Latest Patents

Jim Bowers holds a patent for a process titled "Plasma etching of organic antireflective coating." This invention involves a semiconductor manufacturing process where an organic anti-reflective coating (ARC) is plasma etched with selectivity to an underlying dielectric layer and/or overlying photoresist. The etchant gas used in this process is fluorine-free and includes a carbon-containing gas such as CO gas, a nitrogen-containing gas such as N, an optional oxygen-containing gas such as O, and an optional inert carrier gas such as Ar. The etch rate of the ARC can be at least 10 times higher than that of the underlying layer. By utilizing a combination of CO and O with N and a carrier gas such as Ar, it is possible to achieve dielectric:ARC selectivity of at least 10. This process is particularly useful for etching contact or via openings in damascene and self-aligned contact or trench structures.
