    Abstract: An apparatus for measuring a temperature of an assembly that is internal to a process chamber. The apparatus may include a light pipe positioned between a lamp radiation filtering window and the assembly, the light pipe has a first end with a bevel configured to redirect infrared radiation emitted from the assembly through the light pipe and has a second end distal to the first end, an optical assembly configured to collimate, filter, and focus infrared radiation from the second end of the light pipe, an optical detector configured to receive an output from the optical assembly and generate at least one signal representative of the infrared radiation, a temperature circuit that transforms the at least one signal into a temperature value, and a controller that is configured to receive the temperature value and to make adjustments to other process parameters of process chamber based on the temperature value.

    Abstract: The embodiments described herein generally relate to a flexible standoff for use with a lamphead assembly in a thermal processing chamber. In one embodiment, the lamphead assembly can include a lamphead with one or more fixed lamphead positions, a lamp bulb, a lamp base with a standoff contact adaptor and a flexible standoff capable of attaching and positioning the lamp assembly. The flexible standoff can include a socket configured to receive a lamp base of a lamp assembly, a housing configured to position a lamp bulb of a lamp assembly in thermal connection with a processing chamber, a contact adaptor configured to electrically connect to a power supply and a conductive material to electrically connect the socket and the contact adaptor.

    Abstract: Embodiments disclosed herein include a method of modeling a rapid thermal processing (RTP) tool. In an embodiment, the method comprises developing a lamp model of an RTP tool, wherein the lamp model comprises a plurality of lamp zones, calculating an irradiance graph for the plurality of lamp zones, multiplying irradiance values of the plurality of lamp zones in the irradiance graph by a power of an existing RTP tool at a given time during a process recipe, summing the multiplied irradiance values for the plurality of lamp zones to form an irradiation graph of the lamp model, using the irradiation graph as an input to a machine learning algorithm, and outputting the temperature across a hypothetical substrate from the machine learning algorithm.
