    Abstract: New protective coating layers for use in wet etch processes during the production of semiconductor and MEMS devices are provided. The layers include a primer layer, a first protective layer, and an optional second protective layer. The primer layer preferably comprises an organo silane compound in a solvent system. The first protective layer includes thermoplastic copolymers prepared from styrene, acrylonitrile, and optionally other addition-polymerizable monomers such as (meth)acrylate monomers, vinylbenzyl chloride, and diesters of maleic acid or fumaric acid. The second protective layer comprises a highly halogenated polymer such as a chlorinated polymer which may or may not be crosslinked upon heating.

    Abstract: New compositions and methods of using those compositions as bonding compositions are provided. The compositions comprise a polymer dispersed or dissolved in a solvent system, and can be used to bond an active wafer to a earner wafer or substrate to assist in protecting the active wafer and its active sites during subsequent processing and handling. The compositions form bonding layers that are chemically and thermally resistant, but that can also be softened to allow the wafers to slide apart at the appropriate stage in the fabrication process.FIGURE 1

    Abstract: A novel process for using a hard mask or protective layer in conjunction with an extremely thin photoresist is provided. In this process, a thin film of the protective layer is coated on the surface of a substrate that is to be selectively modified by reactive ion etch (RIE). The protective layer is photosensitive and anti-reflective. An extremely thin photoresist layer is coated on top of the protective layer. The stack of the films is selectively exposed to actinic radiation at a wavelength determined by the sensitivities of the protective layer and photoresist layer. The latent images on the photoresist and protective layers resulting from the exposure are developed with a common alkaline developer. The three dimensional patterns of photoresist and underlying protective layer are formed simultaneously by the single exposure and single development. When the underlying substrate is etched by RIE, the protective layer is the masking layer, not the photoresist.
