Latest Patents

Richard A. Bickford holds a patent for a methodology that enhances the etching process of dielectric layers. This patent describes a method of etching selected portions of a dielectric layer to form a via to an underlying conductive layer. The process involves monitoring electromagnetic energy from plasma emission radiation to determine the ratio of species in the plasma, which indicates the onset of an etch stop phenomenon. The etching continues until the ratio of species exceeds a predetermined threshold value, at which point the process is halted, and the plasma reactor is cleaned. This method can be particularly useful in forming vias between conductive layers in integrated circuits.
