    摘要: A high-voltage semiconductor MOS process that is fully compatible with low-voltage MOS process is provided. The high-voltage N/P well are implanted into the substrate prior to the definition of active areas. The channel stop doping regions are formed after the formation of field oxide layers, thus avoiding lateral diffusion of the channel stop doping regions. In addition, the grade drive-in process used to activate the grade doping regions in the high-voltage device area and the gate oxide growth of the high-voltage devices are performed simultaneously.

    摘要: A method of fabricating an interconnect is described in which a conductive layer, an anti-reflection layer and a cover layer are sequentially formed on the substrate to form a conductive plug with its bottom situated in the anti-reflection layer. The cover layer and a portion of the anti-reflection layer and the conductive layer are remove to form an opening exposing the substrate and to define the conductive lining structures. A conformal polysilicon oxide layer is formed on the substrate and a first dielectric layer is also formed, filling the opening. A conformal isolation layer is then formed on the substrate, followed by forming a second dielectric layer covering the entire substrate. A planarization procedure is further conducted to expose the conductive plug.

A dielectric layer with a relatively low dielectric constant is formed over the substrate. A patterned photoresist layer is formed on the dielectric layer. The patterned photoresist layer has an opening exposing a portion of the dielectric layer. The portion of the dielectric layer exposed by the opening is removed to form a via hole. The patterned photoresist layer is removed by an O.sub.2 --H.sub.2 O--CF.sub.4 plasma. The pressure of the O.sub.2 --H.sub.2 O--CF.sub.4 plasma is about 800-1000 torr. A cleaning process is performed by a post-stripper rinse solution and de-ionized water without using an acetone solution. A barrier layer is formed over the substrate by chemical vapor deposition. A metal nucleation is performed for a long time by chemical vapor deposition to form metal nuclei on the barrier layer. A metal layer is formed to fill the via hole by chemical vapor deposition.
