Abstract:
A method of descumming a dielectric layer is provided. In an embodiment the dielectric layer is deposited over a substrate, and a photoresist is applied, exposed, and developed after the photoresist has been applied. Once the pattern of the photoresist is transferred to the underlying dielectric layer, a descumming process is performed, wherein the descumming process utilizes a mixture of a carbon-containing precursor, a descumming precursor, and a carrier gas. The mixture is ignited into a treatment plasma, and the treatment plasma is applied to the dielectric layer in order to descum the dielectric layer.

Claim (Index 12):
A method of manufacturing a semiconductor device, the method comprising:\n patterning a dielectric layer to form a first surface of the dielectric layer; and after patterning the dielectric layer, descumming the first surface of the dielectric layer, wherein descumming the first surface of the dielectric layer comprises:\n breaking first bonds between silicon atoms and nitrogen atoms at the first surface of the dielectric layer, wherein breaking the first bonds creates first open terminal groups at the first surface of the dielectric layer; and \n bonding carbon atoms to the first open terminal groups.
