Latest Patents

One of Kari Hansen's latest patents is the "Bottom antireflection coating color filter process for fabricating solid state image sensors." This patent describes an image sensor system that includes a color filter array formed by a process incorporating a bottom antireflection coating. This coating serves as a protective layer for the active image sensing device structure during the formation of the color filter array. It preserves the intrinsic transmission characteristics of the device and reduces degradation of metal structures, such as bonding pads and pixel edges. Additionally, the bottom antireflection coating provides a reliable adhesive surface for the color filter array, significantly minimizing the risk of lifting of the resist structures. In some embodiments, it also enhances the optical transmission characteristics of various colors in the filter array.
