A substrate position aligner includes a substrate holding assembly, a plurality of rollers, a rotation mechanism, and a sensor. The substrate holding assembly is configured to hold a substrate in a vertical orientation. The plurality of rollers include at least two idler rollers and a drive roller. Each roller has a point on its perimeter spaced on a common radius from a center of substrate rotation defined within the substrate holding assembly. The sensor is positioned approximately on the common radius and configured to detect the presence of an orientation cut in the substrate when the orientation cut is not orientated within a range between about - 44 degrees and about + 44 degrees from horizontal. A method of aligning a substrate having an orientation cut includes sensing a presence of the orientation cut when the orientation cut is not orientated within the above recited range.

A temperature regulation plate 106 is divided into at least two areas, a heater 408 for applying a temperature load in correspondence with such areas and its control system are divided and controlled independently to set temperatures, and a cooling source is controlled by comparing the measurements from temperature sensors 409 arranged in respective areas for controlling the heater 408 and switching the measurement for calculating the control output sequentially thus reducing variation in in-plane temperature of a wafer due to heating when an electric load is applied. Since consumption and burning of a probe are prevented, highly reliable wafer level burn-in method and apparatus can be provided.

An apparatus for automatically positioning electronic die within temporary packages to enable continuity testing and the like between the die bond pads and the temporary package electrical interconnects is provided. The apparatus includes a robot having a programmable robot arm with a gripper assembly, die and lid feeder stations, a die inverter, and a plurality of cameras or image producers. The cameras take several pictures of the die and temporary packages to precisely align the die bond pads with the temporary package electrical interconnects. A predetermined assembly position is located along a conveyor that conveys a carrier between a first position, corresponding to an inlet, and a second position, corresponding to an outlet. The die, a restraining device and temporary package are assembled at the predetermined assembly position and tested for continuity therebetween. The apparatus further includes a fifth camera which locates the die at a wafer handler. The apparatus has a control mechanism including a microprocessor and associated program routines that selectively control the robot arm (i) to move the gripper assembly to the lid feeder station to pick up a lid, (ii) to move the gripper assembly along with the lid to pick up the die following photographing by the rough die camera, (iii) to move the gripper assembly along with the lid and the die to a position to be photographed by the fine die camera, and (iv) to move the lid and the die to the predetermined assembly position located along the conveyor. The method and apparatus may also be used for disassembly.
摘要:
A workpiece alignment and shifting system for moving circular workpieces from a first inspection station to a second machining station, comprises workpiece holding means for attachment to the face of a disc workpiece to move the latter from one position to another. Robotic means controls the position of the workpiece holding means and is adapted to move in at least two orthogonal directions, both of which are parallel to the plane of the disc when it occupies the first station. The disc is rotated in the inspection station and in the machining station and inspection means determines the position of the geometric centre of the disc as it is rotated. Computing means calculates from data delivered by the inspection means the two shifts required along the orthogonal directions of movement of the robotic means, to move the geometric centre of the disc to a second desired position whose coordinates are known. The computing means includes memory means for storing the said coordinates. The coordinates are those of the centre of rotation of the workpiece holder or chuck in the said second station. The workpiece holding means is vacuum operated. A three axis robot is employed to pick and place disc-like wafers of semi-conductor material for edge grinding, and movement along two of the robot axes, X and Z, is used to control the centering of the wafer on a vacuum chuck in the second grinding station.
