    摘要: A method for forming silicide on a semiconductor wafer. The semiconductor wafer includes a doped silicon layer on a predetermined area of the semiconductor wafer, a metal layer positioned on the doped silicon layer, and a barrier layer covering the metal layer. A first rapid thermal processing (RTP) step is performed to make portions of the metal layer react with silicon inside the doped silicon layer so as to form a transitional silicide. The barrier layer and the portions of the metal layer that have not reacted with silicon are then removed. A dielectric layer is formed on the transitional silicide. Finally, a second rapid thermal processing (RTP) step is performed to make the transitional silicide react with portions of the doped silicon layer so as to form the silicide.

    摘要: A novel, moisture-resistant integrated circuit chip package is disclosed. In one embodiment, the integrated circuit chip package includes a rigid substrate having a chip side and a backside. A first conductive layer is formed on the chip side of the substrate, and has a pattern forming conductive traces. A first soldermask layer is formed on the chip side of the substrate. The first soldermask layer directly contacts the first conductive layer. The first soldermask layer has at least one opening formed therein. A first contact layer is formed over the first conductive layer in the opening of the first soldermask layer. A second conductive layer is formed on the backside of the substrate. A second soldermask layer is formed on the back side of the substrate and has at least one opening formed therein. A second contact layer overlies the second conductive layer in the opening of the second soldermask layer. The soldermask layer on the chip side of the substrate has high adhesion to the conductive layer, resulting in a high level of moisture resistance for the package.
