The DST3-T, Triple Target Turbo Pumped Sputter Coater, is a multi vacuum coater system that combines thermal evaporator and sputter coater in one single compact desktop system. The high vacuum system is suitable for deposition of a wide range of materials. Triple magnetron target desk sputter coater can easily switch between Evaporation and Sputtering condition (Not Simultaneously).
The DST3-T, Magnetron Desk Sputter Coater, 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 sputter coater system is equipped with an auto adjustable matching box, minimizing the reflected power in the RF sputtering process. 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-T is available in two models:
- DST3 – TA (Angled Cathodes):
The DST3-TA is equipped with three angled cathodes with a common focal point. The sputter coater system 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 inches.
- DST3 –TS (Straight Cathodes):
DST3-TS with three straight 2 inches water-cooled cathodes is suitable for sputtering a single large specimen with diameter up to 20 cm or several small specimens.

Thermal Evaporation of Triple Target Turbo Pumped Sputter Coater
The DST3-T is equipped with a high current power supply and low-voltage (resistive) thermal evaporation platform suitable for a wide variety of thermal evaporation applications. The sputter coating system allows controlled thermal evaporation of wide range materials onto substrate. Different types of thermal evaporation sources (Boat, Basket, and Coil) can be installed on the single thermal source holder.
Touch Screen Control
Triple Target Turbomolecular Pumped Sputter Coater 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.
Sputter Coater Sample Holder
The holder is made according to the conventional size of microscope slides, but the user can order customize size according to his/her needs. On the sample holder number of clamps are created to hold the small samples with a simple method during the rotation.
The triple target sputter coater – DST3-T is equipped to plasma cleaner option. Vacuum Plasma Cleaning is the process of removing organic matter from the surface of substrate through the use of an ionized gas called plasma. Pre-Cleaning the substrate prior to the deposition of film to eliminate contamination (C-based, Oxides) from substrate surface improve the adhesion between the substrate and the subsequent layers.
