Abstract: This application relates to a fluid dispenser. In one aspect, the dispenser includes a body including an opening and an accommodating space for accommodating fluid, a lid for closing the opening, a pressing unit disposed on a side of the body, and a discharge unit disposed on the side at a position diagonally higher than the pressing unit and configured to discharge a predetermined amount of the fluid from the accommodating space when a pressure is applied to the pressing unit. The dispenser may also include a pump mechanism configured to pump the predetermined amount of the fluid from the accommodating space to the discharge unit when the pressure is applied to the pressing unit, and an air intake formed on a part of the lid and configured to flow air into the accommodating space when the predetermined amount of the fluid is discharged from the accommodating space.

Abstract: A spin dispenser module and methods for using the same is disclosed. The spin dispenser module includes a cup having a basin with sidewalls and an exhaust, a rotatable platform situated inside the cup adapted for holding and rotating a substrate, a liquid dispenser disposed over the rotatable platform for dispensing a liquid coating material on top of the substrate, one or more ejector inlets disposed over the rotatable platform, the one or more ejectors connected to a negative pressure source, and a motor coupled to the rotatable platform to rate the rotatable platform at different rotational speeds. The one or more ejector inlets may be translatable and/or rotatable with optionally adjustable suction pressure. The ejector inlets operate after a liquid coating material is dispensed to avoid deposition of suspended organic compounds after a coating is formed.
