Abstract

A device for concentrating chemical substances for use during the fabrication of a semiconductor device uses a sample container for holding chemical substances. A feed tube in gas flow communication with the sample container introduces a carrier gas. A vapor outlet in gas flow communication with the sample container discharges a mixture of a vapor and the carrier gas. A sample heater, disposed above and apart from the sample container, heats the chemical substances to a first predetermined temperature. A gas source supplies the carrier gas, and a gas heater, in gas flow communication with both the gas source and the feed tube, heats the carrier gas to a second predetermined temperature. A condenser in flow communication with the vapor outlet produces a liquid from the vapor, and a collecting container collects the liquid.
