    摘要: The present invention discloses a method for simultaneously manufacturing a poly gate and a polycide gate which requires only one gate oxide layer deposition and one polysilicon layer deposition steps by incorporating a protective layer, primarily an oxide layer, which acts as a mask of a silicide. The present invention not only simplifies the process but also avoids a residual spacer in the gate. The advantages also includes widening the process window, controlling the gate channel and avoiding the gate top loss.

    摘要: A process for fabricating stacked capacitor, DRAM, devices, has been developed in which the surface area of the storage node has been significantly increased as a result of a unique set of deposition and annealing conditions. An amorphous polysilicon layer, used as the upper layer of the storage node, is ramped up in pure nitrogen, and then insitu annealed, to result in a polycrystalline structure, exhibiting significant surface area increases, due to the formation of surface concave and convex protrusions. The increase in storage node surface area allows for increased DRAM capacitance, without the use of larger dimension stacked capacitors, or thinner dielectrics.

    摘要: A fabrication method for a semiconductor device. On a semiconductor silicon substrate with a first type conductivity, an epitaxial layer with a second type conductivity and an oxide layer on the epitaxial layer are formed with at least a deep trench. Ion implantation is used to form an ion diffusion region with the first type conductivity which is formed in the epitaxial layer and surrounds the sidewall and bottom of the deep trench. An oxide liner is formed on the sidewall and bottom of the deep trench, and then an undoped polysilicon layer is formed to fill the deep trench. The combination of the ion diffusion region and the undoped polysilicon layer serves as a deep trench isolation structure.
