Abstract
Various semiconductor devices and methods of testing such devices are disclosed. In one aspect, a method of manufacturing is provided that includes forming a bore from a backside of a semiconductor chip through a buried insulating layer and to a semiconductor device layer of the semiconductor chip. A conductor structure is formed in the bore to establish an electrically conductive pathway between the semiconductor device layer and the conductor structure. The conductor structure may provide a diagnostic pathway.
