Claim Text:
1. A method of making a substrate-through electrical connection having an on-off function, comprising: providing a semiconductor substrate ( etching a trench ( after etching the trench, doping ( providing an insulating/dielectric layer ( filling the trench with a conductive or semi-conductive material ( removing the deposited material ( thinning the substrate ( providing both sides of the substrate with an insulation ( doping the substrate-through electrical connection on a respective side of the substrate with an opposite doping type to that of the substrate to provide a source region ( providing contacts ( providing contact(s) ( the contacts to the substrate-through electrical connection form source and drain contacts, respectively, of a transistor, and the contact(s) to the trench material form(s) gate contacts of a transistor.
