    Abstract: CMOS integrated circuit devices include an electrically insulating layer and an unstrained silicon active layer on the electrically insulating layer. An insulated gate electrode is also provided on a surface of the unstrained silicon active layer. A Si1-xGex layer is also disposed between the electrically insulating layer and the unstrained silicon active layer. The Si1-xGex layer forms a first junction with the unstrained silicon active layer and has a graded concentration of Ge therein that decreases monotonically in a first direction extending from a peak level towards the surface of the unstrained silicon active layer. The peak Ge concentration level is greater than x=0.15 and the concentration of Ge in the Si1-xGex layer varies from the peak level to a level less than about x=0.1 at the first junction. The concentration of Ge at the first junction may be abrupt. More preferably, the concentration of Ge in the Si1-xGex layer varies from the peak level where 0.2

    Abstract: Methods of erasing a non-volatile memory device having discrete charge trap sites between a semiconductor substrate and a gate include applying a negative voltage to a gate at least partially spaced apart from a semiconductor substrate by a charge storage layer providing discrete charge trap sites. A first positive voltage is applied to a source formed in the semiconductor substrate adjacent to one sidewall of the gate. A second positive voltage, which is equal to or less than the first positive voltage, is applied to a drain formed in the semiconductor substrate adjacent to the gate and located opposite the source.

    Abstract: 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.

    Abstract: 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.
