Abstract:
Methods and products of Transport co-polymerization (nullTCPnull) that are useful for preparations of low Dielectric Constant (nullnullnull) thin films are disclosed. Transport co-polymerization (nullTCPnull) of reactive intermediates that are generated from a first precursor with a general structural formula (Z)mnullArnull(CXnullXnullY)n (VI) with a second reactive intermediate that is generated from a cage compound (e.g. Fullerenes, Methylsilsesquioxane, Hydrosilsesquioxane, and Adamantanyl) or a cyclic-compounds (e.g. Cyclo-Siloxanes and 2,2-Paracyclophanes) results in co-polymer films that are useful for making porous low null (null2.0) thin films. The porous thin films of this invention consist of nano-pores with uniform pore distribution thus retain high rigidity thus are suitable for manufacturing of future ICs using copper as conductor. Preparation methods and stabilization processes for low k co-polymers that consist of sp2CnullZ and HC-sp3CnullnullX bonds are also revealed. A preparation method is achieved by controlling the substrate temperature and feed rate of the major precursors. One stabilization process includes a post annealing of as-deposited co-polymer films under the presence of hydrogen under high temperatures. The reductive annealing of these films is conducted at temperatures from null20null C. to null50null C. to null20null C. to null50null C. of their Reversible Crystal Transformation (nullCRTnull) temperatures, then quenching the resulting films to null20null C. to null50null C. below their nullCRTnull temperatures. The reductive annealing is conducted before the as-deposited film was removed from a deposition system and still under the vacuum. nullRe-stabilizationnull processes of co-polymer surfaces that are exposed to reactive plasma etching are also disclosed; thus, further coating by barrier metal, cap layer or etch-stop layer can be safely applied.

In the present invention, the starting material represented by the following structural formula (I) is evaporated and heated to bring the material into monomer form. The material is then introduced into a vacuum deposition chamber maintained at a predetermined degree of vacuum wherein the material is deposited and polymerized on a substrate to obtain the polymer thin film. This polymer thin film is also used in producing the bio chip. 1 wherein R11 and R12 independently represent nullCH2NH2 group or H, and at least one of the R11 and R12 is nullCH2NH2 group.
Abstract:
Pellicles of para-xylylene polymers are used as the sole support media for masses of objects supported thereon. The supported objects can be combined with the pellicle either during the formation of the pellicle or after the pellicle has been manufactured. The composite article is used wherever it is desirable to provide a support media which has as little detrimental influence as possible on the intended function of the supported object.
