Method for forming interconnections in an integrated circuit

摘要

The invention provides a method for producing wiring and contacts in an integrated circuit including the steps of forming insulated gate components on a semiconductor substrate; applying a photo-reducible dielectric layer to cover the substrate; etching holes and forming contacts; photo-reducing the dielectric to increase its conductivity; covering the resulting structure with an interconnect layer; etching the interconnect layer to define wiring in electrical contact with the contacts; and oxidizing the dielectric to reduce its conductivity.
