Structures and Methods for Forming Fin Structures |
摘要 |
Structures and methods are provided for forming fin structures. A first fin structure is formed on a substrate. A shallow-trench-isolation structure is formed surrounding the first fin structure. At least part of the first fin structure is removed to form a cavity. A first material is formed on one or more side walls of the cavity. A second material is formed to fill the cavity, the second material being different from the first material. At least part of the STI structure is removed to form a second fin structure including the first material and the second material. At least part of the first material that surrounds the second material is removed to fabricate semiconductor devices. |

1. A method comprising:
forming a first fin structure on a substrate; forming a first material surrounding the first fin structure; removing at least part of the first fin structure to form a cavity; forming a second material to fill the cavity, the second material being different from the first material; and removing at least part of the first material that surrounds the second material to fabricate semiconductor devices. |
