  • Wafer mapping process control with indicator line
    Patent number: 9263397
    Abstract: A method for providing alignment in a die picking process may include aligning a semiconductor wafer based on a reference die, forming an indicator line relative to the reference die by picking a number of dice along a line extending across the wafer, and using the reference line to monitor a position of the picking machine relative to the wafer. A die attach machine may include a control system for automatically implementing such method.
    Type: Grant
