About
Our Strip annealer is primarily used for ohmic contact formation on III-V compound semiconductors. The system runs in a forming gas environment to keep oxygen contamination minimized. Temperature of the graphite strip is electronically controlled to prevent overshoot and the phase changes of the metal can be observed through the stereo microscope while annealing is taking place. This observation is often the best way to get the best ohmic contact. Thermal interlocks prevent the system from overheating and maximum anneal times are on the order of several minutes. Anneals up to 500°C are permitted. The graphite strip is only 1.5 inches wide, limiting the sample size.
