Abstract:
A system for electrically isolating a portion of a wafer comprising:a first wafer having a first side and an opposing second side; a first conductor extending through said first wafer from said first side to said second side; a first conductor insulating layer extending through said first wafer, said first conductor insulating layer engaging said first conductor and disposed between said first conductor and material of said first wafer, said first conductor insulating layer being formed of dielectric material; and a first outer insulating layer extending through said first wafer from said first side to said second side and spaced from said first conductor insulating layer such that said first outer insulating layer at least partially electrically isolates said first conductor from portions of the first wafer located outside said first outer insulating layer, said first outer insulating layer being formed of dielectric material.
