    摘要: An FET device and method of making comprising a first dielectric layer; a substrate layer on the dielectric layer; a channel region of a first conductivity type formed in the substrate layer; a gate formed above the substrate layer over the channel region; FET diffusion regions of a second conductivity type formed in the substrate layer, the diffusion regions each having edges, the edges of the FET diffusion regions being separated by the channel region; and a body contact region of the first conductivity type extending continuously from the channel region. The first conductivity type material in the body contact region is thinner than the first conductivity type material in the channel region. The FET also includes a second dielectric layer formed on the body contact region.

    摘要: A method of forming a semiconductor device. A first dielectric layer is deposited on and in direct mechanical contact with the substrate. A first hard mask is deposited on the first dielectric layer. A first and second trench is formed within the first dielectric layer and the first hard mask. The second trench is wider than the first trench. A first conformal liner is deposited over the first hard mask and within the first and second trenches, a portion of which is removed, leaving a remaining portion of the first conformal liner in direct physical contact with the substrate, the first dielectric layer, and the first hard mask, and not on the first hard mask. Copper is deposited over the first conformal liner to overfill fill the first and second trenches and is planarized to remove an excess thereof to form a planar surface of the copper.

    摘要: In order to reduce power dissipation requirements, obtain full potential transistor performance and avoid power dissipation limitations on transistor performance in high density integrated circuits, transistors are operated in a sub-threshold (sub-Vth) or a near sub-Vth voltage regime (generally about 0.2 volts rather than a super-Vth regime of about 1.2 volts or higher) and optimized for such operation, particularly through simplification of the transistor structure, since intrinsic channel resistance is dominant in sub-Vth operating voltage regimes. Such simplifications include an underlap or recess of the source and drain regions from the gate which avoids overlap capacitance to partially recover loss of switching speed otherwise caused by low voltage operation, an ultra-thin gate structure having a thickness of 500 Å or less which also simplifies forming connections to the transistor and an avoidance of silicidation or alloy formation in the source, drain and/or gate of transistors.
