Latest Patents

Darlington holds a patent for a "Process for forming a semiconductor device." This patent describes a method for creating via openings between two aluminum-containing interconnects. The process involves removing a veil material formed during the etching of an insulating layer. The veil material is eliminated through a combination of a first dry etch and exposure to an aqueous organic solvent. The first dry etch utilizes oxygen-containing and fluorine-containing gases, performed during the resist removal phase. This method effectively removes the veil without damaging the insulating layer or the underlying aluminum interconnect. Additionally, the temperature of the aqueous organic solvent can be reduced, which decreases volatile organic compound emissions while maintaining solvent strength.
