    摘要: In a semiconductor device, through hole vias or through silicon vias (TSV) may be formed so as to include an efficient stress relaxation mechanism, for instance provided on the basis of a stress relaxation layer, in order to reduce or compensate for stress forces caused by a pronounced change in volume of the conductive fill materials of the through hole vias. In this manner, the high risk of creating cracks and delamination events in conventional semiconductor devices may be significantly reduced.

    摘要: A method of manufacturing a semiconductor device begins by fabricating an n-type metal oxide semiconductor (NMOS) transistor structure on a semiconductor wafer. The method continues by forming an optically reflective layer overlying the NMOS transistor structure, forming a layer of tensile stress inducing material overlying the optically reflective layer, and curing the layer of tensile stress inducing material by applying ultraviolet radiation. Some of the ultraviolet radiation directly radiates the layer of tensile stress inducing material and some of the ultraviolet radiation radiates the layer of tensile stress inducing material by reflecting from the optically reflective layer.
