Abstract:
1. A wafer, comprising: a base layer; a first conductive layer portion of a finally constructed wafer located above an upper surface of the base layer; a first trench in the first conductive layer portion; a first insulating material portion of the finally constructed wafer located within the first trench; a second insulating material portion extending horizontally above an upper surface of the first conductive layer portion and connected to the first insulating material portion; a second conductive layer portion above an upper surface of the second insulating material portion; a second trench in the second conductive layer portion; a third insulating material portion within the second trench and on the upper surface of the second insulating material portion; a fourth trench in the first conductive layer portion; and a sixth insulating material portion within the fourth trench, wherein the second insulating material portion above an upper surface of the first layer portion extends from the first insulating material portion to the sixth insulating material portion, wherein: the first insulating material portion is not adhered to the first conductive layer portion; the sixth insulating material portion is not adhered to the first conductive layer portion; and the second insulating material portion is not adhered to the upper surface of the first conductive layer portion.
