Abstract: Methods and apparatus disclosed herein generally relate to lamp heating of process chambers used to process semiconductor substrates. More specifically, implementations disclosed herein relate to arrangement and control of lamps for heating of semiconductor substrates. In some implementations of the present disclosure, fine-tuning of temperature control is achieved by dividing different lamps within an array of lamps into various subgroups or lamp assemblies defined by a specific characteristic. These various subgroups may be based on characteristics such as lamp design and/or lamp positioning within the processing chamber.

Abstract: Embodiments herein relate to chamber liners with a multi-piece design for use in processing chambers. The multi-piece design can have an inner portion and an outer portion. A portion of the inner surface of the outer portion may be designed to be in contact with the outer surface of the inner portion at a single junction point, creating a thermal barrier between the inner portion and outer portion, thus reducing heat transfer from the inner portion and outer portion. The thermal barrier creates higher temperatures at the chamber liner inner surface and therefore leads to shorter heat up times within the chamber. Additionally, the thermal barrier also creates lower temperatures near the base ring and outer surface of the outer ring, thereby protecting the chamber walls and requiring less thermal regulation/dissipation at the chamber walls.

Abstract: Embodiments of the invention generally relate to susceptor support shafts and process chambers containing the same. A susceptor support shaft supports a susceptor thereon, which in turn, supports a substrate during processing. The susceptor support shaft reduces variations in temperature measurement of the susceptor and/or substrate by providing a consistent path for a pyrometer focal beam directed towards the susceptor and/or substrate, even when the susceptor support shaft is rotated. The susceptor support shafts also have a relatively low thermal mass which increases the ramp up and ramp down rates of a process chamber. In some embodiments, a custom made refractive element can be removably placed on the top of the solid disc to redistribute secondary heat distributions across the susceptor and/or substrate for optimum thickness uniformity of epitaxy process.
