Sputter Coater and Thermal Evaporator – DST3-T

Desk Sputter Coater - DST3-T Three Shot Framed | VacCoat Product | Triple Target Turbomolecular Pumped Sputter Coater

The DST3-T is a triple-target turbomolecular-pumped multi vacuum-coating 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. The triple magnetron target desk sputter coater can easily switch between evaporation and sputtering condition (Not simultaneously).

The DST3-T 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 and noble) targets.

The DST3-T sputter coating system with RF power supply 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.

Plasma Cleaner

The triple target sputter coater – DST3-T can be equipped to plasma cleaner as an option. Vacuum Plasma treatment/Cleaning is the process of removing organic matter from the surface of substrate or functionalizing it through the use of an ionized gas called plasma. Plasma treatment can modify the wettability of the substrate surface and enhance its hydrophilicity or hydrophobicity for effective subsequent depositions. Also, applying plasma to the substrate prior to thin film deposition eliminates surface contaminations (C-based, Oxides) and improves the adhesion between the substrate and the subsequent layers.

Clean Vacuum of Sputter Coater

The vacuum chamber of Sputter Coater – DST3-T is Cylindrical Pyrex with 300 mm OD and 200 mm H. The DST3-T is fitted with an internally mounted 90 l/s turbomolecular pump, backed by a 6 m3/h diaphragm or 4 m3/h two-stage Rotary Vane Pump.
