高度隔离的集成电感器及其制作方法
摘要：
本发明公开了一种电感器，其一实施例包含：一第一金属走线线圈，其为一开回路形态，且置于一第一金属层；一第二金属走线线圈，其为一开回路形态，且置于该第一金属层；以及一第三金属走线线圈，其为一闭回路形态，且置于一第二金属层。于上述实施例中，该第一金属走线线圈被适当地布局，以在一第一轴线方面是实质地对称；该第二金属走线线圈被适当地布局，以在一第二轴线方面是该第一金属走线线圈的一近似镜像；以及从一顶视观点而言，该第三金属走线线圈被适当地布局，以大略地围绕该第一金属走线线圈与该第二金属走线线圈二者的大部分。
摘要（英）：

The invention discloses an inductor. One embodiment thereof comprises a first coil of metal trace configured in an open loop topology and placed in a first metal layer; a second coil of metal trace configured in an open loop topology and placed in the first metal layer; and a third coil of metal trace configured in a closed loop topology and placed in a second metal layer, wherein: the first coilof metal trace is laid out to be substantially symmetrical with respect to a first axis, the second coil of metal trace is laid out to be approximately a mirror image of the first coil of metal tracewith respect to a second axis, and the third coil of metal trace is laid out to enclose a majority portion of both the first coil of metal trace and the second coil of metal trace from a top view perspective.
