  • Patent number: 7101652
    Abstract: New photosensitive PBO precursor polymers which contain diazoquinone moieties attached to its backbone and in which all amino end groups are converted into amide groups. The photosensitive formulation based on the disclosed PBO precursor polymers have good imaging and mechanical properties as well as superior shelf life stability. Photosensitive polybenzoxazole precursor polymers having (sulfon)amide end groups (with or without attached diazoquinone groups) can be formulated into photosensitive compositions with diazoquinone photoactive compounds which lack benzylic hydrogens on the backbone to yield compositions producing films significantly lighter in color after curing.

  • Patent number: 7011935
    Abstract: Processes to overcome mistakes, such as, incorrect film thicknesses, poor coating quality, and incorrect feature dimensions made during the lithographic process in multilayer imaging systems are provided. To optimize manufacturing efficiency, it is desirable to be able to remove the top layer (an imaging layer) without having to remove, recoat, and usually cure the bottom layer (undercoat or underlayer). A rework process for removing an imaging layer from a substrate stack is such a process. The stack comprises a substrate, an underlayer adjacent to the substrate, and an imaging layer comprising silicon adjacent to the underlayer.
