Patent TW-476227-B (TW)
Title: Optoelectronic devices containing highly transparent non-metallic cathodes
Inventor: THOMPSON MARK E
IPC: H05B33/00
Filed: 1999-04-26
Granted: 2002-02-11
Abstract: A novel class of low reflectivity, high transparency, non-metallic cathodes useful for a wide range of electrically active, transparent organic devices are disclosed. As a representative embodiment, the highly transparent non-metallic cathode of an OLED employs a thin film of copper phthalocyanine (CuPc) capped with a film of low-power, radio-frequency sputtered indium-tin-oxide (ITO). The CuPc prevents damage to the underlying organic layers during the ITO sputtering process. Due to the low reflectivity of the non-metallic cathode, a non-antireflection-coated, non-metallic-cathode-containing TOLED is disclosed that is 85% transmissive in the visible, emitting nearly identical amounts of light in the forward and back-scattered directions. The performance of the non-metallic-cathode-containing TOLED is found to be comparable to that of TOLEDs employing a more reflective and absorptive cathode consisting of a semi-transparent thin film of Mg:Ag capped with ITO. The present invention is further directed toward novel OLEDs in which the highly transparent non-metallic cathodes may be used in OLEDs comprised of a charge carrier layer containing a compound having molecules that have at least one electron transporting moiety and at least one hole transporting moiety, OLEDs comprised of an emissive layer containing an azlactone-related dopant, OLEDs comprised of an emissive layer containing a phosphorescent dopant compound, or OLEDs comprised of a hole transporting layer containing a glassy organic hole transporting material comprised of a compound having a symmetric molecular structure.

Title: CMOS pulse contraction delay element with deep sub-nanosecond resolution
Inventor: CHEN BO-CHI
IPC: H03K5/159
Filed: 1998-12-31
Granted: 2001-04-11
Abstract: A novel CMOS pulse contraction delay element with deep sub-nanosecond resolution is provided, which is suitable for the time-to-digital converter (hereinafter abbreviated as TDC). The present invention completely changes the pulse-reduced delay element circuit in the conventional TDC which requires an external bias to change the pulse contraction capability, such that the element is able to control its pulse contraction capability simply by changing the size ratio or driving capability of the adjacent elements, thereby not only greatly simplifying the circuit but also accurately designing the pulse contraction capability for each element. The single shot error of the TDC made by the elements is able to accurately reach the order of 10 pico-second. Moreover, the power consumption is low and no bias adjustment and continuous calibration are required. The element is not sensible to the variance of the supplied voltage and temperature. Therefore, the precision and stability of the TDC can be assured under any circumstance.

Granted: 2001-11-21
Abstract: This invention provides an easy dual damascene method for producing a semiconductor device having an insulative interlayer such as that formed of a fluorocarbon film. Subsequent to forming an insulative film such as a SiO2 film (3) on a substrate (2), the SiO2 film (3) is etched to form a via hole (31), and an upper insulative film such as a CF film (4) is formed on the upper surface of the SiO2 film (3). After the CF film is produced via a plasma process for embedding a film forming material of poor characteristics, such as a C6F6 gas, the CF film is prevented to deposit in the via hole (31) on one hand, and is formed into the CF film (4) on the SiO2 film (3) on the other hand. Afterwards, the CF film (4) is etched to form a grooved part (41). The grooved part (41) and the via hole (31) are thereby formed easily as an integral body having a dual damascene.

Title: Method to cancel echo
Inventor: CHEN YUE-JANG
IPC: H04M9/08
Filed: 2000-02-25
Granted: 2001-10-21
Abstract: A method to cancel echo is disclosed. First maintain the threshold value signal and medium value signal above a preset level. Then judge whether the difference between the echo signal (I) and the medium value signal (I-1) is larger than the positive threshold value or less than the negative threshold value. If the difference is larger than the positive threshold value, increase the level of the medium value signal (I), and the threshold signal (I) rises with the first speed faster than the rising speed of the medium value signal (I). If the difference is less than the negative threshold value, reduce the level of the medium value signal (I), and the threshold value signal (I) diminishes with the second speed faster than the diminishing speed of the medium value signal (I-1). Finally, if the difference between the echo signal (I) and the medium signal (I-1) is not greater than the positive threshold value and not less than the negative threshold value, that means the echo signal is within the normal range, it is not necessary to proceed any actions to adjust the threshold value. Said (I) represents the current state of the corresponding signal, and (I-1) represents the previous state of the corresponding signal. The present invention can cancel the echo even if the echo is large.

Title: A compact microstrip antenna with a slotted ground plane
Inventor: WENG JIN-LU
IPC: H01Q5/00
Filed: 2000-05-02
Granted: 2001-09-21
Abstract: A novel design of a compact microstrip antenna with a slotted ground plane is proposed. By embedding a pair of narrow slots in the ground plane, both the excited surface current distributions on the ground plane and radiating patch are strongly perturbed and concentrated towards the centers of the ground plane and radiating patch. This behavior causes lengthening of the equivalent excited patch surface current paths and results in the lowering of the resonant frequency, which corresponds to a reduced antenna size at a fixed frequency. From experimental results of a constructed prototype, it shows that, compared to a corresponding regular microstrip antenna, the antenna size can be reduced by about 39%, and moreover, the antenna gain can be increased by about 1.5 dBi and the antenna bandwidth can be enhanced by about 20%.

Title: Active-matrix type liquid crystal display device and method of compensating for defective pixel
Inventor: BAN ATSUSHI
IPC: G01R31/00
Filed: 1996-08-13
Granted: 2002-12-21
Abstract: Auxiliary lines are formed under pixel electrodes so as to be parallel to signal lines. The auxiliary lines are connected to the signal lines at one point for each pixel. This permits a voltage to be kept applying to a signal line even if a disconnection defect occurs in the signal line by making a circuit around a disconnected portion by the auxiliary line. Moreover, if a leakage defect occurs at a crossing point between the scanning line and the signal line, the signal line would be cut off on both sides of the scanning line. This also permits a voltage to be kept applying to the signal line by the auxiliary line. Furthermore, by setting the auxiliary lines narrower than the signal line, a reduction in aperture ratio can be suppressed, and by adopting the auxiliary lines made of a transparent electrically conductive material such as ITO, etc., it is possible to prevent the reduction in aperture ratio due to the auxiliary lines. The arrangement permits a generation of a line-shaped defect due to disconnection to be prevented while improving an aperture ratio of the pixel with ease.
