The novel transistor structure comprises first and second source/drain (S/D) regions whose top surfaces are lower than a top surface of the channel region of the transistor structure. The method for fabricating the transistor structure starts out with a planar semiconductor layer and a gate stack on top of the semiconductor layer. Then, top regions of the semiconductor layer on opposing sides of the gate stack are removed. Then, regions beneath the removed regions are doped to form lowered S/D regions of the transistor structure

摘要： In producing complementary sets of metal-oxide-semiconductor (CMOS) field effect transistors, including nFET and pFET), carrier mobility is enhanced or otherwise regulated through the reacting the material of the gate electrode with a metal to produce a stressed alloy (preferably CoSi2, NiSi, or PdSi) within a transistor gate. In the case of both the nFET and pFET, the inherent stress of the respective alloy results in an opposite stress on the channel of respective transistor. By maintaining opposite stresses in the nFET and pFET alloys or silicides, both types of transistors on a single chip or substrate can achieve an enhanced carrier mobility, thereby improving the performance of CMOS devices and integrated circuits.

摘要： A semiconductor structure and method of manufacturing is provided. The method of manufacturing includes forming shallow trench isolation (STI) in a substrate and providing a first material and a second material on the substrate. The first material and the second material are mixed into the substrate by a thermal anneal process to form a first island and second island at an nFET region and a pFET region, respectively. A layer of different material is formed on the first island and the second island. The STI relaxes and facilitates the relaxation of the first island and the second island. The first material may be deposited or grown Ge material and the second material may deposited or grown Si:C or C. A strained Si layer is formed on at least one of the first island and the second island.
