Abstract:
Disclosed is a method for forming a polycrystalline silicon film of a polycrystalline silicon thin film transistor. The method includes a step of crystallizing an amorphous silicon film deposited on a glass substrate by irradiating a laser beam onto the amorphous silicon film using a mask pattern. The glass substrate is horizontally moved by a predetermined distance unit corresponding to a translation distance of the mask pattern when the laser beam is irradiated onto the amorphous silicon film through a mask having the mask pattern, thereby growing grains in a circular shape.
Abstract:
An inspecting apparatus for a semiconductor device includes a match plate; a contact module combined with the match plate and including a radiator to radiate heat from the semiconductor device to the outside and a tester to contact the leads of the semiconductor device; and a heat pipe provided in the radiator. The inspecting apparatus performs testing at a constant temperature, regardless of heat from the semiconductor device, by transferring the heat quickly and efficiently, thereby producing more accurate test results. The apparatus also improves productivity and saves expense by removing faulty test results caused by incorrectly identifying a qualified semiconductor device as a defective semiconductor device.
