Sputter Coater | 10 Types of Desk Sputter Coaters

Sputter Coaters

Sputter coating as a common method for thin film deposition by vacuum plasma is used in various applications, such as fabrication of nano-electronic and optical devices, sensors, solar cells, as well as SEM sample preparation. Ion sputter coaters generate a sustainable plasma under controlled conditions to obtain a uniform coating. Magnetron desk sputter coaters produced by Vac Coat Ltd. are pioneers of automated low and high vacuum sputter coating machines for producing thin films of various materials by using DC/RF sputtering techniques.

Ion Sputter Coating Technique

Ion Sputtering is a method to deposit thin films of various materials on a substrate. Nowadays, ion sputter coating (shortened as sputtering) is used in SEM Coaters for coating Scanning Electron Microscope (SEM) samples with a conductive thin film. This is an essential step in SEM sample preparation to reduce electric charging of the sample surface, diminishing heat damage to the sample, and achieving high-quality images. Also, sputtering is widely used in thin film deposition for numerous research applications in solar cell, battery, sensors, and micro/nano-electronics.

How Does A Sputter Coater Work?

Sputter coating of a sample requires plasma formation of a process gas between two electrodes to sputter the atoms of a target material placed on the cathode, which are deposited on the substrate afterward. This process needs vacuuming and precise manipulation of the base and working pressure of the chamber, process gas flow, substrate bias voltage and temperature, cathode voltage, plasma current, and deposition time to obtain desired thickness and structure of the coated layer. These numerous parameters can be handled accurately by using an automated sputter coater machine with programmable coating processes through user-friendly software.

The rotary-pumped sputter coater DSR1 is favorable for low vacuum coating thin films of noble, non-oxidizing metals like gold (Au) and silver (Ag) and platinum (Pt), for conventional SEM imaging.

High-vacuum ultrafine deposition of oxidizing and non-oxidizing is made possible by DST1 turbo-pumped sputter coater, introduced in two chamber size, Dia. 170 and 300 mm.

Vac Coat sputter coaters can also be used as a carbon coater in a single compact desktop system with optional carbon fiber/rod evaporation attachment in low vacuum DSCR and high-vacuum DSCT coater models.

Consecutive layer coating and co-sputtering is made feasible with DST3 multi-cathode sputtering system, in two different cathode configurations, angled (DST3-A) and straight (DST3-S). These models are also offered with thermal evaporation option (DST3-TA and DST3-TS). Large samples uniform coating (up to 8 inches) is made possible with uniquely designed cathode masks in DST3-S model.

Glove box turbo-pumped multi-cathode sputter coater DST2-TG can be mounted inside a glove box, where purity is vital. This high-vacuum coating system can co-deposit materials through both sputtering and thermal evaporation methods, without breaking the vacuum.

Does your device need to be installed by VacCoat experts?

Setting up our system is very straightforward. We have also provided a clear user manual and instructional videos that help you to set up the system step by step. Remember that our after sales service are always available to help and answer your questions.

What is difference between the DSR1 and DST1?

The ultimate pressure in DST1 is very lower than DSR1 (5×10-6 Torr in DST1, compared to 5×10-2 Torr in DSR1). DST1 is able to sputter not only noble metals, but also oxidizing targets. The grain size of the deposited layers of metals like Cr and W are much finer than the deposited noble metals, thus more suitable for the field emission electron microscopes (FESEM).

What is the application of a planetary sample holder?

In the case of coating on porous samples, inside of the holes will not be coated well during the deposition and would be blind spots for an electron microscope. The planetary sample holder maximizes the coverage of the coating by rotating the specimen during the coating process.

      The substrate used for the sputter coating should withstand a temperature of around 500 C, as it warms up during the deposition process. A common flexible susbrtate that is used for this purpose is Kapton tape/sheet, which is also used in energy storage systems.

    To whom it may concern,

    I was wondering if you could provide me a cost estimate for your most simple (and cost-effective) sputter coater that can coat with multiple materials.
