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.
Spin casting is a favored method for fabricating items in the specified materials – low temperature metals and thermoset plastics. Compared to the two main competing processes, injection molding and (zinc) die-casting, spin casting has significant advantages in terms of startup cost and ease of use.
For example, a whole car has been coated with spray assembly, optically transparent films have been prepared with spin assembly, etc. [1] Characterization of LbL film deposition is typically done by optical techniques such as dual polarisation interferometry or ellipsometry or mechanical techniques such as quartz crystal microbalance.
Detailing is more than a cleaning process to make a vehicle look good; it is a systematic approach to help extend its life with methods and products that reduce damaging environmental elements such as dirt, sun, harsh winters, etc. [3] Appropriate maintenance or restoration of vehicles to keep them looking outside and inside as if they came from an auto dealer's showroom increase their resale ...
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.
The new rules include restrictions on the sale of of high bandwidth memory chips, which are critical for high-end applications such as generative AI training, plus fresh software and technology ...
GM's CFO told investors the company has changed its business strategy to withstand market volatility and a new presidential administration.
He had no living family. He was not famous. He lived alone. Yet on Tuesday, hundreds of people gathered at the graveside of World War II veteran Stephen Kolesnik Jr. and watched him laid to rest.
