摘要:
A spacer covering a sidewall of a contact plug includes a relatively more damaged first portion and a relatively less damaged second portion. An interface of the first and second portions of the spacer is spaced apart from a metal silicide layer of the contact plug. Thus reliability of the semiconductor device may be improved. Related fabrication methods are also described.
摘要:
The disclosure provides a semiconductor fabricating apparatus and a method of fabricating a semiconductor device using the same. In some embodiments, the apparatus may synchronize low-frequency, high-frequency and direct current (DC) powers that are applied to an electrode. The low-frequency power may have a non-sinusoidal waveform. Thus, reliability and reproducibility of a semiconductor fabrication process may be improved. In other embodiments, the apparatus may include a first low-frequency power generator generating a first low-frequency power having a sinusoidal waveform and a second low-frequency power generator generating a second low-frequency power having a non-sinusoidal waveform.

摘要:
Methods for forming a semiconductor device including fine patterns are provided. The method may include forming a mask layer including first holes spaced apart from each other in a first direction and a second direction. The method may also include forming local mask patterns on the mask layer and forming a sacrificial layer on the mask layer filling the first holes and surrounding the local mask patterns. The local mask patterns may be offset from the first holes in the first direction and the second direction. The method may further include removing the local mask patterns to form openings in the sacrificial layer exposing the mask layer and etching the mask layer through the opening to form second holes in the mask layer.
