摘要： Method, device, and system for deriving keys are provided in the field of mobile communications technologies. The method for deriving keys may be used, for example, in a handover process of a User Equipment (UE) from an Evolved Universal Terrestrial Radio Access Network (EUTRAN) to a Universal Terrestrial Radio Access Network (UTRAN). If a failure occurred in a first handover, the method ensures that the key derived by a source Mobility Management Entity (MME) for a second handover process of the UE is different from the key derived for the first handover process of the UE. This is done by changing input parameters used in the key derivation, so as to prevent the situation in the prior art that once the key used on one Radio Network Controller (RNC) is obtained, the keys on other RNCs can be derived accordingly, thereby enhancing the network security.

The manufacturing method comprises steps of: firstly creating a gate region, then performing high dose source and drain light doping to form the lightly doped N-type source region and lightly doped N-type drain region; forming an insulation spacer surrounding the gate region; performing large tilt heavily-doped P ion implantation in an inclined direction via a mask with an opening at the position of the N type Si source region and implanting P ions into the space between the N type Si source region and the N type drain region to form a heavily-doped P-type region; finally forming a metal layer on the N type Si source region, then allowing the reaction between the metal layer and the remained Si material underneath to form silicide by heat treatment. In the device prepared by the method of the present invention, an ohmic contact is formed between the silicide and the heavily-doped P-type region nearby in order to release the holes accumulated in body region of the SOI MOS device and eliminate floating body effects thereof. Besides, the device of the present invention also has following advantages, such as limited chip area, simplified fabricating process and great compatibility with traditional CMOS technology.

摘要： A Ge and Si hybrid material inversion mode GAA (Gate-All-Around) CMOSFET includes a PMOS region having a first channel, an NMOS region having a second channel and a gate region. The first channel and the second channel have a circular-shaped cross section and are formed of n-type Ge and p-type Si, respectively; the surfaces of the first channel and the second channel are substantially surrounded by the gate region; a buried oxide layer is disposed between the PMOS region and the NMOS region and between the PMOS or NMOS region and the Si substrate to isolate them from one another. In an inversion mode, current flows through the overall cylindrical channel, so as to achieve high carrier mobility, reduce low-frequency noises, prevent polysilicon gate depletion and short channel effects and increase the threshold voltage of the device.
