    摘要: Operation of complex integrated circuits at low temperatures may be enhanced by providing active heating elements within the integrated circuit so as to raise the temperature of at least critical circuit portions at respective operational phases, such as upon power-up. Consequently, enhanced cold temperature performance may be obtained on the basis of existing process elements in order to provide design stability without requiring extensive circuit simulation or redesign of well-established circuit architectures.

    摘要: By introducing additional strain-inducing mechanisms on the basis of stress memorization techniques, the performance of NMOS transistors may be significantly increased, thereby reducing the imbalance between PMOS transistors and NMOS transistors. By amorphizing and re-crystallizing the respective material in the presence of a mask layer at various stages of the manufacturing process, a drive current improvement of up to approximately 27% has been observed, with the potential for further performance gain.

    摘要: A method of forming a semiconductor structure comprises providing a semiconductor substrate comprising a first transistor element and a second transistor element. The first transistor element comprises at least one first amorphous region and the second transistor element comprises at least one second amorphous region. A stress-creating layer is formed over the first transistor element. The stress-creating layer does not cover the second transistor element. A first annealing process is performed. The first annealing process is adapted to re-crystallize the first amorphous region and the second amorphous region. After the first annealing process, a second annealing process is performed. The stress-creating layer remains on the semiconductor substrate during the second annealing process.
