THE METHOD FOR FORMING FIN FIELD EFFECT TRANSISTOR (FINFET) DEVICE STRUCTURE |
摘要 |
Methods for forming the fin field effect transistor (FinFET) device structure are provided. The method includes forming first fin structures and second fin structures on a first region and a second region of a substrate, respectively, and a number of the first fin structures is greater than a number of the second fin structures. The method also includes forming a sacrificial layer on the first fin structures and the second fin structures and performing an etching process to the sacrificial layer to form an isolation structure on the substrate. |

1. A method for forming a fin field effect transistor (FinFET) device structure, comprising:
forming first fin structures and second fin structures on a first region and a second region of a substrate, respectively, wherein a number of the first fin structures is greater than a number of the second fin structures; forming a sacrificial layer on the first fin structures and the second fin structures; and performing an etching process to the sacrificial layer to form an isolation structure on the substrate. |
