Abstract
The present invention provides a laterally diffused metal-oxide-semiconductor (LDMOS) transistor and a manufacturing method thereof. The LDMOS transistor includes a semiconductor substrate, an insulation structure, agate structure, and a plurality of floating electrodes. The insulation structure is disposed in the semiconductor substrate. The gate structure is disposed on the semiconductor substrate. The floating electrodes are embedded in the insulation structure, wherein the floating electrode closest to the gate structure protrudes from a top surface of the insulation structure or the gate structure includes at least one branch portion embedded in the insulation structure, and the floating electrodes are separated from the gate structure.
