    摘要: A semiconductor device includes a channel region; a gate dielectric over the channel region; and a gate electrode over the gate dielectric. A first source/drain region is adjacent the gate dielectric, wherein the first source/drain region is a semiconductor region and of a first conductivity type. A second source/drain region is on an opposite side of the channel region than the first source/drain region, wherein the second source/drain region is a metal region. A pocket region of a second conductivity type opposite the first conductivity type is horizontally between the channel region and the second source/drain region.

    摘要: A method is provided for improving Idsat in NMOS and PMOS transistors. A silicon nitride etch stop layer is deposited by a PECVD technique on STI and silicide regions and on sidewall spacers during a MOSFET manufacturing scheme. A dielectric layer is formed on the nitride and then contact holes are fabricated through the dielectric layer and nitride layer to silicide regions and are filled with a metal. For NMOS transistors, silane and NH3 flow rates and a 400° C. temperature are critical in improving NMOS short channel Idsat. Hydrogen content in the nitride is increased by higher NH3 and SiH4 flow rates but does not significantly degrade HCE and Vt. With PMOS transistors, deposition temperature is increased to 550° C. to reduce hydrogen content and improve HCE and Vt stability.

    摘要: A method for forming a field effect transistor device employs a self-aligned etching of a semiconductor substrate to form a recessed channel region in conjunction with a pair of raised source/drain regions. The method also provides for forming and thermally annealing the pair of source/drain regions prior to forming a pair of lightly doped extension regions within the field effect transistor device. In accord with the foregoing features, the field effect transistor device is fabricated with enhanced performance.

    摘要: A method for forming a field effect transistor device within a semiconductor product employs a patterned dummy layer first as an ion implantation mask layer when forming a pair of source/drain regions, and then as a mandrel layer for forming a pair of patterned sacrificial layers which define an aperture of linewidth and location corresponding to the patterned dummy layer. A pair of sacrificial spacer layers and a gate electrode are then formed self-aligned within the aperture. The pair of patterned sacrificial layers and the pair of sacrificial spacer layers are then stripped and the gate electrode is employed as a mask for ion implanting forming a pair of lightly doped extension regions partially overlapping the pair of source/drain regions within the semiconductor substrate.

    摘要: Within a method for fabricating a semiconductor integrated circuit microelectronic fabrication, there is employed a planarizing method for forming, in a self aligned fashion, a patterned second gate electrode material layer laterally adjacent but not over a patterned first gate electrode material layer, such that upon further patterning of the patterned first gate electrode material layer and the patterned second gate electrode material layer there may be formed a first gate electrode over a first active region of a semiconductor substrate and a second gate electrode over a laterally adjacent second active region of the semiconductor substrate. The method is particularly useful within the context of complementary metal oxide semiconductor (CMOS) semiconductor integrated circuit microelectronic fabrications.
