SPUTTERING

Sputter Coating principle for use in Scanning Electron Microscopy

It has been indicated that under conditions of glow discharge, ion bombardment of the cathode will occur. This results in the erosion of the cathode material and is termed plasma sputtering, with the subsequent omni-directional deposition of the sputtered atoms forming coatings of the original cathode material on the surface of the sample and work …

Sputter Coating for SEM: How This Sample Preparation Technique Assists Your Imaging?

Scanning electron microscopes (SEMs) are versatile tools that can provide nanoscale-level information about a wide range of samples with little or no sample preparation. In some cases, however, sputter coating the samples before working with SEMs is necessary to obtain a good-quality SEM image. SEMs can image all kinds of samples: ceramics, metals and alloys, semiconductors, polymers, biological …

SPUTTERING

SPUTTERING is a widely used and highly versatile vacuum coating system used for the deposition of a variety of coating materials. Plasma at higher pressure is used to “knock “metal atoms out of a “target”. These energetic atoms deposit on a wafer located near the target. The higher pressure produces better step coverage due to …
