Abstract:
An optical inspection tool used to detect surface defects of a substrate include a chuck for holding a substrate and a lens unit disposed over the chuck. The lens unit includes at least a pair of oblique beam paths therein, wherein light penetrating the beam paths travels without angular deflection. The beam paths take the form of spaces formed through the lens unit, or flat portions formed on a lens within the lens unit. A camera is installed on the lens unit, and the camera converts light passing through the lens unit into an image. Methods of detecting surface defects of the substrate using the inspection tool are also provided.
Abstract:
A heat spreader includes a heat sinking plate and a pressure clip. The heat sinking plate radiates the heat away from a heat source. The pressure clip fixes the heat sinking plate to the heat source. The pressure clip includes a spine (pressing part), one or more ribs and hook parts. The spine is arranged on the heat sinking plate. The one or more ribs extend from the spine and contact the heat source. The hook parts extend from the spine and are supported by the heat source. The pressure clip further includes mounting parts that couple the spine to the hook parts. A bending space is formed between the spine and the heat sinking plate. The heat spreader may be attached to a printed circuit board (PCB) with, e.g., a one-touch method, so that assembling processes of the memory module may be automated.

Abstract:
An apparatus for carrying plural printed circuit boards (PCBs) for semiconductor modules is disclosed. The apparatus comprises a main frame which is formed with an inside space for the PCBs. The main frame includes receivers for supporting one shorter edge of the PCBs. A clamp frame joined to the main frame includes a support plate for the other shorter edge of the PCBs. Movable clamps are elastically connected to the clamp frame so as to push the PCBs by elastic force when the PCBs are loaded into the apparatus. A adjustable mounting such as a slot or holes is provided in the main frame for fasteners joining two frames each other. Therefore, the apparatus can carry the PCBs of different size. The elastic connection between the clamp and the clamp frame is preferably made by slide bars and elastic members. Clamp holes, sub-walls, partition walls, hollow corners, and so forth may be preferably provided for the apparatus.

Abstract:
A method of fabricating a semiconductor device includes preparing a semiconductor wafer having a top surface and a bottom surface. The semiconductor wafer is loaded onto a wafer chuck, and the bottom surface of the loaded semiconductor wafer faces the wafer chuck. A groove is formed in the top surface of the loaded semiconductor wafer by irradiating a second laser onto the top surface, and a reforming region is formed in the loaded semiconductor wafer under the groove by irradiating a first laser through wafer chuck and bottom surface of the semiconductor wafer into a region in which the first laser is focused. The semiconductor wafer is unloaded from the wafer chuck. The bottom surface of the semiconductor wafer is ground to decrease a thickness of the semiconductor wafer. The semiconductor wafer is separated along the groove and the reforming region, thereby forming a plurality of unit chips.
