The present invention provides an access method and a system for a Machine-Type Communication (MTC) device, and an MTC device. The method comprises the steps of: an MTC device sending, when performing channel request, a channel request cause value and a random reference value to a Base Station Subsystem (BSS) (100), and the BSS sending the received channel request cause value and random reference value back to the MTC device when completing channel allocation (101). The present invention distinguishes the MTC services from other non-MTC services through the channel request cause value, that is, when the cause values are different, the collision will not occur even if the random reference values are the same, thus reducing the probability of the random reference value collision, implementing the effective management for access operations of large numbers of MTC devices, and avoiding the influence of random reference value collision on the normal implementation of original services.

摘要:
The present invention provides a method of forming asymmetric field-effect-transistors. The method includes forming a gate structure on top of a semiconductor substrate, the gate structure including a gate stack and spacers adjacent to sidewalls of the gate stack, and having a first side and a second side opposite to the first side; performing angled ion-implantation from the first side of the gate structure in the substrate, thereby forming an ion-implanted region adjacent to the first side, wherein the gate structure prevents the angled ion-implantation from reaching the substrate adjacent to the second side of the gate structure; and performing epitaxial growth on the substrate at the first and second sides of the gate structure. As a result, epitaxial growth on the ion-implanted region is much slower than a region experiencing no ion-implantation. A source region formed to the second side of the gate structure by the epitaxial growth has a height higher than a drain region formed to the first side of the gate structure by the epitaxial growth. A semiconductor structure formed thereby is also provided.
