A method of removing material from a substrate, and a plasma discharge device wherein a plasma is excited by microwave energy having an electric field which is azimuthally and axially uniform in relation to the plasma tube. The microwave cavity is divided longitudinally into sections by conducting partitions, each of which is separately fed with microwave energy, and the plasma tube extends through openings in the partitions.

Microwave plasma discharge device

A combination contact temperature probe/wafer support includes a thermocouple enclosing probe head of low thermal mass and large contact area supported by a support means such that 1) there is a high thermal resistivity connection between the support means and the probe head, and 2) the probe head is self orienting under the weight of the wafer so that the contact area is maintained coplanar with the surface of the wafer.

Contact temperature probe with unrestrained orientation

An electrodeless lamp is started by coupling microwave power of a first frequency to a lamp cavity, while the discharge is maintained by coupling microwave power of a second frequency, wherein the first frequency is lower than the second frequency. A cooling fluid is impinged on the lamp bulb immediately before the application of the microwave power of the first frequency.
