摘要： A continuous length, flexible, polymeric substrate has thin layers of copper clad to opposite sides thereof. Patterns of dry photopolymer material are applied to and mask selected portions of the copper to leave exposed other selected portions of the copper. The copper clad substrate is guided by a series of cathodic electrode rollers exterior of a copper plating bath into successive passes through the bath. Portions of the exposed copper contact the electrode rollers and couple the cathodic potential thereof to the bath to effect the plating of copper from the bath onto the exposed selected portions of the copper.Prior to initial engagement with the cathodic rollers, a series of protrusions are formed in portions of the exposed copper at a height relative to the thickness of the photoresist material sufficient to insure that the copper, by virtue of the protrusions, contacts the electrode rollers to facilitate the plating operation notwithstanding the intervening photoresist material.

摘要： An optical waveguide is made by forming successively of light transmitting material a first clad layer (13), a core layer (15) and a second clad layer (18). The core layer has a higher refractive index than that of the first and second clad layers such that the core layer (15) can transmit light along its length as an optical waveguide. A sacrificial layer (14, 17) is formed surrounding at least a first end potion of the core layer. The sacrificial layer is selectively removed as by selective etching such that the first end portion of the core layer is separated from the first and second clad layers. With the end portion so isolated, a lens (22) can be formed on it such that light may be more effectively coupled to or from the core layer. Preferably, the lens is formed by heating the structure sufficiently to form a meniscus on the free end and then cooling it before the reminder of the core layer flows or melts. The cooling hardens the meniscus such that it constitutes an optical lens.

摘要： A method of removing contaminants from the surface is disclosed. The method comprises coating the surface with a surface active agent having a first surface energy and into which the contaminants are combined, applying thereover a higher surface energy colloidal sol and then allowing sufficient time for the first surface energy material with the contaminants combined therewith to migrate through the colloidal sol so as to remove the contaminants from the immediate vicinity of the substrate surface. The surface may then be treated by exposing it to an acid or base to remove the migrated surfactant layer thus removing the trace of contaminants.

摘要： Prior to the production of microlenses (29) by the reactive ion etch technique, a pattern of notches (25) is formed in a second surface of a substrate (11) opposite a first surface on which the microlenses (29) are to be formed. Reactive ion etching of the first surface to produce the microlenses is sufficiently deep to reach the pattern of notches, thereby to separate the substrate. The array of notches may define, for example, an array of first areas (26) on the second surface, each area being surrounded by a notch. Photoresist elements (28) are then each located on an area of the first surface corresponding to a first area of the second surface, so that the separation separates the substrate into a plurality of segments (26) each containing only one of the microlenses (29). The notches can be made such that each of the segments (26) is cylindrical so that each of the microlenses formed from the substrate has a circular outer periphery.

摘要： A selective metallization process particularly suited for making printed circuit boards comprises the step of treating a substrate having a negative mask thereon with a reactant, e.g., acetic acid, which modifies the surface of the mask without affecting the substrate so as to remove or prevent an active catalytic layer from remaining on the surface of the mask thereby preventing electroless plating on the mask.

摘要： Tapered optical waveguides (33') can be easily made by using photolithographic masking and etching to define on a substrate (21) a first polymer structure (22) having a substantially uniform thickness and a tapered width. The first polymer structure is heated sufficiently to form a meniscus along its entire length. The fluidity causes the material to redistribute itself such that, rather than being of uniform thickness, it has a thickness that varies with its width; consequently, the thickness as well as the width of the first polymer structure becomes tapered. The first polymer is cooled and hardened to form a second polymer structure (22') that has a tapered width and a tapered thickness as is desirable for a tapered optical waveguide. The second polymer structure itself can be used as a tapered optical waveguide, or it can be used to control the reactive ion etching of the underlying substrate. In the latter case, the configuration of the tapered second polymer structure is replicated in a glass substrate, for example, which then may be used as a glass tapered optical waveguide (33').
摘要翻译：锥形光波导（33'）可以通过使用光刻掩模和蚀刻来在衬底（21）上限定具有基本上均匀的厚度和锥形宽度的第一聚合物结构（22）来容易地制成。第一聚合物结构被充分加热以在整个长度上形成弯液面。流动性导致材料重新分布自身，使得不是具有均匀的厚度，而是具有随其宽度而变化的厚度; 因此，第一聚合物结构的厚度以及宽度变得逐渐变细。将第一聚合物冷却并硬化以形成第二聚合物结构（22'），其具有如锥形光波导所需的锥形宽度和锥形厚度。第二聚合物结构本身可以用作锥形光波导，或者可以用于控制底层基板的反应离子蚀刻。在后一种情况下，锥形第二聚合物结构的构造被复制在例如可用作玻璃锥形光波导（33'）的玻璃基板中。
