Abstract
In an aspect, an apparatus is provided that sets and reprograms the state of programmable devices. In an aspect, the quantity of programmable material is minimized, and the programmable material that is reprogrammed from an amorphous to a crystalline state, and vice versa, is localized on a contact. In an aspect, a method is provided such that an opening is formed through a dielectric exposing a contact formed on a substrate. A spacer is formed within the opening and a programmable material is formed within the opening such that the spacer reduces the programmable material on the contact. A conductor is formed on the programmable material and the contact transmits to a signal line.
Claims5
An apparatus comprising:
- an electrical contact on a substrate;
- a dielectric over the contact, the dielectric having an opening exposing the contact, a spacer within opening over the contract, said spacer exposing less of said contact than said opening;
- a programmable material formed within the opening, the programmable material formed on said contact;
- and
- a conductor electrically coupled to the programmable material.
