Patent ID: 7645635

Claim:
A method for packaging a semiconductor die, comprising: providing a frame structure including a plurality of frames, each frame of the plurality of frames including an aperture extending therethrough between an upper surface and a lower surface of the frame structure and each aperture having at least an inverted step extending peripherally thereabout and at least one upper step extending peripherally thereabout; securing a semiconductor die in the aperture of at least one frame of the plurality of frames with an active surface of the semiconductor die substantially abutting a surface of the at least an inverted step and a substantial portion of lateral sides thereof received within the aperture; securing a window in the aperture of the at least one frame with a surface of the window substantially abutting a surface of the at least one upper step; and cutting the frame structure between adjacent frames to singulate the at least one frame with the semiconductor die and the window secured therein and provide a skirt at a lower extent of the singulated at least one frame extending at least partially over a lateral side of the semiconductor die to form a semiconductor die package.
