    摘要: A method of forming a suicide layer is described. A silicon layer is provided. Ions are introduced in the silicon layer. A metal layer is formed on the silicon layer. An annealing process is performed so that the silicon layer reacts with the metal layer to form the metal silicide layer. Thereafter, the unreacted metal layer is removed. The uniformity of the grain size and the grain distribution of the metal silicide layer are improved by introducing the ions in the silicon layer before performing the annealing process, so that sheet resistance of the metal silicide layer is reduced.

    摘要: A chemical mechanical polishing to polish a substrate having a layer to be polished thereon is described. A pre-polishing process is performed using a softer polishing pad to remove partially raised parts of the layer to be polished before conducting a polishing process using a harder polishing pad. Since the first polishing pad is flexible, porous and with low density, the first polishing pad can be deformed to increase contact areas between the first polishing pad and the raised part of the layer to be polished, and the abrasives are embedded easily in holes of the surface of the first polishing pad. Ultimately, the layer to be polished can be polished directly during the pre-polishing process. Therefore, the processing time is reduced, the consumption of the slurry is decreased and the process cost can be cut down substantially.

    摘要翻译: 描述了对具有待抛光层的基板进行化学机械抛光。 在使用更硬的抛光垫进行抛光处理之前,使用较软的抛光垫进行预抛光工艺以去除待抛光层的部分凸起部分。 由于第一抛光垫是柔性的,多孔的并且具有低密度,所以第一抛光垫可以变形以增加第一抛光垫与被抛光层的凸起部分之间的接触面积,并且磨料易于嵌入到 第一抛光垫的表面。 最终,抛光过程中可以直接抛光抛光层。 因此,处理时间缩短,浆料的消耗量减少,工序成本大幅降低。

    摘要: A method of fabricating a flash memory device is provided. First, a substrate partitioned into a memory cell region and a peripheral circuit region is provided. A tunnel dielectric layer is formed over the memory cell region and a liner layer is formed over the peripheral circuit region. Thereafter, a patterned gate conductive layer is formed over the substrate. An inter-gate dielectric layer and a passivation layer are sequentially formed over the substrate. The passivation layer, the inter-gate dielectric layer, the gate conductive layer and the liner layer over the peripheral circuit region are removed. A gate dielectric layer is formed over the peripheral circuit region while the passivation layer over the memory cell region is converted into an oxide layer. Another conductive layer is formed over the substrate. The conductive layer, the oxide layer, the inter-gate dielectric layer and the gate conductive layer over the memory cell region are patterned to form a memory gate. The second conductive layer over the peripheral circuit region is similarly patterned to form a gate.

    摘要: A fabrication method for a shallow trench isolation region is described. A part of the trench is filled with a first insulation layer, followed by performing a surface treatment process to form a surface treated layer on the surface of a part of the first insulation layer. The surface treated layer is then removed, followed by forming a second insulation layer on the first insulation layer and filling the trench to form a shallow trench isolation region. Since a part of the trench is first filled with the first insulation layer, followed by removing a portion of the first insulation layer, the aspect ratio of the trench is lower before the filling of the second insulation in the trench. The adverse result, such as, void formation in the shallow trench isolation region due to a high aspect ratio, is thus prevented.

    摘要: A system and method for modifying an integrated circuit (IC) layout includes performing a correction process, such as an optical proximity correction (OPC) process, only on regions within designated blocks that are defined around respective modified structures. An IC layout can be compared to a modified version of the IC layout to detect modified structures. One or more large blocks can then be defined around respective modified structures. A correction process can then be performed on only the one or more large blocks. Small blocks within respective large blocks can then be extracted from the modified IC layout and merged with the original IC layout to generate a final modified and corrected IC layout.
