  • Stabilized etching solutions for CU and CU/NI layers
    Patent number: 8652972
    Abstract: The present invention relates to new storage-stable solutions which can be used in semiconductor technology to effect specific etching of copper metallization layers and also Cu/Ni layers. With the new etch solutions it is possible to carry out etching and patterning of all-copper metallizations, layers of copper/nickel alloys, and also successive copper and nickel layers.
