    摘要: A semiconductor device may include a semiconductor substrate, first and second source/drain regions on a surface of the semiconductor substrate, and a channel region on the surface of the semiconductor substrate with the channel region between the first and second source/drain regions.

    摘要: A method for forming a p-channel metal-oxide semiconductor(PMOS) device is suitable for reducing the width of change of a threshold voltage by preventing a deterioration of a uniformity of dopants due to out diffusion and segregation of the dopants implanted into channel regions. The method includes the steps of: forming a channel region below a surface of a semiconductor substrate; activating dopants implanted into the channel region through a first annealing process performed twice by rising temperature velocities different to each other; forming a gate oxidation layer and a gate electrode on the semiconductor substrate subsequently; forming a source/drain regions at both sides of the gate electrode in the semiconductor substrate; and activating dopants implanted into the source/drain regions through a second annealing process performed at the same conditions of the first annealing process.

    摘要: A method of selective epitaxial growth for a semiconductor device is disclosed. By employing a hydrogen gas as a selectivity promoting gas in addition to a chlorine gas conventionally used, the method can guarantee the selectivity of epitaxial growth and further increase the growth rate of an epitaxial layer. The method begins with loading a semiconductor substrate into a reaction chamber. The substrate has a mask layer, which is selectively formed thereon to define a first portion exposed beyond the mask layer and a second portion covered by the mask layer. Next, a source gas is supplied into the reaction chamber so that the source gas is adsorbed on the first portion and thus the epitaxial layer is selectively formed on the first portion. Then, the selectivity promoting gas including the H2 gas into the reaction chamber, whereby any nucleus of semiconductor material is removed from the mask layer. Thereafter, the source gas and the selectivity promoting gas are sequentially and repeatedly supplied until the semiconductor epitaxial layer is grown to a desired thickness.
