    摘要: A method for fabricating a CMOS transistor is disclosed. The present invention provides a method for producing a CMOS transistor having enhanced performance since a short channel characteristic and operation power can be controlled by the duplicate punch stop layer of the pMOS region and the operation power of the nMOS is also controlled by dopant concentration of the duplicated LDD region combined by the first LDD region and the second LDD region.

    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. An insulating layer pattern may be on the channel region, a first conductive layer pattern may be on the insulating layer, and a second conductive layer pattern may be on the first conductive layer pattern. The insulating layer pattern may be between the first conductive layer pattern and the channel region, and the first conductive layer pattern may include boron doped polysilicon with a surface portion having an accumulation of silicon boronide. The first conductive layer pattern may be between the second conductive layer pattern and the insulating layer pattern, and the second conductive layer pattern may include tungsten. Related methods are also discussed.

    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.
