摘要:
A silicon oxide layer is deposited on a substrate by chemical vapor deposition (CVD) by reacting an organoaminosilane precursor, selected from specified categories, with an oxidizing agent under conditions for the formation of a silicon oxide film. Diisopropylaminosilane is the preferred organoaminosilane precursor for the formation of the silicon oxide film.

A method of forming a fluorinated silicon oxide dielectric layer (33) by plasma chemical vapor deposition. The method includes the steps of creating a plasma in a plasma chamber (10) and introducing a silicon-containing gas, a fluorine-containing gas, oxygen and an inert gas such that the gases are excited by the plasma and react proximate a substrate (16) to form a fluorinated silicon oxide layer on the surface of the substrate (16). The fluorinated layer so formed has a dielectric constant which is less than that of a silicon oxide layer.

摘要:
A process of preparing a moisture-resistant fluorine containing SiOx film includes steps of supplying reactant gases containing silicon, oxygen and fluorine into a process chamber and generating plasma in the process chamber, supporting a substrate on a substrate support in the process chamber and growing a fluorine-containing SiOx film on the substrate by contacting the substrate with the plasma while maintaining temperature of the film above 300 °C. The silicon and fluorine reactants can be supplied by separate gases such as SiH4 and SiF4 or as a single SiF4 gas and the oxygen reactant can be supplied by a pure oxygen gas. The SiH4 and SiF4 can be supplied in a ratio of SiH4(SiH4+SiF4) of no greater than 0.5. The process can provide a film with a fluorine content of 2-12 atomic percent and argon can be included in the plasma to assist in gap filling. The plasma can be a high density plasma produced in an ECR, TCP or ICP reactor and the substrate can be a silicon wafer including one or more metal layers over which the fluorine-containing SiOx film is deposited. The substrate support can include a gas passage which supplies a temperature control gas into a space between opposed surfaces of the substrate and the substrate support for maintaining the substrate at a desired temperature.
摘要:
A method and apparatus are disclosed for depositing a dielectric film in a gap having an aspect ratio at least as large as 6:1. By cycling the gas chemistry of a high-density-plasma chemical-vapor-deposition system between deposition and etching conditions, the gap may be substantially 100% filled. Such filling is achieved by adjusting the flow rates of the precursor gases such that the deposition to sputtering ratio during the deposition phases is within certain predetermined limits.
