DuPont introduced its newest offering for semiconductor fabrication, DuPont WB Series dry film photoresist for wafer bumping at the IMAPS 2003 last November. DuPont will feature WB Series resists in conjunction with its latest developments in thick film and low-temperature co-fired ceramic (LTCC) technologies and other microcircuit materials.

DuPont WB dry film photoresist is an attractive alternative for wafer bumping vs liquid resists. Thick photoresist (from 50 to over 100 μm) is applied in one step, with no solvents or drying required. The result is fewer overall process steps, and exact thickness uniformity from edge-to-edge of the wafer can be achieved, irrespective of the wafer size is being produced.
