The embodiment of the invention discloses a semiconductor device, a manufacturing method, a power module, a power conversion circuit and a vehicle. The semiconductor device includes a semiconductor body including a first surface and a second surface; the device further comprises a well region, a first region and a channel layer, the first region and the channel layer are in contact with each other, the first region is of a first conductive type and located on the first surface, the channel layer is of the first conductive type and located on the first surface, and the well region is of a second conductive type and located on the side, away from the first surface, of the first region and the channel layer; the gate structure is located on the first surface and covers at least part of the channel layer; the drain is located on the second surface; the source electrode is located on the first surface and covers at least part of the first area. The depletion type semiconductor device is in a conducting state in a normal state, negative voltage needs to be applied between the grid electrode and the source electrode to cut off a channel in a cut-off state, response can be made faster, current circulation can be controlled, conduction loss is small, and the depletion type semiconductor device is more suitable for a high-frequency circuit and a switching circuit.

    本发明实施例公开一种半导体器件及制造方法、功率模块、功率转换电路和车辆。该半导体器件包括:半导体本体,包括第一表面和第二表面;还包括阱区、第一区域和沟道层,第一区域和沟道层相互接触,且第一区域设置为第一导电类型且位于第一表面,沟道层设置为第一导电类型且位于第一表面,阱区设置为第二导电类型且位于第一区域和沟道层远离第一表面的一侧;栅极结构位于第一表面并覆盖至少部分沟道层;漏极位于第二表面;源极位于第一表面并覆盖至少部分第一区域。形成耗尽型半导体器件,常态下处于导通状态,截止状态需要给栅极和源极之间加负电压使沟道截止,可以更快的响应并控制电流流通,导通损耗较小,更适用于高频电路和开关电路。
