    摘要: The present invention provides a structure and method of forming a butting contact having protective spacers 50A that prevent shorting between a second polysilicon layer 60 and the substrate in a hole 20A in a isolation region 20. The following are provide: a isolation region 20, a first conductive line 30B over portions of the isolation region 20, and an inter-poly insulating layer 40. The protective spacers prevent shorts when the first conductive line 30B is misaligned and exposes a first portion of the isolation region 20 in a butt contact opening. A first photoresist layer 44 having a butt contact photoresist opening 44A over the first doped region 26 and over a first portion of the isolation is formed. The inter-poly insulating layer 40 is etched through the butt contact photoresist opening 44A and etches the first portion of the isolation region forming an isolation hole 20A. In an important step, protective spacers 50A are formed on the sidewalls of the isolation hole 20A. A second conductive layer 60 is formed over an inter-poly insulating layer 40, in the butt contact opening, and over the protective spacers 50A. The protective spacers 50A prevent the second conductive layer 60 from contacting the substrate in the hole 20A.

    摘要: A static random access memory (SRAM) cell includes a straight fin and a bended fin physically disconnected from the straight fin. The bended fin has a first portion and a second portion parallel to the straight fin. The distance between the first portion of the bended fin and the straight fin is smaller than the distance between the second portion of the bended fin and the straight fin. The SRAM cell includes a pull-down transistor including a portion of a first gate strip, which forms a first and a second sub pull-down transistor with the straight fin and the first portion of the bended fin, respectively. The SRAM cell further includes a pass-gate transistor including a portion of a second gate strip, which forms a first sub pass-gate transistor with the straight fin. The pull-down transistor includes more fins than the pass-gate transistor.
