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.
