    • A method is provided for fabricating a dual damascene structure on a substrate with a first dielectric layer, an etching stop layer, a second dielectric layer, and a hard mask layer formed on it. The first step is to define the hard mask layer in order to form the first hole, which corresponds to the position of the conductive layer exposing the second dielectric layer. Then, an etching process, including an etching step with medium SiO.sub.2 /SiN etching selectivity and an over-etching step with high SiO.sub.2 /SiN etching selectivity, is performed to form the second hole and the third hole. Finally, a glue/barrier layer and a metal layer are filled into the second hole and the third hole, thus accomplishing a dual damascene structure.

    • A method of forming a DRAM includes forming a transfer FET on a substrate, the FET having a gate on a gate oxide layer above the substrate and a first and second source/drain region in the substrate on either side of a channel region under the gate. The first and second source/drain regions are typically exposed or nearly exposed in a spacer etch process. A silicon nitride etch stop layer is deposited over the entire structure and then a thick layer of oxide is deposited on the device. Chemical mechanical polishing is performed to provide a planar surface on the thick oxide layer. An opening is formed through the thick layer of oxide above the first source/drain region, stopping at the etch stop layer. The etch stop layer is removed within the opening in the thick layer of oxide and the underlying thin oxide layer is etched. A capacitor electrode can then be formed in contact with the exposed portion of the first source/drain region. A similar self-aligned method can be used to form the bit line contact for the device using the etch stop layer as a stop for the bit line contact etch. Practice of the method provides a manufacturing method having improved reliability and ease of use, particularly when practiced for DRAM capacitors that incorporate high dielectric constant dielectrics. The materials preferred for use within such DRAM capacitors have smaller process margins and so particularly benefit from the improved structure and process.
    • 形成DRAM的方法包括在衬底上形成转移FET,所述FET在衬底上方的栅极氧化物层上具有栅极,并且在栅极之下的沟道区域的任一侧上的衬底中的第一和第二源极/漏极区域 。 第一和第二源极/漏极区域通常在间隔物蚀刻工艺中暴露或接近露出。 在整个结构上沉积氮化硅蚀刻停止层,然后在器件上沉积厚层氧化物。 进行化学机械抛光以在厚氧化物层上提供平坦表面。 在第一源极/漏极区域上方的厚的氧化物层形成开口,在蚀刻停止层处停止。 蚀刻停止层在氧化物的厚层的开口内去除,并且下面的薄氧化物层被蚀刻。 然后可以形成与第一源极/漏极区域的暴露部分接触的电容器电极。 可以使用类似的自对准方法来形成使用蚀刻停止层作为位线接触蚀刻停止的器件的位线接触。 该方法的实践提供了具有改进的可靠性和易用性的制造方法,特别是当实施用于包含高介电常数电介质的DRAM电容器时。 优选用于这种DRAM电容器的材料具有较小的工艺裕度,因此特别受益于改进的结构和工艺。

    • A full-spectrum absorption solar cell adopts cobalt-doped tin dioxide as an N-type material. Thereby, a solar cell of the present invention can be fabricated by a spray method in a hot pressing fabrication process. The present invention does not need to fabricate a solar cell in a vacuum or furnace system and thus can solve the high cost problem of the conventional technology. The N-type cobalt-doped layer can absorb full spectrum of sunlight. The N-type cobalt-doped layer can be used to fabricate a solar cell with a low-temperature fabrication process. Thus, the present invention does not need to adopt a high-temperature resistant substrate (such as silicon chip or glass) used in the conventional high-temperature fabrication process but can adopt a substrate made of plastic. And, the conversion efficiency of the invention can achieve 1.2%, it is a significant improvement over the oxide-based nanostructures heterojunction solar cells in the world.

    • A method for fabricating interconnections with carbon nanotubes of the present invention comprises the following steps: forming a dual-layer that contains a catalytic layer and an upper covering layer on the periphery of a hole connecting with a substrate; and growing carbon nanotubes on the catalytic layer with the upper covering layer covering the carbon nanotubes. The present invention grows the carbon nanotubes between the catalytic layer and the upper covering layer. The upper covering layer protects the catalytic layer from being oxidized and thus enhances the growth of the carbon nanotubes. The carbon nanotubes are respectively connected with the lower substrate and an upper conductive wire via the catalytic layer and the upper covering layer, which results in a lower contact resistance. Moreover, the upper covering layer also functions as a metal-diffusion barrier layer to prevent metal from spreading to other materials via diffusion or other approaches.
