Turbo Pumped Desk Sputter and Carbon Coater – DSCT

Vac Coat DSCT | Turbo Pumped Sputter and Carbon Coater

Turbo pumped sputter and carbon coater – DSCT is configured as a high-vacuum sputter coater and carbon coater with interchangeable heads in one instrument suitable for scanning electron microscope (SEM) sample preparation. The system is able to sputter noble metals such as gold (Au), palladium (Pd), platinum (Pt), and gold/palladium (Au/Pd), as well as oxidizing metals like tungsten and chromium, together with thermal evaporation of different carbon sources (Fiber or rod) to coat on samples with non-conductive or poorly conductive surface for electron microscopy imaging or other applications.

This high-vacuum SEM coater offers high quality uniform films with fine grain sizes which are suitable for specimens that require high resolution and high quality characterization such as FE-SEM, EDS/WDS, TEM, and EBSD. The DSCT with a 2” magnetron cathode, 80 W switching DC power supply and high current power supply for carbon evaporation, could be used for research and different thin film applications.

DSCT can be equipped with a water-cooled cathode which makes it suitable for long time sputtering deposition. Also, DSCT can be provided with a 160 W power supply to facilitate sputtering of targets like chromium, tungsten, and other oxidizing metal targets (Optional).

The full-automatic sputter and carbon coating processes allows easy, precise, and repeatable performance. The maximum size of the substrates in this model could be 4 inches.

Carbon Evaporation of DSCT

Mini-size coating system model DSCT can carbon coat with fine grains to produce uniform thin films on different surfaces using carbon fiber or carbon rod (Optional).

Pulsed Carbon Fiber Evaporation

The DSCT coater is able to perform pulsed carbon fiber evaporation. Short pulses provide more controlled deposition and significantly reduces the amount of debris associated with traditional carbon deposition.

Carbon Rod Evaporation (Optional)

The DSCT could be equipped with carbon rod evaporator head (optional). For this case an external 0-100 A high current power supply should be used instead of the internal high current power supply which is designed for carbon fiber evaporation.

Touch Screen Control

DSCT, the desk SEM coater, is equipped with a 7” colored touch-screen panel and full automatic control using a user-friendly software to control and adjust the deposition process data. The vacuum and coating sequence information can be observed as digital data or curves on the touch screen. The last 300 coatings information is saved on the history page.

Sample Holder Stages

The DSCT can be equipped with different sample stage configurations depending on the user requirements. The standard sample stage is rotatable with adjustable height and angle and can be changed easily. The rotary planetary sample stage is a good choice for uniform coating of porous specimens (Optional).

Clean Vacuum

The vacuum chamber is Cylindrical Pyrex. The DSCT is fitted with an internally mounted 90 L/s turbo molecular pump, backed by a 6 m3/h two-stage rotary vane pump. It introduces clean vacuum without oil contamination which normally exists with ordinary diffusion pump.
