A method for depositing an amorphous carbon layer on a substrate includes the steps of positioning a substrate in a chamber, introducing a hydrocarbon source into the processing chamber, introducing a heavy noble gas into the processing chamber, and generating a plasma in the processing chamber. The heavy noble gas is selected from the group consisting of argon, krypton, xenon, and combinations thereof and the molar flow rate of the noble gas is greater than the molar flow rate of the hydrocarbon source. A post-deposition termination step may be included, wherein the flow of the hydrocarbon source and the noble gas is stopped and a plasma is maintained in the chamber for a period of time to remove particles therefrom.

Methods for high temperature deposition an amorphous carbon film with improved step coverage are provided. In one embodiment, a method for of depositing an amorphous carbon film includes providing a substrate in a process chamber, heating the substrate at a temperature greater than 500 degrees Celsius, supplying a gas mixture comprising a hydrocarbon compound and an inert gas into the process chamber containing the heated substrate, and depositing an amorphous carbon film on the heated substrate having a stress of between 100 mega-pascal (MPa) tensile and about 100 mega-pascal (MPa) compressive.
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.
