A substrate processing apparatus includes: a rotary table provided in a processing container; a rotation mechanism configured to rotate the rotary table; recesses provided on an upper surface of the rotary table along a rotation direction of the rotary table and configured to accommodate substrates, respectively; a processing gas supply provided above the rotary table and configured to supply a processing gas onto the rotary table to process each of the substrates; a heater configured to heat the rotary table; a support configured to support the substrates in upper regions above the recesses so that the heater heats the substrates before being accommodated in the recesses; and an elevating mechanism configured to raise and lower the support relative to the rotary table so that the substrates are collectively moved from the upper regions into the recesses.

A method for depositing a silicon nitride film is provided. A silicon nitride film is deposited in a depression formed in a surface of a substrate from a bottom surface and a lateral surface by ALD toward a center of the depression in a lateral direction so as to narrow a space at the center of the depression. First nitrogen radicals are adsorbed into the depression immediately before a stage of filling the space at the center with the silicon nitride film deposited toward the center of the depression. A silicon-containing gas is adsorbed on the first nitrogen radical in the depression by physical adsorption. Second nitrogen radicals are supplied into the depression so as to release the silicon-containing gas from the first nitrogen radical and to cause the released silicon-containing gas to react with the second nitrogen radical, thereby depositing a silicon nitride film to fill the central space.

The present disclosure provides systems and methods for processing channel structures of substrates that include positioning the substrate in a first processing chamber having a first processing volume being in fluid communication with a plasma source. The substrate can include a channel structure with high aspect ratio features having aspect ratios greater than about 20:1.
