摘要： A shallow trench isolation (STI) structure and methods of forming a STI structure are disclosed. An embodiment is a method for forming a semiconductor structure. The method includes forming a recess in a semiconductor substrate; forming a first material on sidewalls of the recess; forming a widened recessed portion through a bottom surface of the recess; removing the first material from the sidewalls of the recess; and forming a dielectric material in the recess and the widened recessed portion. The bottom surface of the recess is exposed through the first material, and the bottom surface of the recess has a first width. The widened recessed portion has a second width. The second width is greater than the first width.

摘要： A shallow trench isolation (STI) structure has a top portion tapering in width from wide to narrow in a direction from a substrate surface, from a first width at a top of the first portion to a second width at a bottom of the first portion. The STI structure also includes a bottom portion below the top portion, which expands from the bottom of the top portion to a substantially widened lateral distance having a third width. The third width is, in general, substantially larger than the second width. The inventive STI structure can provide desired isolation characteristics with a significantly reduced aspect ratio, thus suitable for device isolations in advanced processing technology.

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.
