Nitrogen Purge
Nitrogen purge is widely employed in the manufacturing of semiconductors. It is utilized to establish a low-oxygen setting for processing substrates. This method helps remove impurities, minimize oxidation, maintain uniform film deposition, and can be beneficial for meeting safety standards. Nitrogen Purge Nitrogen purge is a common technique used in various industries, including semiconductor manufacturing, […]
Bake Plate Process Theory
Hotplate baking is a popular technique for film drying and curing, offering advantages over traditional convection ovens such as decreased bake time, increased uniformity, reproducibility, and decreased particle contamination. Hotplate baking heats the substrate from the bottom up, preventing the formation of a skin on the film surface and offering advantages for thick films. Bake […]
Spin Chucks for Square Substrates
Spin-coating is a process used to evenly distribute material on a substrate by spinning it at a high speed. Round substrates are commonly used because their smooth edges create minimal turbulence, resulting in uniform evaporation rates. However, square and rectangular substrates create unique challenges due to increased air turbulence and can result in uneven coating […]
