A susceptor assembly for a reactor system may comprise a susceptor body defined by a susceptor outer edge, the susceptor body comprising a susceptor outer portion and a susceptor inner portion, wherein the susceptor outer portion is proximate the susceptor outer edge, and the susceptor inner portion is at least partially enclosed within the susceptor outer portion; a first tuning circuit comprising an edge electrode and a first resonance circuit coupled to the edge electrode, wherein the edge electrode is coupled to the susceptor body; a second tuning circuit comprising a center electrode and a second resonance circuit coupled to the center electrode, wherein the center electrode is coupled to the susceptor body; wherein the edge electrode is disposed more proximate the susceptor outer edge than the center electrode.

Reactor system comprising a tuning circuit

A wafer-supporting device for supporting a wafer thereon adapted to be installed in a semiconductor-processing apparatus includes: a base surface; and protrusions protruding from the base surface and having rounded tips for supporting a wafer thereon. The rounded tips are such that a reverse side of a wafer is supported entirely by the rounded tips by point contact. The protrusions are disposed substantially uniformly on an area of the base surface over which a wafer is placed, wherein the number (N) and the height (H [&#x3bc;m]) of the protrusions as determined in use satisfy the following inequities per area for a 300-mm wafer:(&#x2212;0.5+40)&#x2264;&#x2264;53;5&#x2264;&#x2264;100.

Examples of a plasma film forming method include repeating feeding material gas onto a substrate placed on a susceptor via a shower head provided to oppose the susceptor, performing plasma film formation on the substrate by applying high frequency power to the shower head while providing reactant gas onto the substrate, and performing post-purge of discharging the gas used in the plasma film formation while heating the shower head, for a time longer than 0.1 seconds, a plurality of times in this order.

Plasma film forming method

A method for forming a dielectric film on a substrate by plasma-assisted deposition, includes: introducing a Si-containing process gas to a reaction space wherein a substrate having a surface with patterned recesses is placed; and applying RF power to the process gas in the reaction space to form a dielectric film on the surface by plasma reaction. The RF power is comprised of pulses of high-frequency RF power and pulses of low-frequency RF power, which overlap and are synchronized.

Method for forming film by plasma-assisted deposition using two-frequency combined pulsed RF power

A method for forming a layer constituted by repeated stacked layers includes: forming a first layer and a second layer on a substrate under different deposition conditions to form a stacked layer, wherein the film stresses of the first and second layers are tensile or compressive and opposite to each other, and the wet etch rates of the first and second layers are at least 50 times different from each other; and repeating the above step to form a layer constituted by repeated stacked layers, wherein the deposition conditions for forming at least one stacked layer are different from those for forming another stacked layer.
