Abstract
A connector block formed in a semiconductor chip to provide all contacts on the same side of the chip. The connector block is preferably formed by driving a slow diffusing dopant deep into the chip from both sides until the diffused dopant overlaps in the middle of the chip. The connector block is metalized with a top contact and connected to circuits. The bottom of the connector block is metallized and connected to other bottom side contacts which, in turn may be connected to circuits. This arrangement effectively allows all contacts to be available from the top side of the semiconductor chip.
