Abstract: A semiconductor device includes an interlayer insulating layer including a first insulating layer on a substrate, and a plurality of interconnections in the first insulating layer. The interlayer insulating layer includes a first region, and a second region including an air gap. The air gap is defined between a pair of the interconnections in the second region. A top surface of the first insulating layer of the first region is lower than a top surface of at least one of the interconnections in the first region.

Abstract: A method of fabricating a semiconductor device including an interlayer insulating layer and interconnections is provided. An interlayer insulating layer is formed on a substrate. An opening is formed in the interlayer insulating layer. A degassing process is performed by irradiating the interlayer insulating layer having the opening with microwaves. A K-value recovery process is performed by irradiating the interlayer insulating layer having the opening with UV light. A conductive layer is formed in the opening. The degassing process and the K-value recovery process are performed as an in-situ process.

Abstract: A semiconductor device including source drain stressors and methods of manufacturing the same are provided. The methods may include forming a recess region in the substrate at a side of a gate pattern, and an inner surface of the recess region may include a first surface of a (100) crystal plane and a second surface of one of {111} crystal planes. The method may further include performing a first selective epitaxial growth (SEG) process to form a base epitaxial pattern on the inner surface of the recess region at a process pressure in a range of about 50 Torr to about 300 Torr.
