摘要： A spray coatable adhesive composition used for bonding silicon dies to a rigid substrate, preferable a silicon substrate is disclosed. The adhesive composition includes an epoxy based resin, a thermal acid generator, a photoacid generator and a solvent. The epoxy based resin includes a mixture of a solid bisphenol A epoxy resin and a liquid or semi-liquid hydrogenated bisphenol A epoxy resin at a weight ratio ranging from about 80:20 to about 65:35. The adhesive composition has a low viscosity which allows it to be spray coated on a rigid substrate and form thin film adhesive which allows silicon dies to be bonded with precise placement on the silicon substrate.

摘要： A method for improving adhesion between polymeric materials is provided. The method includes treating a surface of a first polymeric material with plasma of oxygen gas and hydrogen-containing gas. The first polymeric material may be a fully cured polymeric material. A second polymeric material may then be deposited on the plasma treated surface of the first polymeric material. The second polymeric material may be an uncured polymeric material. This plasma treatment may be used in improving the adhesion between polymeric components of an inkjet printer. It provides good adhesion between the polymeric components of the inkjet printer even after long exposure to ink.

摘要： Environmentally friendly thick film layers for a micro-fluid ejection head and micro-fluid ejection heads are disclosed. The environmentally friendly thick film layer includes a negative photoresist layer derived from a composition comprising a multi-functional epoxy compound, a low molecular weight polymeric difunctional epoxy compound, a monomeric difunctional epoxy compound, a methide-based photoacid generator that does not contain antimony, a chromophore and an aryl ketone solvent. Optionally the photoresist layer contains an adhesion enhancer. The negative photoresist layer is environmentally friendly and provides good resolution, well defined critical dimensions, straight side walls, and a large processing window.

摘要： A method of forming a patterned photoresist layer having a hydrophobic surface is provided. The method includes forming a photoresist layer on a substrate and image patterning. The photoresist layer may comprise a polymeric material. The imaged photoresist layer may then undergo a two-stage post-exposure bake. A surface treatment may be performed on the photoresist layer in between the two-stage post-exposure bake. The surface treatment may include applying a siloxane solution on a partially post-exposure baked photoresist layer. The post-exposure baked photoresist layer may then be developed to form the patterned photoresist layer. The method may be used to form a hydrophobic photoimageable nozzle plate of a micro-fluid ejection head having improved mechanical properties and stable hydrophobic properties.

摘要： A dynamic and flexible architecture and methods for demodulation of high data-rate streams with high symbol-rates, such as in satellite communications systems or computer network communications systems, is provided. A data stream of a data transmission is received, the data stream corresponding to a plurality of data symbols. A plurality of data samples corresponding to each of the data symbols is generated. Further, one or more representative data samples, corresponding each of the data symbols, are generated based at least in part on timing control signals and the generated data samples for the respective data symbol. The generated data samples corresponding to each of the data symbols other than the representative data samples are dropped. The timing control signals are then adjusted based at least in part on the generated representative data samples.
