Latest Patents

Dubash holds a patent for a "Methodology for in situ etch stop detection and control of plasma." This innovative method involves etching a dielectric layer to create a via to an underlying conductive layer. The process utilizes a plasma containing an etchant while monitoring electromagnetic energy from plasma emission radiation. This monitoring helps determine the ratio of specific species in the plasma, which indicates the onset of an etch stop phenomenon. The method allows for continued etching of the dielectric until the ratio of species exceeds a predetermined threshold value, at which point the process is halted, and the plasma reactor is cleaned. This technique is particularly useful for forming vias between conductive layers in integrated circuits.
