摘要： A transformer-coupled plasma source using toroidal cores forms a plasma with a high-density of ions along the center axis of the torus. In one embodiment, cores of a plasma generator are stacked in a vertical alignment to enhance the directionality of the plasma and generation efficiency. In another embodiment, cores are arranged in a lateral array into a plasma generating plate that can be scaled to accommodate substrates of various sizes, including very large substrates. The symmetry of the plasma attained allows simultaneous processing of two substrates, one on either side of the plasma generator.

摘要： A toroidal plasma source (28) within a substrate processing chamber (10). The toroidal plasma source forms a poloidal plasma with theta symmetry. The poloidal plasma current is essentially parallel to a surface of the plasma generating structure, thus reducing sputtering erosion of the inner walls. The plasma current is similarly essentially parallel to a process surface (32) of a substrate (34) within the chamber. In a further embodiment, a shaped member (66) between the substrate and the plasma source controls the plasma density in a selected fashion to enhance plasma processing uniformity.

摘要： High tensile stress in a deposited layer such as silicon nitride, may be achieved utilizing one or more techniques, employed alone or in combination. High tensile stress may be achieved by forming a silicon-containing layer on a surface by exposing the surface to a silicon-containing precursor gas in the absence of a plasma, forming silicon nitride by exposing said silicon-containing layer to a nitrogen-containing plasma, and then repeating these steps to increase a thickness of the silicon nitride created thereby. High tensile stress may also be achieved by exposing a surface to a silicon-containing precursor gas in a first nitrogen-containing plasma, treating the material with a second nitrogen-containing plasma, and then repeating these steps to increase a thickness of the silicon nitride formed thereby. In another embodiment, tensile film stress is enhanced by deposition with porogens that are liberated upon subsequent exposure to UV radiation or plasma treatment.

摘要： A method of depositing a silica glass insulating film over a substrate. In one embodiment the method comprises exposing the substrate to a silicon-containing reactant introduced into a chamber in which the substrate is disposed such that one or more layers of the silicon-containing reactant are adsorbed onto the substrate; purging or evacuating the chamber of the silicon-containing reactant; converting the silicon-containing reactant into a silica glass insulating compound by exposing the substrate to oxygen radicals formed from a second reactant while biasing the substrate to promote a sputtering effect, wherein an average atomic mass of all atomic constituents in the second reactant is less than or equal to an average atomic mass of oxygen; and repeating the exposing, purging/evacuating and exposing sequence a plurality of times until a desired film thickness is reached.
