    • A method of fabricating a flash memory includes successive formation of a first polysilicon layer, a first dielectric layer and a hard material layer on a substrate with a tunnelling oxide layer. Then the hard material layer, the first dielectric layer and the first polysilicon layer are defined and the first polysilicon layer serves as a floating gate of the flash memory. After the step of definition, a source/drain region is formed on the substrate on the sides of the floating gate and an insulating spacer is also formed thereon. An inter-poly dielectric layer is then formed over the substrate and CMP is performed to etch back the inter-poly dielectric layer, exposing the surface of the hard material layer serving as a stop layer. Next, the hard material layer is removed and the first polysilicon layer is doped with impurities. A second dielectric layer is formed over the substrate and covers the surface of the first polysilicon layer. Subsequently, the second polysilicon layer is formed and defined to serve as a control gate of the flash memory.

    • A method for manufacturing SRAM loads comprising the steps of sequentially forming a silicon oxide layer and a silicon nitride layer over a polysilicon layer. Then, the silicon oxide layer and the silicon nitride layer are patterned to form vias exposing a load region. Thereafter, using a thermal oxidation operation, an oxide layer is formed above the load region. Subsequently, the silicon nitride layer and the silicon oxide layer are removed. Through the formation of an oxide layer over the load region, the cross-sectional thickness and width of the load are reduced, thereby moderating the out-diffusion of ions while maintaining the load resistance. Furthermore, the oxide layer, which forms over the load region in the back-end process, can serve as a barrier layer preventing the out-diffusion of ions and blocking incoming moisture.
    • 一种用于制造SRAM负载的方法,包括以下步骤:在多晶硅层上依次形成氧化硅层和氮化硅层。 然后,将氧化硅层和氮化硅层图案化以形成暴露负载区域的通孔。 此后,使用热氧化操作,在负载区域的上方形成氧化物层。 随后,去除氮化硅层和氧化硅层。 通过在负载区域上形成氧化物层,减小了负载的横截面厚度和宽度,从而缓和了离子的扩散,同时保持了负载电阻。 此外,在后端工艺中在负载区域上形成的氧化物层可以用作防止离子的扩散和阻止进入的水分的阻挡层。
