The DektakXT is the 10th generation, and latest, profiler from the Dektak Range. It is fast, and has an automated XY Theta sample stage. Vertical reproducibility is 5 Angstrom, and it can measure steps from nm to 1mm deep. It can handle samples that are up to 35mm thick, and up to 300mm in dia
Dicing saw capable of sawing flat substrates up to 150mm diameter.
We can saw Glass, Quartz, Silicon and other materials by suitable choice of blades.
Silicon dicing cuts
Typical: width 70 µm, depth 1000 µm
High precison: width 26 µm, depth 325 µm
This is a Plasma etcher in a barrel configuration. It is used primariliy for removing organic materials in an Oxygen plasma, such as photoresist. It is an effective technique for cleaning up the residues of photoresist that remain after the Photolithography and develop processes before samples
The Edwards Belljar evaporator is a turbo and scroll pumped system capable of evaporating up to 4 different materials in the same vacuum cycle.
This equipment has four independent source positions allowing multiple layers to be deposited without breaking vacuum. The maximum sample size is 200mm diameter, or multiple smaller pieces.
This equipment has diffusion High vacuum pump and oil rotary backing pump. It has a rotary source holder allowing up to 4 different materials to be deposited in sequence in the same vacuum cycle, and has a thickness monitor. Operation is entrely manual.
