Abstract
Official abstract text for this publication.
A photovoltaic cell is provided as a composite unit together with elements of an integrated circuit on a common substrate. In a described embodiment, connections are established between a photovoltaic cell portion and a circuitry portion of an integrated structure to enable self-powering of the circuitry portion by the photovoltaic cell portion.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of forming an integrated circuit with a photovoltaic cell, comprising: forming PMOS and NMOS transistors in a front side of a semiconductor wafer; forming first and second contacts to the PMOS and NMOS transistors; forming first and second through-silicon vias (TSVs) into the semiconductor wafer; bonding the semiconductor wafer to a carrier wafer on the front side of the semiconductor wafer; thinning the semiconductor wafer from a backside t…
