    Abstract: Provided is a method of fabricating a semiconductor device, including the following. A first material layer, a second material layer and a mask layer are formed on a substrate. A portion of the second material layer is removed by performing a first etching process with the mask layer as a mask, so as to expose the first material layer and form a first pattern layer and a second pattern layer. A portion of the first material layer is removed by performing a second etching process with the mask layer as a mask, so as to expose a portion of the substrate. A portion of the substrate is removed by performing a third etching process with the mask layer as a mask, so as to form first trenches and second trenches. Sidewalls of the second trenches and a surface of the substrate form at least two different angles.

    Abstract: A semiconductor device and a manufacturing method of the same are provided. The semiconductor device includes a substrate, a first dielectric layer, a first conductive layer, and an isolation structure. The substrate has a trench. The first dielectric layer is disposed on the substrate between two neighboring trenches. The first conductive layer is disposed on the first dielectric layer. The isolation structure, including a step zone and a recessed zone, is disposed in the trench, wherein an upper surface of the step zone is higher than an upper surface of the first dielectric layer.
