    • A method of making vias in a semiconductor IC device having adequate contact to the surface of the interconnects and without inadequate landing is disclosed. The method has interconnects formed in a metal layer on the substrate of the IC device, and a first dielectric layer is formed covering the surface of the interconnects. An etch-stopping layer is then formed on top of the first dielectric layer, followed by the formation of a second dielectric layer on top of the etch-stopping layer. A photoresist layer then covers the second dielectric layer and reveals the surface regions of the second dielectric layer designated for the formation of the vias. A main etching procedure is then performed to etch into the second dielectric layer down to the surface of the etch-stopping layer, thereby forming the first section of the vias. An over-etching procedure is then implemented to strip off the etch-stopping layer and further etches into the first dielectric layer and the etching is then stopped when the surface of the interconnects are revealed to conclude the formation of the vias.

    • A method of manufacturing MOS device including the steps of providing a semiconductor substrate that has a device isolation structure thereon, and then depositing a gate oxide layer, a polysilicon layer and an anti-reflection coating in sequence over the substrate. Next, a gate structure is patterned out of the gate oxide layer, the polysilicon layer and the anti-reflection coating. Then, spacers are formed on the sidewalls of the gate structure. Thereafter, a metal silicide layer is formed over source/drain regions. After that, an inter-layer dielectric (ILD) layer is formed over the gate structure and the entire substrate. Then, the inter-layer dielectric layer is planarized to expose the anti-reflection coating. Next, the anti-reflection coating is removed, and then a barrier layer is deposited over the inter-layer dielectric layer and the polysilicon layer. Subsequently, a conductive layer is deposited over the barrier layer. Finally, a chemical-mechanical polishing operation is carried out to planarize the conductive layer, retaining only the conductive layer above the polysilicon layer.

    • An LDD source/drain region is manufactured adjacent a gate electrode using a single ion implantation step. The method begins by providing a polysilicon gate electrode on a gate oxide over a substrate and then providing a thin, layer of CVD oxide over the gate electrode and over the substrate. A thicker, second layer of a material different from the first silicon oxide layer is deposited over the device and is etched back to form sidewall spacer structures alongside and spaced slightly from the gate electrode. The spacer structures formed from the second layer are then used as a mask to etch the oxide layer where it is exposed over the active regions of the substrate and then the spacer structures are removed. The portion of the oxide layer that remains over the top and sides of the gate electrode and over portions of the substrate adjacent the gate electrode is then used as a mask for an ion implantation process. Implantation through the mask forms a more lightly doped and more shallowly doped region in the substrate beneath the mask and a more heavily doped and more deeply doped region in the portions of the source/drain regions that were not covered by the mask. Accordingly, implantation through the mask formed in this way forms a complete source/drain region having a lightly doped drain structure alongside the FET of the integrated circuit device. Formation of LDD source/drain regions in this manner saves a number of manufacturing steps, resulting in reduced turn around time and reduced costs.
    • 使用单个离子注入步骤在栅极附近制造LDD源极/漏极区域。 该方法开始于在衬底上的栅极氧化物上提供多晶硅栅极电极,然后在栅电极和衬底上方提供薄的CVD氧化物层。 将不同于第一氧化硅层的材料的较厚的第二层沉积在器件上并被回蚀刻以形成旁边并与栅电极稍微间隔开的侧壁间隔结构。 然后将由第二层形成的间隔结构用作掩模以蚀刻其上暴露于衬底的有源区域上的氧化物层,然后去除衬垫结构。 然后,使用保留在栅电极的顶部和侧面以及邻近栅电极的衬底的部分上的氧化物层的部分作为用于离子注入工艺的掩模。 通过掩模的植入在掩模下面的衬底中形成更轻掺杂的并且更浅掺杂的区域,并且在源极/漏极区域的未被掩模覆盖的部分中的更重掺杂和更深的掺杂区域。 因此,通过以这种方式形成的掩模的注入在集成电路器件的FET旁边形成具有轻掺杂漏极结构的完整源/漏区。 以这种方式形成LDD源极/漏极区域节省了许多制造步骤,从而减少了周转时间并降低了成本。

    • The present invention relates to a method of forming lightly doped drains in metallic oxide semiconductor (MOS) components. The method includes forming a first, second, and third insulating layer above a silicon substrate having a gate, etching back the layers to leave behind L-shaped first spacers on sidewalls of the gate, followed by doping second type ions into the silicon substrate to form first lightly doped drains in the silicon substrate surface below the L-shaped first spacers, and second lightly doped drains in the silicon substrate surface elsewhere, further forming a fourth insulating to form third spacers, and using the using the third spacers, the first insulating layer, and the gate as masks when doping second type ions into the silicon substrate so as to form source/drain regions in silicon substrate surfaces not covered by the third spacers. Such a method produces greater yield and reduces leakage current from the transistor components.
