  • Patent number: 11754923
    Abstract: In a method, a resist material is dispensed through a tube of a nozzle of a resist pump system on a wafer. The tube extends from a top to a bottom of the nozzle and has upper, lower, and middle segments. When not dispensing, the resist material is retracted from the lower and the middle segments, and maintained in the upper segment of the tube. When retracting, a first solvent is flown through a tip of the nozzle at the bottom of the nozzle to fill the lower segment of the tube with the first solvent and to produce a gap in the middle segment of the tube between the resist material and the first solvent. The middle segment includes resist material residues on an inner surface wall of the tube and vapor of the first solvent. The vapor of the first solvent prevents the resist material residues from drying.

The first dielectric layer is thereafter patterned to form a mask overlay alignment mark in the overlap region. The patterning includes etching the first dielectric layer form a trench, and filling the trench with a conductive material to produce the alignment mark. A second dielectric layer is deposited over the alignment mark, and a second photoresist is deposited over the second dielectric layer.

The first crosslinker is a monomer, oligomer, or polymer. The second crosslinker is a monomer, oligomer, or polymer. The first and second crosslinkers are different from each other. When either of the first crosslinker or the second crosslinker is a polymer, the polymer is a different polymer than the carbon backbone polymer.
