  • Optimal bank shapes for inkjet printing
    Patent number: 7132788
    Abstract: The shapes of the photo-resist layer “banks” which define pockets for inkjet printing or other patterned processes are optimized to provide a more uniform drying profile for substances which are to be deposited in those pockets and dried therein. Preferably, the shapes of the banks are “mushroom” shaped such that a portion of the photo-resist layer overhangs the exposed lower electrode layer.
    Type: Grant
