Abstract:
1. A method of making a semiconductor package comprising: providing a semiconductor carrier comprising at least a first flexible appendage connected to a body portion; each flexible appendage having a top face and a bottom face; and the body portion having a top face and a bottom face, a first semiconductor device and a second semiconductor device, each having a front face and a back face, the first semiconductor device and the second semiconductor device connected to the first flexible appendage with the front face of each semiconductor device facing the top face of the first flexible appendage, the first semiconductor device further comprises a first alignment key and the second semiconductor device further comprises a second alignment key mateable with the first alignment key, wherein the first alignment key comprises a raised feature spaced a distance from a side edge of the first semiconductor device, wherein the second alignment key comprises a raised feature spaced a distance from a side edge of the second semiconductor device and wherein a second distance is shorter than a first distance, and forming a first fold in the first flexible appendage so that the back face of the first semiconductor device overlies the back face of the second semiconductor device.
