Process for transferring a coating onto a surface of a lens blank
InactiveUS7455796B2Risk of deformationAvoid distortionLamination ancillary operationsLaminationEngineeringOptical surface
A process for transferring a coating onto at least one optical surface of a lens blank which comprises:providing a lens blank having at least one geometrically defined surface;providing a support having an internal surface bearing a coating and an external surface;depositing on said geometrically defined surface of said lens blank or said coating a pre-measured amount of a curable glue;moving relatively to each other the lens blank and the support to either bring the coating into contact with the curable glue or bring the curable glue into contact with the geometrically defined surface of the lens blank;applying a sufficient pressure onto the external surface of the support so that the thickness of a final glue layer after curing is less than 100 micrometers;curing the glue; andwithdrawing the mold part to recover the lens blank with the coating adhered onto its geometrically defined surface.

There is provided a semiconductor device in which substantially no deformation of a bonded wire occurs, and a method for producing the semiconductor device. A wiring pattern of a wiring substrate and an electrode of an IC chip are connected by a wire. A contact prevention resin whose height is higher than the highest position of the bonded wire, is adhered to the approximate center of the surface of the IC chip. If the wiring substrate warps due to heat from the lower metallic mold, an inner surface of an upper metallic mold placed on the wiring substrate abuts against the contact prevention resin, and decrease warpage of the wiring substrate. Accordingly, the wire is kept from contacting the inner surface of the upper metallic mold. Thereafter, the IC chips, the wires, and the like are sealed by injecting a mold resin into the molds.
