  • Patent number: 9144089
    Abstract: 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.

  • Patent number: 9105741
    Abstract: A method of forming a semiconductor structure may include forming at least one fin and forming, over a first portion of the at least one fin structure, a gate. Gate spacers may be formed on the sidewalls of the gate, whereby the forming of the spacers creates recessed regions adjacent the sidewalls of the at least one fin. A first epitaxial region is formed that covers both one of the recessed regions and a second portion of the at least one fin, such that the second portion extends outwardly from one of the gate spacers. A first epitaxial layer is formed within the one of the recessed regions by etching the first epitaxial region and the second portion of the at least one fin. A second epitaxial region is formed at a location adjacent one of the spacers and over the first epitaxial layer within one of the recessed regions.

  • Patent number: 9023697
    Abstract: A method of forming a semiconductor structure includes growing an epitaxial doped layer over an exposed portion of a plurality of fins. The epitaxial doped layer combines the exposed portion of the fins to form a merged source and drain region. An implantation process occurs in the fins through the epitaxial doped layer to change the crystal lattice of the fins to form amorphized fins. A nitride layer is deposited over the semiconductor structure. The nitride layer covers the merged source and drain regions. A thermal treatment is performed in the semiconductor structure to re-crystallize the amorphized fins to form re-crystallized fins. The re-crystallized fins, the epitaxial doped layer and the nitride layer form a strained source and drain region which induces stress to a channel region.

  • Publication number: 20150037947
    Abstract: A conductive strap structure in lateral contact with a top semiconductor layer is formed on an inner electrode of a deep trench capacitor. A cavity overlying the conductive strap structure is filled a dielectric material to form a dielectric capacitor cap having a top surface that is coplanar with a topmost surface of an upper pad layer. A semiconductor mandrel in lateral contact with the dielectric capacitor cap is formed. The combination of the dielectric capacitor cap and the semiconductor mandrel is employed as a protruding structure around which a fin-defining spacer is formed. The semiconductor mandrel is removed, and the fin-defining spacer is employed as an etch mask in an etch process that etches a lower pad layer and the top semiconductor layer to form a semiconductor fin that laterally wraps around the conductive strap structure. An access finFET is formed employing two parallel portions of the semiconductor fin.
