A developer tool described herein includes a dispenser that includes a greater quantity of nozzles in a central portion relative to a perimeter portion such that the developer tool is capable of more effectively removing material from a photoresist layer near a center of a substrate (which tends to be thicker near the center of the substrate relative to the edge or perimeter of the substrate). In this way, the developer tool may reduce the amount of photoresist residue or scum remaining on the substrate near the center of the substrate after a development operation, which may enable defect removal and/or prevention, may increase semiconductor processing yield, and/or may increase semiconductor processing quality.

Semiconductor developer tool and methods of operation

A method includes providing a first plate including a first surface, a second surface opposite to the first surface, and a first recess indented from the first surface towards the second surface; providing a semiconductor structure including a third surface, a fourth surface opposite to the third surface, and a first sidewall extending between the third surface and the fourth surface; placing the semiconductor structure over the first plate; and disposing a priming material over the third surface of the semiconductor structure, wherein a peripheral portion of the fourth surface of the semiconductor structure is in contact with the first surface of the first plate upon the disposing of the priming material.

Method of manufacturing semiconductor structure

A resist material dispensing system includes a resist supply and a resist filter connected to the resist supply downstream from the resist supply. The resist material dispensing system includes a resist tank structure connected to the resist filter downstream from the resist filter and a resist pump device connected to the resist tank structure downstream from the resist tank structure. The resist tank structure is vertically arranged so that a resist material flows in a continuous downward flow from where the resist material enters the resist tank structure until the resist material exits the resist tank structure.

Resist pump buffer tank and method of resist defect reduction

A lithography includes a storage tank that stores process chemical fluid, an anti-collision frame, and an integrated sensor assembly. The storage tank includes a dispensing port positioned at a lowest part of the storage tank in a gravity direction. The anti-collision frame is coupled to the storage tank. An integrated sensor assembly is disposed on at least one of the anti-collision frame and the storage tank to measure a variation in fluid quality in response to fluid quality measurement of fluid.

Liquid storage for facility chemical supply system

The present disclosure provides an apparatus for fabricating a semiconductor structure, including an air flow redistribution member configured to receive an air flow at a first end and eject the air flow at a second end. The air flow redistribution member includes a first air flow redistribution plate and a second air flow redistribution plate between the first air flow redistribution plate and the second end.

Semiconductor apparatus and method for baking coating layer

The present disclosure provides a method for forming a masking layer, including spinning a wafer, dispensing a first liquid at a first location on the wafer, and dispensing a second liquid at a second location on the wafer simultaneously with dispensing the first liquid at the first location, wherein the second liquid is a remover of the first liquid, and the first location is different from the second location.

Apparatus for forming a photoresist layer, method for forming a masking layer, and method for forming a photoresist layer

The present disclosure provides an apparatus for dispensing liquid material, including a dispensing arm, a wafer holder against the dispensing arm, a first nozzle on the dispensing arm, a first distance laterally spacing the first nozzle and a center of the wafer holder, and a first height vertically spacing the first nozzle and a surface of the wafer holder, and a second nozzle on the dispensing arm, a second distance laterally spacing the second nozzle and the center of the wafer holder, and a second height vertically spacing the second nozzle and the surface of the wafer holder, wherein the second distance is greater than the first distance, and the first height is greater than the second height.
