摘要:
By providing an interlayer dielectric material with different removal rates, a desired minimum material height above gate electrode structures of sophisticated transistor devices of the 65 nm technology or 45 nm technology may be obtained. The reduced removal rate above the gate electrode may thus provide enhanced process robustness during the planarization of the interlayer dielectric layer stack prior to the formation of contact elements.

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.

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.

By incorporating germanium material into thermal sensing diode structures, the sensitivity thereof may be significantly increased. In some illustrative embodiments, the process for incorporating the germanium material may be performed with high compatibility with a process flow for incorporating a silicon/germanium material into P-channel transistors of sophisticated semiconductor devices. Hence, temperature control efficiency may be increased with reduced die area consumption.
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.

摘要:
A new technique enables providing a stress-inducing alloy having a highly stress-inducing region and a region which is processable by standard processing steps suitable for use in a commercial high volume semiconductor device manufacturing environment. The regions may be formed by a growth process with a varying composition of the growing material or by other methods such as ion implantation. The highly stress-inducing region near the channel region of a transistor may be covered with an appropriate cover.
