HD7110 series are wide range curable and solvent developable Nega-tone type Polyimide precurcer. This product based on Industrial standard HD4100series. Low temperature curing is effective in reducing wafer stress and warpage. The HD7110 achieves high flatness, high insulation reliability, and high resolution and is effective for forming high-density design used in advanced packages. It can also be used for general stress buffer applications.
