  • Patent number: 10770459
    Abstract: A silicon oxide liner, a silicon nitride liner, and a planarization silicon oxide layer may be sequentially formed over p-type and n-type field effect transistors. A patterned dielectric material layer covers an entirety of the n-type field effect transistor and does not cover at least a fraction of each area of p-doped active regions. An anisotropic etch process is performed to form p-type active region via cavities extending to a respective top surface of the p-doped active regions and n-type active region via cavities having a respective bottom surface at, or within, one of the silicon nitride liner and the silicon oxide liner. Boron-doped epitaxial pillar structures may be formed on top surfaces of the p-type active regions employing a selective epitaxy process. The n-type active region via cavities are extended to top surfaces of the n-doped active regions. Contact via structures are formed in the via cavities.

  • Patent number: 9755012
    Abstract: In connection with a semiconductor device including a capacitor element there is provided a technique capable of improving the reliability of the capacitor element. A capacitor element is formed in an element isolation region formed over a semiconductor substrate. The capacitor element includes a lower electrode and an upper electrode formed over the lower electrode through a capacitor insulating film. Basically, the lower electrode and the upper electrode are formed from polysilicon films and a cobalt silicide film formed over the surfaces of the polysilicon films. End portions of the cobalt silicide film formed over the upper electrode are spaced apart a distance from end portions of the upper electrode. Besides, end portions of the cobalt silicide film formed over the lower electrode are spaced apart a distance from boundaries between the upper electrode and the lower electrode.
