    摘要: A semiconductor substrate with a groove is placed in a plasma generating reaction chamber. Silicon, oxygen and hydrogen containing gases are introduced into the reaction chamber as process gases. A ratio of a gas flow of the hydrogen containing gas except the silicon containing gas to a total gas flow of the silicon containing gas and the oxygen containing gas defines a first gas-flow ratio. A ratio of a gas flow of the oxygen containing gas to that of the silicon containing gas defines a second gas-flow ratio. The first and second gas-flow ratios establish a linear function for a critical condition. A cluster formation condition is set up by relatively increasing the first gas-flow ratio while relatively decreasing the second gas-flow ratio with respect to the critical condition. A cluster suppression condition is also set up by relatively decreasing the first gas-flow ratio while relatively increasing the second gas-flow ratio with respect to the critical condition. The process gases are supplied to the reaction chamber under the cluster formation condition and under the cluster suppression condition, alternately, to form an insulating film buried in the groove.

    摘要: Disclosed is a method of forming a silicon oxide layer comprising: supplying at least a gas containing Si as a raw gas to a semiconductor substrate having a recess formed on its surface to form a primary reactant on the surface, then performing dehydration condensation to form a silicon oxide layer above the semiconductor substrate; removing a part of the silicon oxide layer until a portion of the silicon oxide layer formed in the recess that has a lower density than the silicon oxide layer formed in a vicinity of the surface is at least partially exposed; and supplying a gas containing Si to the silicon oxide layer having a lower density.
