Latest Patents

Craig Y Nakakura holds a patent for a plasma-based method for delayering circuits. This invention relates to methods of delayering a semiconductor integrated circuit die or wafer. The method includes exposing a die or wafer to plasma of an etching gas and detecting exposure of one or more metal layers within the die. In one aspect of the invention, the plasma of the etching gas is non-selective and removes all materials in a layer at about the same rate. In another aspect, two different plasmas of corresponding etching gases are employed, with each plasma being selective, necessitating the sequential use of both plasmas to remove all materials in a layer. This innovative method has the potential to streamline semiconductor processing and improve overall production quality.
