DSCT – Dual Purpose Sputter and Carbon Coater
The DSCT High Vacuum SEM Coater is configured as a sputter coater and fibre carbon coater with interchangeable heads in one instrument suitable for Scanning Electron Microscope (SEM) sample preparation. A wide range of materials could be deposited by DSCT such as gold (Au) platinum/palladium (Pt / Pd) alloy silver (Ag) chromium (Cr) tungsten (W) iridium (Ir) and etc.

Overview
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 oxidising metal targets (optional).
The full-automatic sputter and carbon coating processes allows easy, precise, and repeatable performance.

Pulsed Carbon Fibre Evaporation
The DSCT coater is able to perform pulsed carbon fibre 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 fibre evaporation.

Touch Screen Control
DSCT, the desk SEM coater, is equipped with a 7” coloured 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).
