    Abstract: Some embodiments of the present disclosure relate to a transistor device formed in a semiconductor substrate containing dopant impurities of a first impurity type. The transistor device includes channel composed of a delta-doped layer comprising dopant impurities of the first impurity type, and configured to produce a peak dopant concentration within the channel. The channel further includes a layer of carbon-containing material overlying the delta-doped layer, and configured to prevent back diffusion of dopants from the delta-doped layer and semiconductor substrate. The channel also includes of a layer of substrate material overlying the layer of carbon-containing material, and configured to achieve steep retrograde dopant concentration profile a near a surface of the channel. In some embodiments, a counter-doped layer underlies the delta-doped layer configured to reduce leakage within the semiconductor substrate, and includes dopant impurities of a second impurity type, which is opposite the first impurity type.

    Abstract: Some embodiments of the present disclosure relate to an epitaxially grown replacement channel region within a transistor, which mitigates the variations within the channel of the transistor due to fluctuations in the manufacturing processes. The replacement channel region is formed by recessing source/drain and channel regions of the semiconductor substrate, and epitaxially growing a replacement channel region within the recess, which comprises epitaxially growing a lower epitaxial channel region over a bottom surface of the recess, and epitaxially growing an upper epitaxial channel region over a bottom surface of the recess. The lower epitaxial channel region retards dopant back diffusion from the upper epitaxial channel region, resulting in a steep retrograde dopant profile within the replacement channel region. The upper epitaxial channel region increases carrier mobility within the channel. The replacement channel region provides improved drive current, thereby enabling better performance and higher yield.

    Abstract: The present disclosure relate to an integrated chip having long-channel and short-channel transistors having channel regions with different doping profiles. In some embodiments, the integrated chip includes a first gate electrode arranged over a first channel region having first length, and a second gate electrode arranged over a second channel region having a second length greater than the first length. The first channel region and the second channel region have a dopant profile, respectively along the first length and the second length, which has a dopant concentration that is higher by edges than in a middle of the first channel region and the second channel region. The dopant concentration is also higher by the edges of the first channel region than by the edges of the second channel region.
