The Solaris 150 (Surface Science Integration, Inc.) is a manual loading RTP system for R&D and pre-production. The Solaris 150 can process up to 152.4mm (6") substrates at a temperature range from RT - 1300 0C. The unique temperature measurement system of the Solaris requires virtually no calibration for different wafer types and backside emissivity differences.  The Solaris uses a unique PID process controller that ensures accurate temperature stability and uniformity.


The ATC 2200 (AJA International, Inc.) is a versatile load-locked sputter coating system.  There are 4 available sputter guns which can be configured for either DC or RF magnetron sputtering.  Samples may also be heated to 800 0C and rotated for increased uniformity.  Current sputter targets are Si (undoped), SiO2, and Si3N4.  Available gases are Ar, O2, and N2.
