Patent ID: 7859081

Claim:
A capacitor comprising: a substrate; a first electrically insulating layer over the substrate; a fin comprising a semiconducting material over the first electrically insulating layer; a first electrically conducting layer over the first electrically insulating layer and adjacent to the fin such that there exists no intervening layer between the first electrically conducting layer and the fin; a second electrically insulating layer adjacent to the first electrically conducting layer; and a second electrically conducting layer adjacent to the second electrically insulating layer, wherein: the first electrically insulating layer comprises an oxide layer having a first surface; the fin is a silicon fin having a first portion extending into the first electrically insulating layer and having a second portion protruding from the first surface; the second electrically insulating layer comprises a high-k dielectric material; the first electrically conducting layer comprises a first section at a first side of the silicon fin and a second section at an opposing second side of the silicon fin; a distance between an outside edge of the first section and an outside edge of the second section is a first distance; the second portion of the silicon fin has a second surface; a distance between the first surface and the second surface is a second distance; and the second distance is between approximately six times the first distance and approximately twelve times the first distance.
