Abstract: A semiconductor package, a redistribution structure and a method for forming the same are provided. The redistribution structure for coupling an encapsulated die is provided, the redistribution structure includes a conductive pattern disposed over and electrically coupled to the encapsulated die. The conductive pattern extends beyond an edge of the encapsulated die along a first extending direction which intersects a second extending direction of the edge of the encapsulated die by an angle in a top view, and an impurity concentration of sulfur in the conductive pattern is less than about 0.1 ppm.

Abstract: A method of reducing manufacturing defects of semiconductor wafers during a back-grinding process. The method includes receiving a semiconductor wafer on a chuck table, wherein said chuck table has a surface upon which a front side of the wafer is placed, and wherein said chuck table has one or more holes in surface and one or more sensors placed in said one or more holes. The method further includes grinding at least a portion of a back side of the semiconductor wafer. The method further includes monitoring a parameter, while grinding, measured by the one or more sensors and adjusting the grinding based at least on the monitored parameter.

Abstract: In a system or method for controlling wafer back-grinding, a chuck table has a surface for supporting a semiconductor wafer during a back-grinding process, one or more holes in the surface, and one or more sensors disposed in the one or more holes for monitoring a parameter during back-grinding. A computer-implemented process control tool is coupled to receive one or mote outputs from the one or more sensors and control the back-grinding process based on the received one or more outputs.
