Abstract:
A wavy FET structure includes a semiconductor substrate having a first conductive type, a source doped region and a drain doped region both having a second conductive type, a gate structure, and first and second metal layers. The semiconductor substrate includes a surface and a fin portion formed on the surface. The fin portion has first and second ends along its length direction. The source doped region is formed on the first end and on a first partial region at a lower portion of the first end and contacting the surface. The drain doped region is formed on the second end and on a second partial region at a lower portion of the second end and contacting the surface. The gate structure covers the fin portion. The first metal layer contacts and covers the source doped region. The second metal layer contacts and covers the drain doped region.

Claim (Index 1):
A wavy FET structure, comprising:\n a semiconductor substrate having a first conductive type, wherein the semiconductor substrate comprises a surface and a fin portion formed on the surface, wherein the fin portion has a first end and a second end along a length direction thereof; a source doped region having a second conductive type, wherein the source doped region is formed on the first end of the fin portion, and is formed on a first partial region which is at a lower portion of the first end and in contact with the surface, and is formed at two sides of the first partial region along a lateral direction which is perpendicular to the length direction; a drain doped region having the second conductive type, wherein the drain doped region is formed on the second end of the fin portion, and is formed on a second partial region which is at a lower portion of the second end and in contact with the surface, and is formed at two sides of the second partial region along the lateral direction; a gate structure covering the fin portion and a portion of the surface between the first partial region and the second partial region; a first metal layer contacting and covering the source doped region; and a second metal layer contacting and covering the drain doped region; wherein the source doped region respectively formed at two sides of the first partial region are connected to each other under the surface, and the drain doped region respectively formed at two sides of the second partial region are connected to each other each other under the surface.
