Title: Feed gas vaporizer for arc chamber
Inventor: POVALL SIMON
IPC: H01L21/265
Filed: 2001-04-04
Abstract: PROBLEM TO BE SOLVED: To provide a vaporizer to generate feed gas for an arc chamber. SOLUTION: This vaporizer to generate feed gas for the arc chamber as an ion source has a crucible which is heated to the temperature to sublimate a material in the crucible. This sublimation generates vapor for using as the feed gas. The vaporizer also has a heating element to heat the crucible and a cooling element which has a form extending along the crucible to let cooling fluid flow through it. When a switch of the heating element is being turned off, forced cooling of the crucible makes it possible to quickly cool the crucible so that it becomes possible to stop the supply of the feed gas instantly. This quick stopping is important when the feed gas for the arc chamber as the ion source is changed. By forced cooling of the crucible and at the same time by energizing the heating element, exact control of the crucible is possible at a low operating temperature when it is required.
