Abstract:
A method of fabricating a semiconductor device, comprisingdepositing two or more layers of semiconducting material onto a first substrate so as to form a first semiconductor stack; singulating said first semiconductor stack to form a first group of singulated semiconductor stacks, wherein said first group is comprised of at least a first singulated semiconductor stack having an upper semiconducting layer, a lower first substrate layer, and an inner semiconducting layer in contact with said lower first substrate layer; providing a second substrate having a first conductive layer and a first bonding material deposited thereon; selecting said first singulated semiconductor stack from said first group; attaching said upper semiconducting layer of said first singulated semiconductor stack to said first conductive layer of said second substrate so as to form a second semiconductor stack; and removing said first substrate layer and one or more layers of said two or more layers of semiconducting material from said second semiconductor stack so as to form a semiconducting device wherein said inner semiconducting layer is exposed.
