Claim:
1. A semiconductor chip, comprising: a semiconductor substrate having a front surface, a circuit unit formed within the semiconductor substrate and extending from the front surface into the semiconductor substrate, and a rear surface opposite the front surface, wherein the semiconductor substrate is divided into a main region and a peripheral region surrounding the main region, wherein the circuit unit is disposed in the main region, wherein the circuit unit comprise a semiconductor memory device and a semiconductor logic device; and a girder beam formed within a portion of the semiconductor substrate outside of the circuit unit, wherein the girder beam comprises: longitudinal girders formed within the semiconductor substrate and extending in a longitudinal direction of the peripheral region; and lateral girders formed within the semiconductor substrate and connecting side walls of the longitudinal girders, wherein the longitudinal girder beam comprises: first longitudinal girders disposed in the peripheral region and extending in a longitudinal direction of the peripheral region; and second longitudinal girders disposed in the main region and extending in a direction parallel to the first longitudinal girders, and wherein the lateral girder beam comprises: first lateral girders disposed in the peripheral region and connecting side walls of the first longitudinal girders; and second lateral girders disposed in the main region and connecting side walls of the second longitudinal girders.
