Spin Coating of Photoresists
During coating, the solvent concentration drops and saturates at a value of approx. 15-25 % which depends on the film thickness and is higher for thicker films. The subsequent softbake re-duces the remaining solvent concentration to values of typ. 5 %. A high ambience solvent saturation in the spin coater reduces the attained resist film thick ...

Resist Spray Coat (manual) | Stanford Nanofabrication Facility
Resist can be aerosolized and sprayed through a nozzle that sweeps across a substrate. The advantage of spray coating is that, in contrast to spin coating, high aspect ratio features such as tall pillars or deep trenches, can be fully and uniformly coated. In contrast, coating high aspect ratio features is a shortcoming of spin-coating; centrifugal forces …

Photoresist spin coating mechanism related to polymer
Spin coating has long been accepted as the best coating method for obtaining a thin (0.2-2 pm), uniform, adherent, homogeneous film over the wafer. It is accomplished by flooding the substrata with a polymer solution and rotating it at a constant speed (1000-8000 rpm) until the solvent has evaporated. For a given polymer solution …

UV photoresist (PR) refers to a PR sensitive to a wavelength between 280 nm and 450 nm. According to the wavelength of light, it can be classified into UV broadband, G-line (436 nm), and I-line (365 nm) PRs. The resolution of I-line PR can reach 0.35 μm, which is the workhorse in microelectronics and ICs.

Spin coating and wafer development
Spin coaters are capable of applying uniform thickness polymer films, such as a resist to substrates. Resist is essential for many types of lithography, such as UV lithography. Resists are termed either positive or negative — this denotes whether, when cured, chemical bonds are made or broken, and therefore whether the sections of resist that …
