Abstract: The present disclosure provides a transistor device. The transistor device includes an active region surrounded by an isolation structure, a gate structure disposed over the active region and the isolation structure, and a source/drain disposed in the active region. The gate structure includes a body portion extending in a first direction, a head portion extending in a second direction, and a pair of wing portions disposed at two opposite sides of the body portion. The first direction and the second direction are perpendicular to each other. Each of the wing portions is in contact with the head portion and the body portion.

Abstract: The present disclosure provides a semiconductor structure including a substrate, a bottom gate portion disposed in the substrate, a top gate portion stacked over the bottom gate portion, a first channel layer sandwiched between the top gate portion and the bottom gate portion, and a source/drain region disposed in the substrate at two opposite sides of the top gate portion.

Abstract: The present disclosure provides a transistor device and a semiconductor layout structure. The transistor device includes an active region disposed in a substrate, a gate structure disposed over the active region, and a source/drain region disposed at two opposite sides of the gate structure. The active region includes a first region including a first length, a second region including a second length less than the first length, and a third region between the first region and the second region. The gate structure includes a first portion extending in a first direction and a second portion extending in a second direction perpendicular to the first direction. The first portion is disposed over at least the third region of the active region, and the second portion is disposed over at least a portion of the third region and a portion of the second region.
