摘要:
According to one embodiment of the invention, a method of modifying a mechanical, physical and/or electrical property of a dielectric layer comprises exposing the dielectric layer to a first dose of electron beam radiation at a first energy level; and thereafter, exposing the dielectric layer to a second dose of electron beam radiation at a second energy level that is different from the first energy level.
摘要:
A method for seasoning a chamber and depositing a low dielectric constant layer on a substrate in the chamber is provided. In one aspect, the method includes seasoning the chamber with a first mixture comprising one or more organosilicon compounds and one or more oxidizing gases and depositing a low dielectric constant layer on a substrate in the chamber from a second mixture comprising one or more organosilicon compounds and one or more oxidizing gases, wherein a ratio of the total flow rate of the organosilicon compounds to the total flow rate of the oxidizing gases in the first mixture is lower than the total flow rate of the organosilicon compounds to the total flow rate of the oxidizing gases in the second mixture.
摘要:
A method for depositing a silicon oxycarbide hard mask on a low k dielectric layer is provided. Substrates containing a silicon oxycarbide hard mask on a low k dielectric layer are also disclosed. The silicon oxycarbide hard mask may be formed by a processing gas comprising a siloxane.
