    Abstract: PROBLEM TO BE SOLVED: To provide a structure having the superposition of stressed layers bringing a compressive stress into the channel of a p-type MOSFET device and a tensile stress into the channel of an n-type MOSFET device on each gate stack and including the p-type MOSFET device and the n-type MOSFET device that are adjacent, and to provide a method of manufacturing the same. SOLUTION: One of a p-type MOSFET device or an n-type MOSFET device has a height shorter than that of the other adjacent device, and the boundary of the shorter device of the two devices is defined by a discontinuity, i.e. an opening part in the stressed layers superposed on the shorter device. In a preferable method for forming the device, a single stressed layer is formed on the gate stack having different heights for forming a first type stress in the substrate under the gate stack. An opening part is formed in the stressed layer at a distance from the shorter gate stack, so that a second type stress is formed under the shorter gate stack. COPYRIGHT: (C)2007,JPO&INPIT

    Abstract: Methods of stressing a channel of a transistor with a replaced gate and related structures are disclosed. A method may include providing an intrinsically stressed material over the transistor including a gate thereof; removing a portion of the intrinsically stressed material over the gate; removing at least a portion of the gate, allowing stress retained by the gate to be transferred to the channel; replacing (or refilling) the gate with a replacement gate; and removing the intrinsically stressed material. Removing and replacing the gate allows stress retained by the original gate to be transferred to the channel, with the replacement gate maintaining (memorizing) that situation. The methods do not damage the gate dielectric. A structure may include a transistor having a channel including a first stress that is one of a compressive and tensile and a gate including a second stress that is the other of compressive and tensile.
