A semiconductor device includes a substrate including a first region and a second region each having an n-type region and a p-type region, wherein the n-type region in the first region includes a silicon channel, the p-type region in the first region includes a silicon germanium channel, and the n-type region and the p-type region in the second region respectively include a silicon channel. A first gate insulating pattern formed of a thermal oxide layer is disposed on the substrate of the n-type and p-type regions in the second region.

Semiconductor devices and methods for fabricating the same

A semiconductor device may include a resistance pattern including a resistance material on a substrate. The resistance pattern may include first and second spaced apart base elements, a bridge element, and first, second, third, and fourth extension elements. The first and second base elements may be substantially parallel, and the bridge element may be connected between respective center portions of the first and second spaced apart base elements. The first and second extension elements may be connected to opposite ends of the first base element and may extend toward the second base element, and the third and fourth extension elements may be connected to opposite ends of the second base element and may extend toward the first base element. Related methods are also discussed.

Semiconductor devices including resistor elements comprising a bridge and base elements and related methods

In a CMOS semiconductor device using a silicon germanium gate and a method of fabricating the same, a gate insulating layer, a conductive electrode layer that is a seed layer, a silicon germanium electrode layer, and an amorphous conductive electrode layer are sequentially formed on a semiconductor substrate. A photolithographic process is then carried out to remove the silicon germanium electrode layer in the NMOS region, so that the silicon germanium layer is formed only in the PMOS region and is not formed in the NMOS region.

CMOS transistor having different PMOS and NMOS gate electrode structures and method of fabrication thereof

A method of fabricating a semiconductor device forms a shallow source/drain region after a deep source/drain region. First, a gate insulating layer including a gate pattern and a gate electrode are formed on a semiconductor substrate. A buffer insulating layer, a first insulating layer, and a second insulating layer are then sequentially formed on the entire surface of the gate pattern and the semiconductor substrate. A first spacer is formed on the first insulating layer at both sidewalls of the gate pattern by etching the second insulating layer. A deep source/drain region is then formed on the semiconductor substrate as aligned by the first spacer. The first spacer is removed. Next, an offset spacer is formed at both sidewalls of the gate pattern by etching the first insulating layer. Finally, a shallow source/drain region is formed on the semiconductor substrate adjacent to the deep source/drain region as aligned by the offset spacer.

Method of fabricating a semiconductor device having a shallow source/drain region

An SRAM capable of reducing the overall area consumed by the circuit and capable of improving the mobility and operational characteristics of a PMOS transistor is provided. The SRAM is formed on an SOI substrate having first and second active areas. A first access NMOS transistor and a first inverter, which is constituted by a first drive NMOS transistor and a first load PMOS transistor, are formed on the first active area of the SOI substrate. A second access NMOS transistor and a second inverter, which is constituted by a first drive NMOS transistor and a first load PMOS transistor, are formed on the second active area of the SOI substrate. Here, the channels of the first and second load PMOS transistors extend so that carriers move in a [110] silicon crystallization growth direction. In each active area, the drain (or source) of an access NMOS transistor, the drain of a drive NMOS transistor, and the drain of a load PMOS transistor contact one another in a shared region. Because the SRAM is formed on the SOI substrate, the size of the resulting chip can be reduced. Also, because the channels of the first and second load PMOS transistors extend so that carriers move in the [110] silicon crystallization growth direction, the mobility of the PMOS transistors is improved.
