摘要: A method of forming a feature in a low-k dielectric layer is provided. A low-k dielectric layer is placed over a substrate. A patterned photoresist mask is placed over the low-k dielectric layer. At least one feature is etched into the low-k dielectric layer. A CO conditioning is preformed on the at least one feature after the at least one feature is etched. The patterned photoresist mask is stripped after the CO conditioning.

摘要: A method of dechucking a wafer, with a low-k dielectric layer, held onto an electrostatic chuck by an electrostatic charge in a plasma chamber is provided. The electrostatic clamping voltage is removed. An essentially argon free dechucking gas is provided into the plasma chamber. A dechucking plasma is formed from the dechucking gas in the plasma chamber. The dechucking plasma is stopped.
