Abstract
The invention is directed to an improved microelectronics device that reduces BEOL delamination by reducing the tensile stress imposed on the via which connects first level interconnects with the BEOL. Tensile stress imposed on the via is reduced by shifting the via towards the center of a silicon chip or alternatively shifting the UBM towards the corners of the silicon chip.
