多层电容器及其制造方法
摘要：
本发明公开一种多层电容器及其制造方法。该电容器元件包括第一电极、第二电极、第三电极、第一介电层以及第二介电层。第一电极与电容器元件的第一电极接点电性耦合。第二电极位于第一电极的下方且与电容器元件的第二电极接点电性耦合。第二电极与第一电极电性绝缘。第三电极位于第一电极以及第二电极的下方，第三电极与第二电极电性绝缘并与第一电极电性耦合。第一介电层位于第一电极与第二电极之间，而且第一介电层具有第一介电常数。第二介电层位于第二电极与第三电极之间，而且第二介电层具有第二介电常数。在一实施例中，第二介电常数比第一介电常数至少大五倍。
摘要（英）：

The invention discloses a multilayer capacitors and a method for making the same. The capacitor device may include a first electrode, a second electrode, a third electrode, a first dielectric layer, and a second dielectric layer. The first electrode may be coupled with a first terminal of the capacitor device. The second electrode is under the first electrode and may be coupled with a second terminal of the capacitor device. The second electrode may be electrically isolated from the first electrode. The third electrode is under the first electrode and the second electrode and may be electrically isolated from the second electrode and electrically coupled with the first electrode. The first dielectric layer has a first dielectric constant and may be sandwiched between the first electrode and the second electrode. The second dielectric layer may have a second dielectric constant and may be sandwiched between the second electrode and the third electrode. In one embodiment, the second dielectric constant is at least five times larger than the first dielectric constant.
