Title: Operational amplifier for driving integrated circuit of liquid crystal display
Inventor: YEN CHEN-SONG
IPC: G09G3/36
Filed: 2001-08-10
Granted: 2002-11-11
Abstract: The present invention provides an operational amplifier comprising an input stage circuit for receiving an input signal and a driving stage circuit for coupling to one output terminal of the input stage circuit. The driving stage circuit is used to provide a current to a loading. According a voltage from the output signal of the driving stage circuit, a feedback compensation means is for selecting one of the feedback compensation circuits as the feedback compensation path for the driving stage circuit. Furthermore, a circuit-controlling circuit controls the bias voltage of the driving stage circuit according the input signal of the input stage circuit and the output signal of the driving stage circuit. When the input signal is much than the output signal, a current provided by a power supply flows into the loading in the driving stage circuit. When the input signal is less than the output signal, a current flows from the loading to ground through the driving stage circuit. When the input signal is equal to the output signal, there is no current to the loading. The present invention provides the current-controlling circuit and the feedback compensation means for reducing the space of the operational amplifier and the consumption of the electric power.

IPC: H01L21/28
Filed: 2002-05-02
Granted: 2005-12-01
Abstract: A method for forming an etching mask structure on a substrate comprises etching the substrate, laterally expanding the etching mask structure, and depositing a self-aligned metal layer that is aligned to the originally masked area. The etching can be isotropic or anisotropic. The self-aligned metal layer can be distanced from the original etching masked area based on the extent of the intentionally laterally expanded etching mask layer. Following metal deposition, the initial mask structure can be removed, thus lifting off the metal atop it. The etching mask structure can be a resist and can be formed using conventional photolithography materials and techniques and can have nearly vertical sidewalls. The lateral extension can include a silylation technique of the etching mask layer following etching. The above method can be utilized to form bipolar, hetero-bipolar, or field effect transistors.

Abstract: A method and system for fast on-line electro-optical detection of wafer defects featuring illuminating with a short light pulse from a repetitively pulsed laser, a field of view of an electro-optical camera system having microscopy optics, and imaging a moving wafer, on to a focal plane assembly optically forming a surface of photo-detectors at the focal plane of the optical imaging system, formed from six detector ensembles, each ensemble including an array of four two-dimensional CCD matrix photo-detectors, whereby each two-dimensional CCD matrix photo-detector produces an electronic image of a large matrix of two million pixels, such that the simultaneously created images from the different CCD matrix detectors are processed in parallel using conventional image processing techniques, for comparing the imaged field of view with another field of view serving as a reference, in order to find differences in corresponding pixels, indicative of the presence of a wafer die defect. The continuously moving wafer is illuminated by a laser pulse of duration, for example, ten nanoseconds, significantly shorter than the pixel dwell time, that there is effectively no image smear during the wafer motion. The laser pulse has sufficient energy and brightness to impart the necessary illumination to each sequentially inspected field of view required for creating an image of the inspected wafer die. Parallel processing of a focal plane assembly including twenty-four CCD matrix photo-detectors pro-vides an overall pixel processing data rate of nearly 1.5 giga-pixels per second. The wafer inspection system operates essentially at 100% efficiency, whereby, the laser pulse rate of 30 pulses per second is synchronized with the frame speed of 30 frames per second of each CCD matrix photo-detector, and the wafer is moved at a linear speed such that the distance between successive fields of view is covered in 1/30 of a second.
