Patent ID: 8900912

Claim:
A method of fabricating a dual-sided camera assembly, the method comprising: fabricating a frontside illuminated (FSI) array of imaging pixels disposed within a first semiconductor die, wherein each FSI imaging pixel includes a photodiode region for accumulating an image charge in response to light incident upon a frontside of the FSI array; fabricating a backside illuminated (BSI) array of imaging pixels disposed within a second semiconductor die, wherein each BSI imaging pixel includes a photodiode region for accumulating an image charge in response to light incident upon a backside of the BSI array; bonding a handling wafer to a frontside of the BSI array; thinning the second semiconductor die at the backside of the BSI array such that a thickness of the second semiconductor die is less than a thickness of the first semiconductor die; and combining the first and second semiconductor dies to form the dual-sided camera assembly.
