Abstract: A method for synthesizing conjugated polymer by plasma polymerization, which comprises the steps of introducing at least one monomer at a high concentration into a vacuum chamber; and igniting plasma, wherein the monomer is shattered into preferable-size fragments and is activated, and the activated monomers polymerize or copolymerize with one another to form the conjugated polymer.

Abstract: A method of forming a nozzle plate of an inkjet print head. A silicon chip is provided with an activated device and a first film is formed on the silicon chip, with a first opening corresponding to the activated device. Then, a second film is formed on the first film. Next, a photoresist layer is formed on the second film, such that the photoresist layer has a second opening corresponding to the first opening. Next, the second film under the second opening of the photoresist layer is etched to form a via in the second film passing through the first opening.

Abstract: An inkjet printhead chip is installed at the nose of an ink cartridge. Its structure includes a silicon substrate, a barrier layer, and a nozzle plate. The nozzle plate is formed with two parallel rows of inkjet nozzles. Two rows of ink channels roughly parallel to the inkjet nozzles and two rows of independent control circuits are provided among the silicon substrate, the barrier layer and the nozzle plate. The ink channels are disposed between the two rows of nozzles. The control circuits are configured to be on the outer sides of the two rows of nozzles. Using this structure of ink channels and control circuits, the inkjet printhead chip allows a larger area for attaching the nozzle plate. A flexible printed circuit is used to send external control signals from both sides of the chip to the control circuits, starting ink firing elements to eject ink and form patterns or texts on a nearby medium.

Abstract: A method in accordance with present invention comprises the steps of: forming a micro-control apparatus having a plurality of ejecting elements; forming a first layer of film on said micro-control apparatus and forming a plurality of ink chambers in the first layer of film; forming a second layer of photosensitive film on said first layer of film and forming an ink orifice in said second layer of photosensitive film relative to each of said plurality of ink chambers in the first layer of film by photolithography. The method for manufacturing the printhead in accordance with the present invention is relatively simple. Using this method, the application of a nozzle plate to a dry film photoresist and the precision alignment between ink orifices and ink chambers in manufacturing a conventional printhead can be avoided so that the throughput and yield rate can be increased.

The process includes steps of: a) providing a substrate, b) forming a dielectric layer over the substrate, c) forming a resistor over the dielectric layer, d) forming a conducting layer over a portion of the resistor, e) forming a passivation over a portion of the conducting layer and another portion of the resistor not covered by the conducting layer, f) forming a hole over the passivation for storing an ink, and g) forming a nozzle over the hole for ejecting therethrough the ink.

Abstract: The ink-jet cartridge of the present invention includes two magnetic plates attached to the two sides of a flexible ink reservoir and facing each other with their sides of the same magnetic polarity. Alternatively, the two magnetic plates are attached to two flexible bags within the rigid ink reservoir and face each other with their sides of the same magnetic polarity. Due to the repulsive force generated by the two magnetic plates, a pressure regulating effect can be achieved within the ink reservoir to prevent ink leakage and provide smooth ink delivery while printing.

Abstract: A fragrant ink is provided. The fragrant ink comprises an alcohol component, an imaging component, a fragrant agent component, and a deionized water component. In certain embodiments, the fragrant ink further comprises an ethanol component. The imaging component includes at least one of a soluble dye or pigment materials. The fragrant agent preferably includes a phenolic compound. The fragrant ink causes the paper on which it is printed to emit a pleasant scent.

Abstract: A method for creating via holes in a chip or a plurality of chips of a wafer is disclosed. The method is performed by using a pre-patterned transparent mask on the back of the chip or chips, and bombarding the chip(s) through the positioning holes on the transparent mask that correspond to the pre-formed pattern, with accelerated particles. According to this method, via holes can be created from the back of the chip(s) without interfering with the existing IC structure of the chip(s). The present method is highly efficient because a number of via holes can be formed simultaneously by using a large pre-pattered mask to cover the entire wafer. In addition, the present method is cost-effective because no precision apparatus is required.
