Patent ID: 8796822

Claim:
A stacked semiconductor device comprising: a first semiconductor device having a first major surface and a second major surface opposite the first major surface, the first major surface of the first semiconductor device having: active circuitry; a beveled edge on at least one edge of the first semiconductor device; and a probe pad which extends onto the beveled edge of the first semiconductor device; and a second semiconductor device having a first major surface and a second major surface opposite the first major surface, the first major surface of the second semiconductor device having: active circuitry; a beveled edge on at least one edge of the second semiconductor device; and a probe pad which extends onto the beveled edge of the second semiconductor device; wherein: the first major surface of the first semiconductor device faces the first major surface of the second semiconductor device such that the first major surfaces of the first and second semiconductor devices are between the second major surfaces of the first and second semiconductor devices and wherein the beveled edge of the first semiconductor device faces the beveled edge of the second semiconductor device such that a first opening is formed between the beveled edges of the first and second semiconductor devices on a first vertical side of the stacked semiconductor device.
