Abstract:
PURPOSE: A device and a method for the calibration of a biosensor are provided to control the operation point of a biosensor by controlling bias voltage supplied to the biosensor. CONSTITUTION: A device(100) for the calibration of a biosensor comprises a biosensor unit(110), a comparison unit(120), a counter unit(130), and a Digital/Analog converter(140). The biosensor unit changes the conductivity of a semiconductor material. The comparison unit compares the output value from the biosensor unit with reference voltage. The counter unit controls a digital value outputted depending on the output value from the comparison unit. The D/A converter generates bias voltage corresponding to the digital value and supplies the bias voltage to the biosensor unit.

Abstract:
PURPOSE: A novel double HBT-based capacitorless 1t dram cell with Si/SiGE hetero junctions is provided to improve carrier production rate by forming a hetero structure which is divided into the upper part and lower part of a body. CONSTITUTION: A body(110) of a vertical pin type is formed on a substrate(100). The body is formed by using silicon-germanium. The source(120) and drain(130) of a silicon material are formed in right and left sides of the longitudinal direction of the body. A top gate(140) and a bottom gate(150) of a double structure are formed in the top and bottom of the body. A spacer(170) isolates the top gate, the bottom gate, the source and the drain.
Abstract:
PURPOSE: An SBE EDRAM cell transistor which does not have a capacitor is provided to improve a charge holding characteristic by shutting a hole using band offset between a silicon germanium layer and a silicon layer. CONSTITUTION: A silicon dioxide obstacle(100) secludes that a hole which is created by impact ionization gets out. A pair of silicon source-drain layers(200) is formed in the upper end of the silicon dioxide obstacle. A silicon channel layer(300) is formed in order to be contiguous between a pair of silicon source-drain layers. A silicon germanium layer(400) is heterogeneously united in the bottom end of the silicon channel layer and stores the hole which is created by the impact ionization.
Abstract:
PURPOSE: A NOR type memory architecture using non-volatile memory cell is provided to improve the integration degree of memory integration and reduce the error which may occur durin data determining operation though an efficient arrangement of memory cell. CONSTITUTION: A first oxide film is formed on an active pin area of I shape for forming a source/drain area. A second oxide film is formed on the gate area shaped like T. A charge trapping layer is formed between the first oxide film and the second oxide film(S130). The arsenic ion is injected into the source/drain area for doping.
