    摘要: A method of selectively forming a spacer on a first class of transistors and devices formed by such methods. The method can include depositing a conformal first deposition layer on a substrate with different classes of transistors situated thereon, depositing a blocking layer to at least one class of transistors, dry etching the first deposition layer, removing the blocking layer, depositing a conformal second deposition layer on the substrate, dry etching the second deposition layer and wet etching the remaining first deposition layer. Devices may include transistors of a first class with larger spacers compared to spacers of transistors of a second class.

    摘要: A semiconductor device and method to form a semiconductor device is described. The semiconductor includes a gate stack disposed on a substrate. Tip regions are disposed in the substrate on either side of the gate stack. Halo regions are disposed in the substrate adjacent the tip regions. A threshold voltage implant region is disposed in the substrate directly below the gate stack. The concentration of dopant impurity atoms of a particular conductivity type is approximately the same in both the threshold voltage implant region as in the halo regions. The method includes a dopant impurity implant technique having sufficient strength to penetrate a gate stack.
