    摘要: According to an embodiment of the invention, an integrated circuit (IC) package is provided that includes a flexible circuit board that has a first surface and a second surface. An integrated circuit mounted to the first surface of the flexible circuit board is provided. An electrical element is attached to the second surface of the flexible circuit board. Also, an encapsulant is attached to the flexible circuit board and the integrated circuit. The flexible circuit board includes at least one layer of dielectric that is no greater than approximately 35 microns thick. In another embodiment, the integrated circuit and the electrical element may be interchanged. A method is provided including attaching an encapsulant to an IC, forming a substrate from at least one layer of dielectric, attaching at least one electrical contact to the substrate, and attaching the substrate to the encapsulant so that the substrate is connected to the IC. Also, an electrical element may be attached with a flip-chip C4 (controlled collapsed chip connection) process.

    摘要: An etchback process for etching a refractory metal layer formed on a semiconductor substrate with a greatly reduced micro-loading effect. The etch proceeds in three steps. The first step is a uniform etch which utilizes a gas chemistry of SF.sub.6, O.sub.2 and He and proceeds for a predetermined time to remove most of the metal layer. The second step is a very uniform etch which utilizes a gas chemistry of SF.sub.6, Cl.sub.2 and He and proceeds until the endpoint is detected. The endpoint is detected by measurement and integration of the 772 nm and 775 nm lines of Cl. The third step is a timed etch utilizing a gas chemistry of Cl.sub.2 and He which is used as both an overetch to ensure complete removal of the refractory metal film and as a selective etchant to remove an adhesion underlayer.
