Creating thin films using different deposition methods is the basis of many industries. As a simple example, consider a mirror that reflects light with a layer of metal which deposited behind the glass. The development of deposition methods in the last century has led to the development of many industries, including semiconductor electronics, magnetic recording media, integrated circuits, LEDs, optical coatings (such as anti-reflective coatings), hard coatings in order to protect tools, pharmaceuticals, medicine and many other industries.…

Upgrading the Sample Planetary Rotation System

Sputter Coater, Sputtering, Thermal evaporation, Thin Film

[vc_row][vc_column][vc_single_image image="3380" img_size="large" alignment="center" onclick="link_image"][/vc_column][/vc_row][vc_row][vc_column width="1/4"][vc_wp_posts number="10"][/vc_column][vc_column width="3/4"][vc_column_text] Upgrading the Sample Planetary Rotation System One of the characteristics of a suitable thin film is the degree of uniformity of the deposited layer. Rotation of the substrate during coating is one of the most effective ways to increase the uniformity of thin film deposited in the Physical Vapor Deposition (PVD) method. The effectiveness of substrate rotation in improving the uniformity of the deposited thin film depends on the geometry of the substrate and how it rotates during the coating process. For example, in the case of substrates with a flat geometric shape (such as a disk), rotation about an axis perpendicular to the surface of the substrate is sufficient to create a uniform layer on it. However, for more complex geometric…

The most common methods of PVD are Sputtering and Thermal Evaporation. Because in the PVD process, the material is transported and accumulated atom-by-atom or molecule by molecule in a vacuum to the substrate surface, the deposited films have high purity and efficiency that for many applications compared to other deposition methods are preferred. For example, in the construction of the most important part of any microchip and semiconductor device, durable protective layers, optical lenses, solar panels and many parts and medical devices, the PVD thin film provides…

In order to reduce the incomplete bonds of surface atoms, surfaces are active sites for the adsorption of gases and vapors that are released from the surface when placed in a vacuum. This means that all surfaces, regardless of the type of material, have Outgassing. The four…

In this deposition method, the desired surface(substrate) is exposed to the vapor of one or more chemicals. Then, in order to create a solid layer with the desired chemical composition, the gas atoms in the chamber decompose on the surface of the substrate or react with each other chemically. This deposition method is classified in different ways depending on what chemical method it starts with.

The created layer deposits as a coating on a surface and changes the properties of the substrate surface depending on the application. The thickness of the deposited layers in this process, depending on the coating method and the type of material, can be in the range of one atom(nanometer) to several millimeters. There are several methods for creating a layer of different materials on different surfaces such as spraying, spin coating, plating and vacuum deposition methods that are performed from the vapor phase of the target material. In the following, we will introduce some deposition methods:…

Electron microscopy (EM) is a technique for obtaining high-resolution images of biological and non-biological samples. Electron microscopy is used in biomedical research to examine the exact structure of tissues, cells, organs, and macromolecular complexes. The high resolution of electron microscope images is due to the use of electrons as radiation sources. Electron Microscope vs Optical(light) Microscope Because the wavelength of an electron beam is 100,000 times shorter than the wavelength of visible light photons, electron microscopes have far greater detection power than light microscopes. These microscopes can provide a structural image of the smallest objects with a resolution better…

Rotary pumps usually have many applications in industry due to their ability to work for a long time in industrial and difficult conditions. So rotary pumps maintenance is very important. Almost all vacuum coating systems made by VacCoat Ltd. are equipped with two-stage rotary pumps. In models such as DST3, DST1, DCT, etc., which use turbomolecular pumps to create a high vacuum environment, these pumps are usually used as backing pumps. Rotary Vacuum Pumps Rotary Vacuum Pumps are in the group of displacement pumps and are of the positive displacement type. This means that for each pump cycle, a constant volume of fluid is displaced, regardless of the pump pressure resistance. As a result,…
