Abstract
An integrated circuit (IC) chip is provided. In one aspect, a semiconductor substrate includes active devices at its front surface and power delivery tracks on its back surface. The active devices are powered through mutually parallel buried power rails, with the power delivery tracks running transversely with respect to the power rails, and connected to the power rails by a plurality of Through Semiconductor Via connections, which run from the power rails to the back of the substrate. The TSVs are elongate slit-shaped TSVs aligned to the power rails and arranged in a staggered pattern, so that any one of the power delivery tracks is connected to a first row of mutually parallel TSVs, and any power delivery track directly adjacent to the power delivery track is connected to another row of TSVs which are staggered relative to the TSVs of the first row. A method of producing an IC chip includes producing the slit-shaped TSVs before the buried power rails.
