    摘要: The present invention is a mask and methods for making masks for use with a laser projection etching system. The unique mask is able to withstand the fluences of the high energy and high power lasers used without degrading. Specifically, the new projection etching masks are fabricated of patterned multiple dielectric layers having alternating high and low indices of refraction on a UV grade synthetic fused silica substrate in order to achieve maximum reflectivity of the laser energy in the opague areas and maximum transmissivity of the laser energy in the transparent areas of the mask.

    摘要: A system and method for injection molding conductive bonding material into a plurality of cavities in a non-rectangular mold is disclosed. The method comprises aligning a fill head with a non-rectangular mold. The non-rectangular mold includes a plurality of cavities. The fill head is placed in substantial contact with the non-rectangular mold. Rotational motion is provided to at least one of the non-rectangular mold and the fill head while the fill head is in substantial contact with the non-rectangular mold. Conductive bonding material is forced out of the fill head toward the non-rectangular mold. The conductive bonding material is provided into at least one cavity of the plurality of cavities contemporaneous with the at least one cavity being in proximity to the fill head.

    摘要: A method of fabricating a high resolution ablation mask for use at laser fluences of greater than 200 mJ/cm.sup.2 is disclosed. The method comprises combining dry etching and chemical etching of an unetched ablation mask which comprises a transparent substrate, a layer of high UV light refractivity material, e.g. aluminum, deposited on said substrate, and a photoresist layer positioned on a predetermined area of said high UV light refractivity material layer leaving other areas of said high UV light refractivity material layer exposed.
