    摘要: Optimal strain in the channel region of a PMOS transistor is provided by silicon alloy material in the junction regions of the device in a non-planar relationship with the surface of the substrate. The silicon alloy material, the dimensions of the silicon alloy material, as well as the non-planar relationship of the silicon alloy material with the surface of the substrate are selected so that the difference between the lattice spacing of the silicon alloy material and of the substrate causes strains in the silicon alloy material below the substrate surface, as well as above the substrate surface, to affect an optimal silicon alloy induced strain in the substrate channel. In addition, the non-planar relationship may be selected so that any strains caused by different lattice spaced layers formed over the silicon alloy material have a reduced effect on the strain in the channel region.

    摘要: A method and an apparatus for forming a transistor suitable for a high voltage circuit. In one embodiment, the transistor is formed without adding any steps to an existing state-of-the-art CMOS process. A well is implanted into a portion of a substrate such that the well has a higher doping concentration than the substrate. A first diffusion region is then implanted into the substrate such that at least a portion of the first diffusion is disposed within the well. In addition, a second diffusion is implanted into the substrate separated from the well such that the second diffusion region is disposed entirely outside the well. A channel region is disposed between the first and second regions and gate is disposed over the channel region to form the high voltage transistor. Since the second diffusion region is disposed entirely outside the well in the lower doped substrate, a higher junction breakdown voltage is realized. Furthermore, with the transistor layout described herein having at least a portion of the first diffusion region disposed within the well, adequate device isolation is also realized.
