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.
Laptop hard drive platters are made from glass while aluminum platters are often found in desktop computers. [14] [15] In disk manufacturing, a thin coating is deposited on both sides of the substrate, mostly by a vacuum deposition process called magnetron sputtering. The coating has a complex layered structure consisting of various metallic ...
Spin is a multitasking high-level computer programming language created by Parallax's Chip Gracey, who also designed the Propeller microcontroller on which it runs, for their line of Propeller microcontrollers. [5] Spin code is written on the Propeller Tool, a GUI-oriented software development platform written for Windows XP. [6]
Spin network diagram, after Penrose In physics , a spin network is a type of diagram which can be used to represent states and interactions between particles and fields in quantum mechanics . From a mathematical perspective, the diagrams are a concise way to represent multilinear functions and functions between representations of matrix groups .
The first self-cleaning glass was based on a thin film titania coating. [3] The film can be applied by spin coating of organo-titanate chelated precursor (for example titanium iso-tetrapropoxide chelated by acetylacetone), followed by heat treatment at elevated temperatures to burn the organic residues and to form the anatase phase.
Electrospinning can also be used for medical purposes. [64] The electrospun scaffolds made for tissue engineering applications can be penetrated with cells to treat or replace biological targets. [65] Nanofibrous wound dressings [66] have excellent capability to isolate the wound from microbial infections.
SU-8 molecule. SU-8 is a commonly used epoxy-based negative photoresist.Negative refers to a photoresist whereby the parts exposed to UV become cross-linked, while the remainder of the film remains soluble and can be washed away during development.
Spin glass when contrasted with a ferromagnet is defined as "disordered" magnetic state in which spins are aligned randomly or without a regular pattern and the couplings too are random. [1] A spin glass should not be confused with a "spin-on glass". The latter is a thin film, usually based on SiO 2, which is applied via spin coating.
