Spin Coating and Film Coating Machine

A spin Coater uniformly spreads the liquid adhesive dropped at the center of the substrate into a thin film by rotating the substrate at high speed and utilizing centrifugal force. This equipment is used to prepare uniform coatings with controllable thickness on planar substrates and is suitable for photoresist coating processes on surfaces such as semiconductor wafers and optical lenses.
Selection
When selecting a spin Coater, it is essential to consider the compatibility between the substrate size and the fixture, ensuring the rotational speed range covers the required film thickness process, as acceleration and deceleration control affect coating uniformity. Attention should also be paid to the stability of the vacuum adsorption system, the programmable control functions to accommodate different colloidal characteristics, and the protective design to meet the requirements of the actual operating environment.
