    摘要: A method of manufacturing metallic interconnects capable of reducing internal stress inside the metallic layer. The method comprises the steps of forming a silicon-rich oxide layer both before and after the formation of a metallic layer. Therefore, the metallic layer is fully enclosed by silicon-rich oxide layers and any direct contact between the metallic layer and any silicon dioxide layer is avoided. Since the quantity of silicon in the silicon-rich oxide layer is much higher than in a silicon dioxide layer, bonds formed between a silicon atom and an oxygen atom in the silicon-rich oxide layer are much stronger. Consequently, the chance for an aluminum atom in the metallic layer to react with an oxygen atom in the silicon-rich oxide layer is greatly reduced. Hence, lattice vacancies/voids that can lead to conventional stress migration and thermal induced migration problems are prevented.

    摘要: A process for fabricating a mixed signal integrated circuit on a substrate, wherein the substrate is partially covered with a field oxide layer. An oxide layer is formed over a portion of the substrate, wherein the portion of the substrate is not covered with the field oxide layer. First impurities are implanted into the substrate, wherein the first impurities damage the oxide layer. A buffer layer is formed over the oxide layer. A polysilicon layer is formed over the buffer layer. Second impurities are implanted into the polysilicon layer, wherein the buffer layer prevents the oxide layer form being damaged by the second impurities. The polysilicon layer is etched to remove the polysilicon layer, wherein the buffer layer prevents the oxide layer and the substrate from being etched. The portion of buffer layer and the damaged oxide layer over the substrate are removed. The gate oxide layer is formed over the substrate.

    摘要: A method of forming metallic capacitor. The method includes forming a lower electrode for forming the capacitor and a metal conductive line over an inter-layer dielectric such that there are gaps between and on the sides of the lower electrode and the metal conductive line. Thereafter, a first oxide layer is formed that fills the gap, and then a second oxide layer is formed over the inter-layer dielectric. The second oxide layer is later patterned to form a cap oxide layer having an opening that exposes a portion of the lower electrode. Subsequently, a thin dielectric layer is formed over the lower electrode and the cap oxide layer. Finally, an upper electrode is formed over the thin dielectric layer filling the opening.

    摘要: A method of fabricating CMOS image sensor. On a substrate, an isolation layer is formed to partition the substrate into a photodiode sensing region and a transistor element region. Next, on the transistor element region, a gate electrode structure is formed and then, a source/drain region is formed at the transistor element region of the two lateral sides of the gate electrode structure. At the same time, a doping region is formed on the photodiode sensing region. After that, a self-aligned barrier layer is formed on the photodiode sensing region and a protective layer is formed on the substrate. Then, a dielectric layer and a metallic conductive wire are successively formed on the protective layer. Again, a protective layer is formed on the dielectric layer and the metallic conductive wire, wherein the numbers of the dielectric layers and the metallic conductive wire depend on the fabrication process. A protective layer is formed between every dielectric layer.
