Triple Target Desk Sputter Coater

The DST3 is equipped with a large chamber (300 mm diameter) and three 2” diameter water cooled cathodes which make it suitable for long time deposition. The magnetron desk sputter coater is equipped with RF and DC power supplies. It can sputter semiconductors, dielectrics and metal (oxidizing & noble) targets.The system is equipped with an auto adjustable matching box, minimizing the reflected power in the RF sputtering.

For increasing film adhesion to the substrate and to improve the film structures, a 300 V, DC bias voltage can be applied to the substrate (optional).

According to state of the cathodes, DST3 is available in two models:

 

  • DST3 – A (Angled Cathodes):

 

The DST3-A is equipped with three angled cathodes with a common focal point. It can sputter from two or three (optional) targets simultaneously or independently to form alloys or multilayer deposition respectively.

The maximum size of substrates in this model could be 3”.

  • DST3 – S (Straight Cathodes):

DST3-S with three straight cathodes is suitable for sputtering a single large specimen with diameter up to 20 Cm or several small specimens.

Clean Vacuum

The vacuum chamber is Cylindrical Pyrex with 300 mm OD and 200 mm H. The DST3 is fitted with an internally mounted 90L/s turbo molecular pump, backed by a 1.4 m3/h diaphragm or 4 m3/h two stage rotary vain pump.

 

Touch Screen Control

DST3, is equipped with a 7” colored touch screen and semi-automatic control and data input that can be operated by even inexperienced users. The vacuum and deposition information can be observed as digital data or curves on the touch screen. Information of the last 300 coating can also be saved in the history page.
