    Abstract: A transistor structure including a substrate, a transistor device, a split buried layer, and a second buried layer is provided. The substrate has a device region. The transistor device is located in the device region. The split buried layer is located under the transistor device in the substrate and includes first buried layers separated from each other. The second buried layer is located under the split buried layer in the substrate and connects the first buried layers. The second buried layer and the split buried layer have a first conductive type. The transistor structure may have a higher breakdown voltage.

    Abstract: A manufacturing method for a shallow trench isolation. First, a substrate is provided, a hard mask layer and a patterned photoresist layer are sequentially formed on the substrate, at least one trench is then formed in the substrate through an etching process, the hard mask layer is removed. Afterwards, a filler is formed at least in the trench and a planarization process is then performed on the filler. Since the planarization process is performed only on the filler, so the dishing phenomenon can effectively be avoided.

    Abstract translation: 浅沟槽隔离的制造方法。 首先，提供基板，在基板上顺序地形成硬掩模层和图案化的光致抗蚀剂层，然后通过蚀刻工艺在基板中形成至少一个沟槽，去除硬掩模层。 然后，至少在沟槽中形成填料，然后对填料进行平面化处理。 由于仅在填料上进行平坦化处理，所以可以有效地避免凹陷现象。

    Abstract: A method of forming a semiconductor device is disclosed. A gate structure is formed on a substrate. The gate structure includes a dummy gate and a spacer at a sidewall of the dummy gate. A dielectric layer is formed on the substrate outside of the gate structure. A metal hard mask layer is formed to cover tops of the dielectric layer and the spacer and to expose a surface of the gate structure. The dummy gate is removed to form a gate trench. A low-resistivity metal layer is formed on the metal hard mask layer filling in the gate trench. The low-resistivity metal layer outside of the gate trench is removed. The metal hard mask layer is removed.
