Technology for creating a conductive nano-order thin film on the surface of a film in a vacuum is used in applications such as flexible printed circuit boards and transparent conductive films for touch panels.
Sputtering Deposition Technology
Forming layers where interference and scattering of reflected light from the surface of optical films occurs prevents the reflection of outside light and makes displays easier to see.
Reflected light is scattered on the surface by micrometer-scale corrugations which are formed by coating the surface with a resin containing dispersed glass or plastic beads.
Alternating layers with high and low refractive indices and optical thicknesses are designed so that reflected light from the surface and reflected light from optical interfaces cancel each other out.
Sputter Etching Treatment
By supplying high RF voltage to the rotary electrode and inducing a discharge, high energy ions impact a film to form minute undulations and add various functional groups to the surface. Modifying the surface in this way improves adhesion. This technology is used in fluororesin adhesive tape.
By supplying high RF voltage to the lower electrode and inducing a discharge, ions and radicals act on the film surface to add various functional groups to the surface. This technology is employed when forming copper wires on polyimide film.
