Thermocouple
First Claim
1. A thermocouple for measuring a temperature within a reaction chamber comprising:
- a sheath having a measuring tip and an opening;
a support member having a first distal end and an opposing a second distal end;
a first wire received within said support member;
a second wire received within said support member, said second wire being spaced-apart from said first wire within said support member; and
a spacing member attached to the sheath, the spacing member comprising a base comprising;
a first portion; and
a second portion opposite the first portion;
wherein the first portion includes a first aperture configured to receive the support member and allow the support member to independently thermally expand and contract relative to the first wire and he second wire; and
wherein the second portion includes a second aperture configured to receive the first wire and the second wire, the second aperture configured to allow the first wire, the second wire, and the support member to independently thermally expand and contract relative to each other.

Abstract
A thermocouple for use in a semiconductor processing reaction is described. The thermocouple includes a sheath having a measuring tip and an opening at the opposing end. A support member that receives a portion of a first wire and a second wire is received within the sheath. The first and second wires form a junction that contacts the inner surface of the sheath at the measuring tip. A spacing member is secured at the opening of the sheath and receives the support member. The spacing member allows the support member, first wire, and second wire to freely thermally expand relative to each other without introducing compression or tension stresses therein.
