    Abstract: BIOBASED CROSS-LINKED COMPOSITIONS, METHODS OF FABRICATION AND STRUCTURES, IN PARTICULAR BIOBASED PRINTED WIRING BOARDS USING THE COMPOSITIONS AND METHODS OF MAKING THE STRUCTURES ARE DESCRIBED. BIOBASED MATERIALS SUCH AS LIGNIN, CROP OILS, WOOD RESINS, TANNINS, AND POLYSACCHARIDES AND COMBINATIONS THEREOF ARE CROSS-LINKED, PREFERABLY USING HEAT, A CROSS-LINKING AGENT, AND AN INITIATOR. THE MATERIALS FABRICATED HAVE SUITABLE PROPERTIES FOR PRINTED WIRING BOARDS WHICH ARE MADE BY IMPREGNATING A FIBERGLASS OR BIOBASED CLOTH WITH AN ADMIXTURE OF THE BIOBASED MATERIAL, CROSS-LINKING AGENT AND INITIATOR WHICH IS PROCESSED BY CONVENTIONAL METHODS TO PRODUCE A PRINTED WIRING BOARD.

    Abstract: Improved chemically amplified negative tone microlithographic resist compositions and methods for the use thereof are disclosed. The compositions comprise, in admixture, a crosslinking agent, a polymeric binder, and a compound that generates acid upon exposure of the resist composition to imaging radiation. The invention is particularly related to compositions having a crosslinking agent which does not plasticize the polymeric binder or alternatively does not reduce the glass transition temperature thereof. This minimizes the diffusion of the acid component from exposed regions of the resist to unexposed regions, and helps maintain relief image dimensional control.

    Abstract: A method and apparatus are disclosed for conducting a physical process and a chemical reaction by exposing a material containing a volatile substance to microwave radiation where the morphology of said material will change when exposed to such radiation. The power of said radiation is adjusted over time as the morphology of the material changes to maximize the effect of the radiation in order to produce a product in a minimum amount of time that is substantially free of said volatile substance. The method and apparatus can also be used to conduct such a process or reaction with materials that do not contain a volatile material. In one embodiment a method and apparatus are disclosed for manufacturing a polyimide from a precursor in a solvent by exposing the precursor to microwave radiation in a tuneable microwave resonant cavity (2) that is tuned during imidization to achieve critical coupling of the system. Microwave power is controlled to remove the solvent and obtain the desired level of reaction.
