Abstract:
A method of forming a conductive layer on a semiconductor device, the method comprising:(i) positioning a semiconductor device within a chemical vapor deposition chamber; (ii) introducing a conductive precursor gas into the chemical vapor deposition chamber for a first period of time; (ii) introducing a reactant into the chemical vapor deposition chamber for a second period of time, so that the conductive layer is formed on the semiconductor device and organic waste compounds positioned within and on the conductive layer of the first thickness are removed; (iv) monitoring the rate of deposition of the conductive layer, wherein the supply of conductive precursor gas is halted upon determining when the rate of deposition is less than a desired threshold; and (v) continuing acts (ii), (iii), and (iv) until the conductive layer of a desired thickness is achieved.
