Abstract:
1. A method for forming a semiconductor device, comprising: providing a first device layer formed on a first substrate, wherein a conductive top bonding pad layer is formed on the first device layer; providing a continuous second device layer formed on a second substrate, wherein a continuous conductive adhesion layer is formed on the continuous second device layer; bonding the first device layer with the second device layer, where the top bonding pad layer on the first device layer is directly connected with the conductive continuous adhesion layer on the continuous second device layer to electrically couple the first device with the continuous second device layer; removing the second substrate; selectively etching the continuous second device layer and the continuous conductive adhesion layer to form a groove array; and filling up the groove array with an insulation material to form a plurality of second devices insulated with each other.
