Abstract:
1. A treatment system for removing material on a substrate, comprising: a temperature controlled process chamber configured to contain a substrate and configured to facilitate a non-plasma environment, said substrate having a surface oriented to be treated by said non-plasma environment; a temperature controlled substrate holder mounted within said temperature controlled process chamber, and configured to support said substrate, orient said substrate such that said surface is exposed to said non-plasma environment, and control a temperature of said substrate when said substrate is resting on an upper surface of said temperature controlled substrate holder; a vacuum pumping system coupled to said temperature controlled process chamber; a chemical treatment system coupled to said temperature controlled process chamber and configured to introduce a process gas to said temperature controlled process chamber, wherein said process gas chemically alters at least a portion of said surface on said substrate exposed to said non-plasma environment, wherein said process gas comprises as incipient ingredients HF and optionally ammonia (NH a thermal treatment system, separate from said temperature-controlled substrate holder, coupled to said temperature controlled process chamber and configured to elevate the temperature of said substrate in said temperature controlled process chamber, wherein said elevated temperature causes evaporation of said chemically altered surface layers, and wherein said thermal treatment system comprises one or more radiative heat lamps arranged to directly irradiate said surface of said substrate that is exposed to said non-plasma environment; and a controller coupled to said temperature controlled substrate holder, said chemical treatment system, and said thermal treatment system and configured to control the amount of said process gas introduced to said substrate, and the temperature to which said substrate is set.
