Transistor and method for forming the same |
摘要 |
The present invention relates to a stress-enhanced transistor and a method for forming the same. The method for forming the transistor according to the present invention comprises the steps of forming a mask layer on a semiconductor substrate on which a gate has been formed, so that the mask layer covers the gate and the semiconductor substrate; patterning the mask layer so as to expose at least a portion of each of a source region and a drain region; amorphorizing the exposed portions of the source region and the drain region; removing the mask layer; and annealing the semiconductor substrate so that a dislocation is formed in the exposed portion of each of the source region and the drain region. |

1. A method for forming a transistor, comprising the steps of:forming a mask layer on a semiconductor substrate on which a gate has been formed, so that the mask layer directly contacts both the gate and the semiconductor substrate;
patterning the mask layer so as to expose at least two portions of each of a source region and a drain region, wherein the patterned mask layer is only formed between adjacent exposed portions in the source region and between adjacent exposed portions in the drain region; amorphorizing the exposed portions of the source region and the drain region; removing the patterned mask layer; and annealing the semiconductor substrate so that a respective dislocation is formed in the respective exposed portion of each of the source region and the drain region. |
