摘要： Disclosed are embodiments of a trigate field effect transistor that comprises a fin-shaped semiconductor body with a channel region and source/drain regions on either side of the channel region. Thick gate dielectric layers separate the top surface and opposing sidewalls of the channel region from the gate conductor in order to suppress conductivity in the channel planes. A thin gate dielectric layer separates the upper corners of the channel region from the gate conductor in order to optimize conductivity in the channel corners. To further emphasize the current flow in the channel corners, the source/drain regions can be formed in the upper corners of the semiconductor body alone. Alternatively, source/drain extension regions can be formed only in the upper corners of the semiconductor body adjacent to the gate conductor and deep source/drain diffusion regions can be formed in the ends of the semiconductor body.

摘要： Disclosed are embodiments of a structure that comprises a first device, having multiple FETs, and a second device, having at least one FET. Sections of a first portion of a semiconductor layer below the first device are doped and contacted to form back gates. A second portion of the semiconductor layer below the second device remains un-doped and un-contacted and, thus, functions as an insulator. Despite the performance degradation of the first device due to back gate capacitance, the back gates result in a net gain for devices such as, SRAM cells, which require precise Vt control. Contrarily, despite marginal Vt control in the second device due to the absence of back gates, the lack of capacitance loading and the added insulation result in a net gain for high performance devices such as, logic circuits.
摘要翻译：公开了包括具有多个FET的第一器件和具有至少一个FET的第二器件的结构的实施例。第一器件下方的半导体层的第一部分的部分被掺杂并接触以形成后栅极。第二器件下方的半导体层的第二部分保持未掺杂和未接触，并因此用作绝缘体。尽管由于背栅电容而导致第一器件的性能下降，但是后栅导致需要精确Vt控制的诸如SRAM单元的器件的净增益。相反，尽管由于不存在后门而导致第二器件中的边缘Vt控制，但由于缺少电容负载和增加的绝缘，导致高性能器件（如逻辑电路）的净增益。

摘要： Disclosed are planar and non-planar field effect transistor (FET) structures and methods of forming the structures. The structures comprise segmented active devices (e.g., multiple semiconductor fins for a non-planar transistor or multiple semiconductor layer sections for a planar transistor) connected at opposite ends to source/drain bridges. A gate electrode is patterned on the segmented active devices between the source/drain bridges such that it has a reduced length between the segments (i.e., between the semiconductor fins or sections). Source/drain contacts land on the source/drain bridges such that they are opposite only those portions of the gate electrode with the reduced gate length. These FET structures can be configured to simultaneously maximize the density of the transistor, minimize leakage power and maintain the parasitic capacitance between the source/drain contacts and the gate conductor below a preset level, depending upon the performance and density requirements.
摘要翻译：公开了平面和非平面场效应晶体管（FET）结构和形成结构的方法。这些结构包括在源极/漏极桥两端连接的分段有源器件（例如，用于非平面晶体管的多个半导体鳍片或用于平面晶体管的多个半导体层部分）。在源极/漏极桥之间的分段有源器件上图案化栅电极，使得栅极电极在段之间（即，半导体鳍片或部分之间）具有减小的长度。源极/漏极接触器接地在源/漏极桥上，使得它们仅与具有减小的栅极长度的栅电极的那些部分相对。这些FET结构可以被配置为同时使晶体管的密度最大化，从而使漏极功率最小化，并且将源极/漏极触点和栅极导体之间的寄生电容保持在预定值以下，这取决于性能和密度要求。

摘要： Disclosed is a semiconductor structure and associated method of performing the structure with good performance and stability trade-offs for digital circuits and SRAM cells and/or analog FETs on the same chip. Specifically, a dual-strain layer is formed over digital circuits and the other devices on a chip. The dual-strain layer comprises tensile sections above digital logic n-type transistors, compressive sections above digital logic p-type transistors and additional tensile sections above SRAM cells and/or analog FETs. An amorphization ion-implant is performed to relax the strain over SRAM cell p-FETs and, thereby, eliminate variability and avoid p-FET performance degradation in the SRAM cells. Additionally, this ion-implant can relax the strain above both analog p-FETs and n-FETs and, thereby, eliminate variability and the coupling of the logic device process to the analog FETs and provide more predictable and well-controlled analog FETs.

摘要： An integrated circuit structure has a buried oxide (BOX) layer above a substrate, and a first-type fin-type field effect transistor (FinFET) and a second-type FinFET above the BOX layer. The second region of the BOX layer includes a seed opening to the substrate. The top of the first-type FinFET and the second-type FinFET are planar with each other. A first region of the BOX layer below the first FinFET fin is thicker above the substrate when compared to a second region of the BOX layer below the second FinFET fin. Also, the second FinFET fin is taller than the first FinFET fin. The height difference between the first fin and the second fin permits the first-type FinFET to have the same drive strength as the second-type FinFET.

摘要： Disclosed is a multiple-gate transistor that includes a channel region and source and drain regions at ends of the channel region. A gate oxide is positioned between a logic gate and the channel region and a first insulator is formed between a floating gate and the channel region. The first insulator is thicker than the gate oxide. The floating gate is electrically insulated from other structures. Also, a second insulator is positioned between a programming gate and the floating gate. Voltage in the logic gate causes the transistor to switch on and off, while stored charge in the floating gate adjusts the threshold voltage of the transistor. The transistor can comprise a fin-type field effect transistor (FinFET), where the channel region comprises the middle portion of a fin structure and the source and drain regions comprise end portions of the fin structure.
