Haftmaterial für programmierbare Vorrichtung

In an aspect, an apparatus is provided that sets and reprograms the state of programmable devices. In an aspect, a method is provided such that an adhesive (215), like Ti or polysilicon, is formed on a dielectric (210) and on an electrode (230A), the adhesive patterned exposing the electrode, and a programmable material (404) is formed on the adhesive and on the electrode. In another aspect, a method is provided such that an adhesive (214) is formed on a dielectric (210), an opening (220) is formed through the dielectric exposing a contact (170) formed on a substrate, and a programmable material (404), preferably a chalcogenide, is formed on the adhesive and on a portion of the contact. A conductor (410) is formed on the programmable material and the contact transmits to a signal line.
