    摘要: A method of fabricating an interconnect for a semiconductor device is disclosed. The method comprises: forming a dielectric layer on a semiconductor substrate; forming a trench in the dielectric layer; placing the semiconductor substrate in a plasma deposition chamber having a tantalum target; initiating a plasma in the presence of nitrogen in the plasma deposition chamber; and depositing an ultra-thin layer comprising tantalum and nitrogen in the trench.

    摘要: A multilevel interconnect structure with a low-k dielectric constant is fabricated in an integrated circuit structure by the steps of depositing a layer of photoresist on a substrate assembly, etching the photoresist to form openings, forming a metal layer on the photoresist layer to fill the openings and then removing the photoresist layer by, for example, ashing. The metal layer is supported by the metal which filled the openings formed in the photoresist.

    摘要: A window-type ball grid array (WBGA) semiconductor package is proposed. A substrate is formed with an opening and a tape attach area around the opening. A polyimide tape having an aperture is applied over the tape attach area, allowing the aperture to be aligned with the opening of the substrate. A chip is mounted over the polyimide tape and electrically connected to the substrate via the opening by bonding wires, wherein the polyimide tape is interposed between the chip and the substrate so as not to leave any gaps between the chip and the substrate. A first encapsulant is formed to fill the opening and encapsulate the bonding wires. A second encapsulant is fabricated to encapsulate the chip. With no gaps between the chip and the substrate, the chip is firmly supported on the substrate during a molding process for fabricating the second encapsulant, thereby preventing chip cracks from occurrence.
