the ebb tide period, water from a tidal power basin is led into the sea to generate electricity. As soon as the water level inside the tidal power basin is equal to that outside the basin, the rest of the water in the tidal power basin is pumped out. By doing so, the power generation capacity at the flood tide period will be increased. This generation method is superior in generating capacity to traditional methods.
