Abstract:
1. A semiconductor unit comprising: (a) a first chip having oppositely-directed front and rear surfaces, left and right edges spaced apart from one another in a lateral direction and bounding the front and rear surfaces; and left and right columns of contacts at the front surface extending in a column direction transverse to the lateral direction; and (b) interconnect pads overlying the front surface of the chip, the interconnect pads being connected to at least some of the contacts, the interconnect pads and the contacts or the interconnect pads alone forming an array of external connection elements such that a first set of the external connection elements including at least some contacts of the right column or interconnect pads connected to contacts of the right column is disposed to the left of a second set of the external connection elements including at least some contacts of the left column or interconnect pads connected to contacts of the left column.
