Method and apparatus of concentrating chemicals for semiconductor device manufacturing

Abstract

A method of concentrating chemicals for semiconductor devices, which includes the steps of heating a sample container by using a high-energy light source, vaporizing the chemicals by injecting a high-temperature gas into the sample container through an injection opening in the sample container and discharging the vaporized chemicals by the pressure of the gas through a gas outlet formed on the sample container. An apparatus of concentrating chemicals for semiconductor devices includes a sample container having a sample-supply window, a gas-injection opening and a gas outlet. A high-energy light source heats the sample container and a gas-supply source supplies the gas through a gas-injection opening in the sample container. A gas-heating device located between the sample container and the gas-supply source heats the gas provided by the gas-supply source.
