The remainder of the circuit line surfaces are smooth. Thus, those areas for propagation of the signal on signal lines have the circuit lines smooth to maximize the signal propagation effect, while those areas where the signal propagation is not critical are rough, which improves the adhesion of one layer to another. On the voltage planes, the surface in those regions opposite the smooth surfaces of the signal planes is smooth. Thus, these areas of the voltage planes can be maintained smooth while the other areas of the surface of the voltage planes can be roughened, providing good adhesion to the adjoining dielectric material.

    Abstract: A method of improving the ability of plastic layers of a multi-layered optical disc to bond to adhesive materials includes exposing the plastic layers to a plurality of ions. In one embodiment, one side of a plastic layer of a multi-layered optical disc is exposed to a plurality of non-reactive ions, an adhesive material is applied to the side of the plastic layer that was exposed to the plurality of ions, and a second layer of the optical disc is secured to the adhesive material. In another embodiment, a plurality of ions is formed by directing gas molecules through an electric field, and at least 25% of the width of the plastic layer of the multi-layered optical disc is exposed to the plurality of ions at about the same time. The plastic layer is positioned so that the ions contact the plastic layer while the ions still have a charge, and the disc is moved so that at least 25% of the surface of the plastic layer is exposed to the plurality of ions.

  • Patent number: 6668445
    Abstract: A method of tape automated bonding a heater chip of an ink jet printer to a flexible circuit includes the step of attaching an electrically conductive bonding pad to a first portion of a surface of the heater chip. A mask is applied to a second portion of the surface of the heater chip. An exposed surface of the bonding pad is chemical dry etched for a predetermined time period to thereby remove contaminants from the etched exposed surface. The chemical dry etching is terminated at an end of the predetermined time period such that substantially none of the bonding pad is removed. Lastly, the flexible circuit is electrically connected to the etched exposed surface.

  • Patent number: 6506499
    Abstract: A surface treatment, especially for titanium and aluminum alloys, forms a Si—Y sol-gel film covalently bonded on the metal surface to produce strong, durable adhesive bonds between the metal and an organic adhesive without using toxic chemicals and while significantly reducing or eliminating rinse water requirements of traditional anodizing or etching processes. The sol should produce bonds in a single application comparable in strength and performance to standard anodize controls. Parameters affecting performance include the sol composition, the ratio of silicon to yttrium in the sol, the ratio of other sol ingredients, the concentration of the sol, the carrier solvent, solution age, catalysts, surface pretreatment, application method, curing process, and primer used.

  • Patent number: 6500349
    Abstract: A continuous process for forming multilayer circuit structures which includes applying and curing a film forming polymer onto the matte side of a copper foil. The opposite (shiny) side of the foil is optionally but preferably cleaned, and applied with a photoresist which is then optionally but preferably dried. The photoresist is exposed, and developed to remove the nonimage areas but leave the image areas. The foil under the removed nonimage area is then etched to form a copper pattern, and the remaining photoresist is optionally but preferably removed. The foil is then cut into sections, and then optionally but preferably punched with registration holes. The copper pattern is then optionally but preferably treated with a bond enhancing treatment, optionally but preferably inspected for defects, and laminated onto a substrate to form a multilayered circuit structure.

  • Publication number: 20020148810
    Abstract: A surface treatment method for thinning a silicon based substrate obtains a milky-dull color on an overall surface uniformly of the silicon based substrate. To be more specific, a surface opposite to a circuit-formed surface is mechanically polished, then the surface is etched using inert gas such as argon gas for producing plasma. This etching forms micro dimples uniformly on the surface. Next, the surface is further etched using fluorine based gas for producing plasma. This etching obtains a milky-dull color uniformly on the surface. As a result, printed marks on the surface can be read with ease, and pick-up errors in die-bonding can be reduced.
