    摘要: The manufacturing a semiconductor device includes providing a substrate supporting a gate electrode, amorphizing and doping the source/drain regions located on both sides of the gate electrode by performing a pre-amorphization implant (PAI) process and implanting C or N into the source/drain regions in or separately from the PAI process, forming a stress inducing layer on the substrate to cover the amorphized source/drain regions, and subsequently recrystallizing the source/drain regions by annealing the substrate. The stress inducing layer may then be removed. Also, the C or N may be implanted into the entirety of the source/drain regions after the regions have been amorphized, or only into upper portions of the amorphized source/drain regions.

    摘要: A programming method of a non-volatile memory device includes a pre-program of the non-volatile memory device, and a main-program of the pre-programmed non-volatile memory device. The non-volatile memory device may include a tunnel dielectric layer, a charge storage layer, a blocking dielectric layer, and a gate electrode, which are sequentially stacked on a semiconductor substrate. The charge storage layer may be an electrically-floated conductive layer, or a dielectric layer having a trap site. By performing a main-program after performing a pre-program, to increase the threshold voltage of the non-volatile memory device, the program current can be effectively reduced.

A charge storage oxide layer is disposed on the channel region and overlaps part of each of the pair of source/drain regions. A gate electrode is disposed on the charge storage oxide layer. At least one halo implantation region is formed in the semiconductor substrate adjacent to one of the pair of source/drain regions, and overlapping the charge storage oxide layer. A program operation is performed by trapping electrons in the charge storage oxide layer located near the source/drain region where the halo ion implantation region is formed, and an erase operation is performed by injecting holes into the charge storage oxide layer located near the source/drain region where the halo ion implantation region is formed.

    摘要: A semiconductor device having a transistor of gate all around (GAA) type and a method of fabricating the same are disclosed. A SOI substrate composed of a SOI layer, a buried oxide layer and a lower substrate is prepared. The SOI layer has at least one unit dual layer of a silicon germanium layer and a silicon layer. The SOI layer is patterned to form an active layer pattern to a certain direction. An insulation layer is formed to cover the active layer pattern. An etch stop layer is stacked on the active layer pattern covered with the insulation layer. The etch stop layer is patterned and removed at a gate region crossing the active layer pattern at the channel region. The insulation layer is removed at the gate region. The silicon germanium layer is isotropically etched and selectively removed to form a cavity at the channel region of the active layer pattern. In the state that the silicon germanium layer is selectively removed, a gate insulation layer is formed to cover the exposed surface of the active layer pattern. A gate conductivity layer is stacked on the substrate by a chemical vapor deposition (CVD) to fill the gate region including the cavity. The middle part of the channel region of the active layer pattern can be patterned to be divided by multiple patterns that are formed in a line.

    摘要: The present invention provides a semiconductor transistor using an L-shaped spacer and a method of fabricating the same. The semiconductor transistor includes a gate pattern formed on a semiconductor substrate and an L-shaped third spacer formed beside the gate pattern and having a horizontal protruding portion. An L-shaped fourth spacer is formed between the third spacer and the gate pattern, and between the third spacer and the substrate. A high-concentration junction area is positioned in the substrate beyond the third spacer, and a low-concentration junction area is positioned under the horizontal protruding portion of the third spacer. A medium-concentration junction area is positioned between the high- and low-concentration junction areas. A method of fabricating the semiconductor transistor includes a process, where the high- and medium-concentration junction areas are formed simultaneously by the same ion-implantation step and the substrate is annealed before forming the low-concentration junction area.
