Title: A progressively renderable outline font and methods of generating, transmitting and rendering the same
Inventor: CHOI HYEONG-IN
IPC: G06K15/02
Filed: 1997-04-09
Granted: 1999-06-01
Abstract: This invention relates to an outline font, particularly to a progressively renderable outline font and methods of generating, transmitting and rendering the same. The objective of this invention is to provide a progressively renderable outline font that can alter the data of the font according to the need. The progressively renderable outline font has the function of appropriately adjusting the display speed of the font and the quality of the font according to the environment and the objectives. For example, in a situation where the hardware has a relatively slow speed and the high quality of the font is not required, a portion of the font data can be displayed. However, in a situation where the hardware has a relatively high speed and the high quality of the font is required, the transmitted data are progressively increased. Therefor, in a restricted environment, the quality of the font can be compromised and a minimum data of the font can be transmitted for display. However, if the environment permits, all data shall be transmitted and the fully quality of the font can be realized.

Title: Ultra-low noise high bandwidth interface circuit for single-photon readout of photodetectors
Inventor: KOZLOWSKI LESTER J
IPC: H01L31/02
Filed: 1998-10-31
Granted: 2000-02-11
Abstract: An ultra-low noise, high gain interface circuit for single-photon readout of known photodetectors from the x-ray to long IR bands at video frame rates. The detector current modulate's a load FET's gate-to-source voltage, which in turn modulates the gate-to-source voltage of a gain FET thereby producing a signal current that is an amplified facsimile of the detector current. The load FET's gate-to-source voltage is connected in the negative feedback loop of a low noise, high gain amplifier. This effectively reduces the resistance seen by the photodetector by the gain of the amplifier thereby reducing the interface circuit's RC time constant by the same amount. Because the amplifier pins the load FET's gate voltage for a given flux level, the load FET's 1/f noise is transferred to the amplifier thereby enabling single-photon readout sensitivity.

Abstract: A method for forming a contact of a semiconductor device, including the steps of forming a pad electrode for a capacitor contact over a semiconductor substrate having an active and inactive regions, forming a first interlayer insulating film over the semiconductor substrate including the pad electrode, forming  a bit line electrode over the interlayer insulating film in the inactive region, forming a protective layer so as to coat the bit line electrode, forming a second interlayer insulating film over the first interlayer insulating film including the protective layer, forming a blocking layer pattern over the second interlayer insulating film so as to overlap the bit line electrode and have a width equal to or larger than the conductive layer pattern, forming a photoresist pattern having an opening over resulting structure, the opening exposing upper surfaces of the second interlayer insulating film and at least one the blocking layer pattern, etching the first and second interlayer insulating films using the photoresistst layer pattern and the blocking layer pattern as a mask, thereby forming a self aligned contact hole exposing upper surfaces of the conductive layer pattern. In accordance with the present invention, a blocking layer pattern which serves as an etching barrier layer for contact hole formation is formed before a photoresist pattern for the contact hole is formed over the blocking layer pattern, thereby preventing bridging between the contact holes. Further, the photoresist pattern may be formed to have a bar type opening or line type opening since the blocking layer pattern is previously formed therebelow, so that the photoresist pattern  formation can be easily done.
