Abstract:
Provided are a rotational PCR apparatus, a PCR chip for the same and a rotational PCR method using the same.The disclosed rotational PCR apparatus includes: a PCR chip where PCR is performed; a rotating means connected to the PCR chip and rotating the PCR chip; and a temperature zone forming means spaced apart from the PCR chip, capable of applying thermal energy to the PCR chip and allowing the rotating PCR chip to pass through different temperature zones. The rotational PCR apparatus and method allow performance of PCR with wanted temperature condition and cycles by rotating the chip containing the target substance. Accordingly, a high-efficiency PCR process may be accomplished at low cost. Further, since the target substance can be effectively separated and purified utilizing the centrifugal force resulting from the rotating platform, separation and purification may be achieved economically without requiring additional equipments.
Abstract:
An asymmetrically grounded susceptor used in a plasma processing chamber for chemical vapor deposition onto large rectangular panels supported on and grounded by the susceptor. A plurality of grounding straps are connected between the periphery of the susceptor to the grounded vacuum chamber to shorten the grounding paths for RF electrons. Flexible straps allow the susceptor to vertically move. The straps provide a conductance to ground which is asymmetric around the periphery. The straps may be evenly spaced but have different thicknesses or different shapes or be removed from available grounding point and hence provide different RF conductances. The asymmetry is selected to improve the deposition uniformity and other qualities of the PECVD deposited film.

Abstract:
A high voltage power supply is provided. The high voltage power supply includes a soft-start circuit unit which outputs a natural voltage that decreases exponentially as time elapses and converts the natural voltage into a forced voltage having a predetermined scale if an enable signal is applied, a controller which compares the natural voltage output from the soft-start circuit unit with a reference voltage and outputs a control signal, and a converting unit which delays outputting a final voltage during a first predetermined time period and outputs the final voltage, which gradually increases as time elapses according to the control signal.
Abstract:
A system and method for handing off from a first network to a second network. A determination may be made as to whether an accessible base station of the second network is located in the vicinity of a user equipment based on information on a current location of the user equipment in the first network. An activation message may be generated with a first telephone number as a caller number when an accessible base station of the second network is located in the vicinity of the user equipment based on the determination result. The activation message indicates an initiation of a search for an accessible base station of the second network, and an accessible base station of the second network may be searched for when the activation message with the first telephone number is received. A handoff from the first network to the second network may then be executed when the accessible base station of the second network is located.
Abstract:
Systems and methods for improving robust layer separation during the separation process of an imprint lithography process are described. Included are methods of matching strains between a substrate to be imprinted and the template, varying or modifying the forces applied to the template and/or the substrate during separation, or varying or modifying the kinetics of the separation process.
Abstract:
A semiconductor device includes a plurality of parallel-trenches that are parallel to each other, a plurality of intersect-trenches that are parallel to each other, a plurality of active regions that are confined by the parallel-trenches and the intersect-trenches, a plurality of lower conductive lines that cross the active regions, a plurality of upper conductive lines that are parallel to each other, that cross the lower conductive lines, and that cross over the active regions, and data storage elements connected to the active regions. Each of the parallel-trenches and the intersect-trenches is a straight line. The parallel-trenches cross the upper conductive lines and form a first acute angle with the upper conductive lines. The intersect-trenches cross the parallel-trenches and form a second acute angle with the parallel-trenches.
