Patent ID: 7019328

Claim:
A first transistor comprising: a source contact formed on a base layer; a drain contact formed on the base layer, the source contact and the drain contact defining a channel region therebetween; at least one of a first modifier coating on the source contact, a second modifier coating on the drain contact, and a third modifier coating covering the base layer in the channel region; and a semiconductor region extending over the channel region and making electrical contact with the source contact and the drain contact, wherein the semiconductor region contacts a receiving surface formed by one of the first modifier coating and the source contact, one of the second modifier coating and the drain contact, and one of the third modifier coating and the base layer, and wherein at least one of the first modifier coating, the second modifier coating, and the third modifier coating are selected such that a surface energy of a first portion of the receiving surface in the channel region is greater than or substantially equal to surface energies of a second portion and a third portion of the receiving surface over the source contact and the drain contact, respectively.
