    摘要: An apparatus for determining temperatures of substrates in microwave and/or vacuum environments. A substrate holder with a plurality of support pins includes a temperature sensor assembly with at least a portion of a surface with a phosphorous coating is configured to be inserted in at least one pin support position from an inner area of the substrate holder and in at least one pin support position from an outer area of the substrate holder. The temperature sensor assembly includes a temperature sensor pin with a spring that is microwave transparent. The temperature sensor pin is made of a material with a thermal conductivity greater than approximately 200 W/mK and a low thermal mass which is microwave transparent. An optical transmission assembly is embedded into at least a portion of the substrate holder to receive light emissions from a surface of the temperature sensor pin.

    摘要: Apparatus for transmitting microwaves into a process chamber using a microwave pressure window assembly. The microwave pressure window assembly may include a first plate with a first aperture surrounded by a first recess for a first pressure seal, a second plate with a second aperture surrounded by a second recess for a second pressure seal, a dielectric plate configured to transmit microwaves and interposed between the first plate and the second plate and between the first pressure seal and the second pressure seal. The apertures include a first vertical step area on a first vertical side of the apertures and a second vertical step area on a second vertical side of the apertures opposite of the first vertical side. The first vertical step areas and the second vertical step areas may have a thickness of approximately 50% of a thickness of the plates that includes a dielectric plate recess.
