Laurell Technologies WS-400 spin coater used to apply photoresist to the surface of a silicon wafer. Spin coating is a procedure used to deposit uniform thin films onto flat substrates. Usually a small amount of coating material in liquid form is applied on the center of the substrate, which is either spinning at low speed or not spinning at all.
Aluminising vacuum chamber at Mont Mégantic Observatory used for re-coating telescope mirrors. [1] Vacuum deposition is a group of processes used to deposit layers of material atom-by-atom or molecule-by-molecule on a solid surface. These processes operate at pressures well below atmospheric pressure (i.e., vacuum). The deposited layers can ...
There are four basic parameters that are involved in spin coating: solution viscosity, solid content (density), angular speed, and spin time. [13] A range of thicknesses can be achieved by spin coating. Most commonly the thicknesses range from 1-200 μm. The main properties that affect the thickness of the film are viscosity and spin speed.

A fluid reservoir to store the main supply of coating fluid for the system; A pump to drive the coating fluid through the system; A slot-die to distribute the coating fluid across the desired coating width before coating onto the substrate; A substrate mounting system to support the substrate in a controlled manner as it moves through the system
Home Depot (NYSE: HD) is an obvious ... About 39% of flow sales (fluid treatment pumps and systems) go to the residential and agriculture sector. Meanwhile, about 33% of water solutions sales ...
It was the woman's mission to find the Dachshund a home before the holidays. And what better way to do so than by sharing a video of the dog in his kennel and giving him an introduction to the world.
Sputter coating in scanning electron microscopy is a sputter deposition process [clarification needed] to cover a specimen with a thin layer of conducting material, typically a metal, such as a gold/palladium (Au/Pd) alloy. A conductive coating is needed to prevent charging of a specimen with an electron beam in conventional SEM mode (high ...
