摘要： Multiple types of gate stacks are formed on a doped semiconductor well. A high dielectric constant (high-k) gate dielectric is formed on the doped semiconductor well. A metal gate layer is formed in one device area, while the high-k gate dielectric is exposed in other device areas. Threshold voltage adjustment oxide layers having different thicknesses are formed in the other device areas. A conductive gate material layer is then formed over the threshold voltage adjustment oxide layers. One type of field effect transistors includes a gate dielectric including a high-k gate dielectric portion. Other types of field effect transistors include a gate dielectric including a high-k gate dielectric portion and a first threshold voltage adjustment oxide portions having different thicknesses. Field effect transistors having different threshold voltages are provided by employing different gate dielectric stacks and doped semiconductor wells having the same dopant concentration.

摘要： A method and structure to scale metal gate height in high-k/metal gate transistors. A method includes forming a dummy gate and at least one polysilicon feature, all of which are formed from a same polysilicon layer and wherein the dummy gate is formed over a gate metal layer associated with a transistor. The method also includes selectively removing the dummy gate while protecting the at least one polysilicon feature. The method further includes forming a gate contact on the gate metal layer to thereby form a metal gate having a height that is less than half a height of the at least one polysilicon feature.
