Abstract: An optical semiconductor package includes a substrate, a chip, a plurality of bonding wires, a window, a supporter, and an encapsulant. The chip is disposed on the substrate and has an optical element. The bonding wires are used for electrically connecting the chip to the substrate. The window is supported on the supporter and positioned over the optical element of the chip. The encapsulant is overmolded on the substrate for fixing the window and encapsulating the chip and the bonding wires.

Abstract: A method for manufacturing an adhesive substrate with a die-cavity sidewall is disclosed. A region for forming die-cavity sidewall is defined on one surface of the substrate. The substrate is laminated with a sacrificial film, a partially cured resin is formed between the substrate and the sacrificial film. And then, an aperture is routed through the substrate, the partially cured resin, and the sacrificial film. The aperture is located corresponding to the region so that the substrate has a die-cavity sidewall formed inside the aperture. Thereafter, the sacrificial film is removed to expose the partially cured resin on the substrate so that the substrate with a die-cavity sidewall can have good adhesion.

Abstract: A method for manufacturing a semiconductor package with a laminated chip cavity is disclosed. A board and a metal foil having a layer of adhesive resin are provided. The metal foil is laminated with the board to make the adhesive resin be attached to the board. Next, a through opening is formed to pass through the board, the adhesive resin and the metal foil. Next, the metal foil is removed to expose an adhesive surface of the adhesive resin on the board so as to attach a carrier plate, thereby forming a chip cavity.

Abstract: A method of forming a plurality of solid conductive bumps for interconnecting two conductive layers of a circuit board with substantially coplanar upper surfaces. The method comprises the steps of applying a continuous homogenous metal layer onto a dielectric substrate, applying a first photoresist and exposing and developing said first photoresist to define a pattern of conductive bumps, etching the metal layer exposed by said development to form said plurality of conductive bumps, removing said first photoresist, applying a second photoresist onto the metal layer, exposing and developing said second photoresist to define a pattern of conductive bumps and circuit lines; etching the metal layer exposed by said development to form a pattern of circuit lines in said metal layer; and removing said second photoresist. The methods of the present invention also provides for fabricating a multilayer circuit board and a metallic border for providing rigidity to a panel.
