    Abstract: The invention relates to fabrication of a high resolution patterned structure on a polymer layer with accurate alignment, for the manufacture of an electrochemical cell. A polymer layer 204 is deposited on a substrate 200 and an embossing tool is used to stamp the polymer layer. The embossing tool has an array of protrusions extending from the stamping face, which after stamping form an array of adjacent cavities within the embossed polymer layer separated by an array of banks 153, giving adjacent cells of the device. A metal oxide is subsequently deposited in the cavities. Polymer material remaining in the cavity bottoms may be removed to expose an electrode layer 202 underlying the polymer layer. In one embodiment, a gold layer is evaporated on a polymer layer and both layers are stamped simultaneously (see fig 6).

    Abstract: A self-assembled monolayer (SAM) is fabricated using either a semi-fluorinated sulphur containing compound or a semi-fluorinated silane derivative and compressed carbon dioxide as the solvent medium. The temperature and/or pressure of the compressed CO Þ may be varied during the fabrication process to improve the molecular packing density of the monolayer. The substrate may be metallic e.g. Au, Ag, Cu, Pd, Fe, Hg, GaAs, ITO, or Fe Þ O ý or may be glass or silicon. A co-solvent such as H 2 O, CH ý OH, CF ý OH, CF ý CH Þ OH, CF ý CF Þ OH, (CF ý ) Þ CHOH, CH Ú , C 2 H Ú , C Þ F Û , CHF ý , CClF ý , C 2 H Û , SF Û , propylene, propane, NH ý , pentane, PrOH, MeOH, EtOH, BuOH, benzene and pyridine may be used in combination with the compressed carbon dioxide. The self assembled monolayer may be used in an inkjet head, an electronic, optical or an optoelectronic device such as a thin film transistor, an organic semiconductor device or a light emitting diode.

    Abstract: A dendron 2 comprising a focal point 4 and a plurality of fluorinated end groups 9. The dendron may have a thiol, silane, carboxylic acid, phosphonate or other suitable moiety at the focal point suitable for chemisorption to a substrate (3). Typical substrates 3 include a metal, glass and silicon type substrates. A thiol is the preferred moiety at the focal point. Preferred fluorinated dendron thiols are formed with a decane chain extending from the focal point to one or more di- or trihydroxybenzyl units forming branching points. The hydroxyl groups of the outermost benzyl units forming phenol ethers with perfluoroalkyl terminating groups (e.g CF3(CF2)5(CH2)4 and CF3(CF2)9(CH2)4) on the outer hydroxyl groups. A self-assembled monolayer (SAM) comprising a plurality of dendrons bonded to a suitable substrate, the formation of a monolayer, and devices such as ink jet print heads featuring these SAMs are also outlined.
