Electron Microscope Invention: A Historical Overview

[vc_row][vc_column width="3/4"][vc_row_inner][vc_column_inner][vc_column_text] History of Electron Microscope (1930-1980) Nowadays, the electron microscope is an essential instrument to characterize new structures and materials and electron microscope invention has become a popular topic for scientific research. In a typical electron microscope a beam of electrons is focused upon a target specimen. Information is often gathered from electrons transmitted through or scattered from the specimen by Bragg diffraction, alongside data gathered from Auger electrons, characteristic x-rays, and the charge absorbed by the specimen. On the basis of particle-wave duality theory of de Broglie, electrons can replace photons in a microscope to improve the image resolution more than 5000 times.

What is RF Sputtering? | DC vs RF Sputtering

Report, Sputter Coater, Sputtering

[vc_row][vc_column width="3/4"][vc_row_inner][vc_column_inner width="1/2"][vc_column_text css=""] Why RF Magnetron Sputtering? Direct current (DC) sputtering is a cost-effective method for thin layer deposition of electrically conductive metallic targets. But this method is not applicable for non-conductive dielectric target materials, since bombarding such targets with positive ions causes charging the surface of the target, which repels further positive ion bombarding the surface, resulting in the cessation of sputtering process and arcing into the plasma. In order to overcome DC sputtering shortcomings, RF sputtering is widely used for electrically non-conductive target materials deposition.

Effect of Chamber Ultimate Pressure on Carbon Coating

Carbon Coater, Report

[vc_row][vc_column width="3/4"][vc_row_inner][vc_column_inner][vc_column_text] Effect of Chamber Ultimate Pressure on Carbon Coating Electron microscopy is a method to image samples, which provides much higher resolution and further details compared to traditional optical microscopes. Samples should be conductive for this analysis, so a conductive layer is normally deposited on the sample surface to image nonconductive surfaces. Carbon is one of the common materials used for sample preparation for electron microscopy, but carbon coating needs a vacuum chamber to reach required conductivity [1].

Balanced and Unbalanced Magnetron Sputtering

Report, Sputter Coater, Sputtering

[vc_row][vc_column width="3/4"][vc_row_inner][vc_column_inner][vc_column_text] Balanced and Unbalanced Magnetron Sputtering Sputtering was first introduced in 1852 and was used by a person named Groe. He could using an electrical discharge deposited the metal film on a cold cathode. At first, sputtering was used for deposition of the refractory metals film, whose deposition was not possible by thermal evaporation, but gradually, using radio frequency waves (RF Sputtering), the possibility of dielectric films was also provided by the sputtering deposition method.

Unbalanced Magnetron Cathodes

Report, Sputter Coater, Sputtering

[vc_row][vc_column width="3/4"][vc_row_inner][vc_column_inner][vc_column_text] Unbalanced Magnetron Sputtering Cathodes Balanced and unbalanced magnetron cathodes in sputtering systems have their advantages and disadvantages as mentioned in “balanced and unbalanced magnetron sputtering” article. What is Unbalanced Magnetron? Balanced magnetic fields with magnetic field lines confined around the cathode, limit the charged colliding particles (electron-ions) to the target surface which benefits low friction coatings; whereas in an unbalanced magnetron with some magnetic field lines toward the substrate, the ions bombard the thin film, affecting thin film surface morphology and adhesion to the substrate, suitable for pre-cleaning and hard coatings. Since balanced cathodes are common, here we discuss the unbalanced magnetron cathodes and theirs specifications.

Effect of Base Pressure on Thin Film Grain Size in Sputtering

[vc_row][vc_column width="3/4"][vc_row_inner][vc_column_inner][vc_column_text] Effect of Base Pressure on Thin Film Grain Size in Sputtering Sputter coating of thin films is operated in a vacuum chamber, where pressure is much lower than atmosphere environment, to reduce the air contaminants in the chamber and have a cleaner thin film. Pure argon purge into the chamber also helps to remove residual air and increase sputtering deposition rate. As the chamber is evacuated before argon purge, various contaminants of the environment like nitrogen, oxygen, carbon dioxide, and water vapor get out of the chamber gradually, where water vapor is the greatest barrier toward reaching higher vacuum levels.

Cu Thin Films by DC Magnetron Sputtering

[vc_row][vc_column width="3/4"][vc_row_inner][vc_column_inner][vc_column_text] Electrically Conductive Cu Thin Films by DC Magnetron Sputtering Many studies focus on the growth of copper microstructure as a function of the coating method. The increase of resistivity of copper thin films is due to various phenomena such as scattering from defects (vacancies, dislocations, grain boundaries) and also scattering from the free surface, bottom interface, and side-wall interfaces of the films. In this way, the mean free path of electrons decreases, which leads to an increase in resistance.
