Abstract: A semiconductor structure includes a source/drain region; a frontside source/drain contact disposed on the source/drain region, a via-to-backside power rail disposed on the frontside source/drain contact and on a portion of the source/drain region, and a backside power rail connected to the via-to-backside power rail.

Abstract: Implant compositions are disclosed consisting of a biocompatible carrier medium such as a saline or dextran solution and particles of collagenous material dispersed therein. The collagenous material is derived from tissue which has been milled to provide fragments of collagen fibres which preserve the architecture of the original fibres and their molecular structure. The collagenous material is also substantially free of non-fibrous tissue proteins, glycoproteins, cellular elements and lipids or lipid residues, and is non-cytotoxic. By suitable choice of particle size and concentration, the composition may be presented in injectable form or as a paste. The compositions are suitable for application in cosmetic and reconstruction surgery.

Abstract: A collagenous tissue preparation suitable for homotransplantation or heterotransplantion. The preparation is a non-resorbable, non-antigenic collagenous material which retains the natural structure and original architecture of the natural tissue. The material is substantially free of non-fibrous tissue proteins, glycoproteins, cellular elements and lipids. The tissue preparation is recolonized by host cells and revascularized after implantation into the host.

Abstract: A fibrous tissue preparation suitable for homo or heterotransplantation is obtained by treating mammalian fibrous tissue with a proteolytic enzyme followed, if desired, by further treatment with a carbohydrate splitting enzyme.
