Advantages of sputter coating for the specimen

Sputter Coater is the best method for organizing non- conducting specimens for inspection in a scanning electron microscope (SEM). The manual sputter coater is an ideal and systematic system for sample coating. It comes with Au of non- conducting samples for “standard SEM imaging”. The economical desktop have provided the benefits that you can reap, which offers rapid pump down times, fine grain coatings as well as fully variable current control. The safety is guaranteed, and the thickness monitor is highly suggested for precise measurements.

At applied physics, we offer a low cost system that would facilitate your work process. Carbon coater is designed for managing specimens for electron microscopy. The primary applications for carbon coating in Electron microscopy are X-ray microanalysis.

Cressington coater has been widely used where coating thickness has been consistency with high resolution coater. The Cressington 208HR caters a quick fix to the circumstances when coating difficult samples.

The main features for this product are:

Precision Thickness Control, Multiple sample stage movements, variable chamber geometry.

Electron microscopy has been widely used for examining objects that can’t be seen with human eye. Electron microscope focuses beams of electron that offers a higher magnification.

The electron microscopy must be well prepared before placing in the microscope vacuum. There are varieties of specimen and analysis that included fixation, dehydration, and cryofixation.

To achieve the optimum results during microscopy electron, it is required to have a clean and well- prepared specimens. The besmirch specimen can cause a detrimental effect on the electron microscope analysis.

Therefore, the plasma cleaner is designed to clean the hydrocarbon contamination. To get rid of hydrocarbon contamination a mixture of 25% of oxygen and 75% of argon is found to be the effective ones. It was reported that 25% of oxygen is effective in slashing down of hydrocarbon.

Benefits of Plasma cleaner for the electron microscopy

Plasma Cleaner is imperative tool for the electron microscopy, as it prevents contamination from occurring and removes any prior contamination from the specimen. There are several main causes of triggering this hydrocarbon contamination during specimen preparation. The standard method was not proven to be effective in impeding the contamination. Therefore, to achieve positive results during electron microscopy of semiconducting materials, it is significant to have a proper and clean specimen. This specimen borne besmirch can exacerbate the ability to conduct accurate electron microscope analysis.

It has been widely reported that oxygen plasma is highly recommended in eliminating hydrocarbon contamination. Foremost to remove the hydrocarbon contamination, a mixture of 25% of oxygen and 75% of argon is touted to be effective solution. Meanwhile, Electron microscope is a type of microscope that focuses a beam of electron. Electron microscope is proven to be highly effective due to greater magnifications that have a higher resolving power than any other microscope. The electron microscope plays an important role of many laboratories. The researcher has utilized the electron microscope to examine biological materials, a variety of molecules as well as other various surfaces.

The Cressington 108 sputter coaters are designed “for routine sample preparation”. The design is compact, economical and easy to operate. The Cressington 108 sputter coater provides the choice of manual and automatic operation.

Carbon coater is one of the most advanced and prevalent sample coaters. The 108C Auto carbon coater uses “a novel evaporation supply.” The supply renders stellar stability and replicability. Low consumption of power enables a better outcomes and the evaporation source can be functioned in “pulse” or “constant” modes.

The sputter coater designated to scanning electron microscopy to prevent charging of the specimen. At applied physics, we offer sputter coater which is an economical, compact and easy to operate, that would facilitate the work process. The customers will reap benefits of our sputter coater such as increase thermal conduction, reduced sample charging, as well as preserve beam sensitive specimens.
Meanwhile, carbon coater is designed to prepare specimens for electron microscopy – by evaporating high purify carbon fiber, and there is no need for expensive vacuum evaporators.
SEMI-KLEEN plasma cleaner offers a cleaning solution for contamination control, and has been proven for reducing the risk of ion sputtering damage.

SEMI-KLEEN_Plasma_Cleaner-s

SEMI-KLEEN Plasma Cleaner

SEMI-KLEEN plasma cleaner provides a gentle plasma cleaning solution for contamination control in high vacuum systems, such as SEM, FIB, AES, XPS, EBI, EBR, CD-SEM, etc.  It consists of a LCD touchscreen controller and a remote plasma source. Remote plasma source should be installed on the vacuum chamber to be cleaned.  Controller provides the RF power to the remote plasma source. It breaks down the process gas such as oxygen, hydrogen or other gas mixtures and generates reactive radicals. Radical species will then diffuse into the chamber to be cleaned and react with the contaminants. The byproducts are usually low molecule weight, high vapor pressure molecules that can be easily pumped away. Remote plasma cleaner can clean vacuum systems and samples at the same time.
