Abstract: A mechanism and a method for framing a low-distortion flexible dielectric substrate during subsequent flex circuit processing. The processing method comprising the following steps: making a flexible dielectric substrate having an outer periphery; joining a continuous portion of the flexible dielectric substrate near the outer periphery to a rigid open frame, the flexible dielectric substrate being in a state other than a state of substantially uniform tension as a result of the joinder; causing the joined flexible dielectric substrate to undergo a change to the state of substantially uniform tension; and printing an electrical conductor on the flexible dielectric substrate while the flexible dielectric substrate is joined to the frame and in the state of substantially uniform tension. The frame is in the shape of a polygon (e.g., a rectangle) with rounded vertices.

Abstract: An optoelectronic package is fabricated by a method which includes: positioning an optical device within a window of a substrate active-side up and below a top substrate surface; filling the window with an optical polymer material; planarizing surfaces of the optical polymer material and the substrate; patterning waveguide material over the optical polymer material and the substrate to form an optical interconnection path; and to form a mirror to reflect light from the optical device to the interconnection path; and forming a via to expose a bond pad of the optical device.

Abstract: A method and process sequence for accurately aligning (die to interconnect metal on flex substrate such as polyimide flex is described. A mask for via formation is first patterned in a metal layer on the bottom surface of the flex substrate. Die attach means such as die attach adhesive is then applied to the top side of flex substrate. The bond pads on die are locally, adaptively aligned to the patterned metal via mask on the flex with high accuracy. Vias down to the die bond pads are then created by either plasma etching or excimer laser ablation through the existing aligned metal mask on the flex substrate, and interconnect metal is then deposited, patterned and etched. As a result of this process, the flex metal interconnect artwork does not have to be customized for each die misplacement using “adaptive lithography”. Lower cost commercially available lithography equipment can be used for processing, reducing capital equipment and processing cost.

Abstract: A hard layer of amorphous hydrogenated carbon (DLC) overlies a polymer film structure and a plurality of soft layers of DLC alternate with a plurality of hard layers of DLC over the barrier base to form a corrosion resistant structure. The polymer film structure and a circuit chip can be elements of a circuit module. The DLC and the polymer film structure can have vias extending to contact pads, and a pattern of electrical conductors can extend through the vias to the contact pads. In one embodiment the DLC forms a hermetic (and therefore corrosion resistant) seal over the polymer film structure.
