摘要： Methods of processing films on substrates are provided. In one aspect, the methods comprise treating a patterned low dielectric constant film after a photoresist is removed from the film by depositing a thin layer comprising silicon, carbon, and optionally oxygen and/or nitrogen on the film. The thin layer provides a carbon-rich, hydrophobic surface for the patterned low dielectric constant film. The thin layer also protects the low dielectric constant film from subsequent wet cleaning processes and penetration by precursors for layers that are subsequently deposited on the low dielectric constant film.

摘要： A method of forming source and drain regions in a semiconductor transistor. The method includes the steps of forming a first sidewall spacer on sidewall surfaces of a gate electrode that is formed on an underlying substrate, where the first sidewall spacer includes amorphous carbon. The method may also include implanting the source and drain regions in the semiconductor substrate, and removing the first sidewall spacer before annealing the source and drain regions. The method may still further include forming a second sidewall spacer on the sidewall surfaces of the gate electrode, where the second sidewall spacer has a k-value less than 4. Also, a method to enhance conformality of a sidewall spacer layer. The method may include the steps of pulsing a radio-frequency power source to generate periodically a plasma, and depositing the plasma on sidewall surfaces of a gate electrode to form the sidewall spacer layer.

摘要： Methods of depositing amorphous carbon films on substrates are provided herein. The methods reduce or prevent plasma-induced charge damage to the substrates from the deposition of the amorphous carbon films. In one aspect, an initiation layer of amorphous carbon is deposited at a low RF power level and/or at a low hydrocarbon compound/inert gas flow rate ratio before a bulk layer of amorphous carbon is deposited. After the deposition of the initiation layer, the RF power, hydrocarbon flow rate, and inert gas flow rate may be ramped to final values for the deposition of the bulk layer, wherein the RF power ramp rate is typically greater than the ramp rates of the hydrocarbon compound and of the inert gas. In another aspect, a method of minimizing plasma-induced charge damage includes depositing a seasoning layer on one or more interior surfaces of a chamber before the deposition of the amorphous carbon film on a substrate therein or coating the interior surfaces with an oxide or dielectric layer during manufacturing.
