US07579643B2 Capacitor having high electrostatic capacity, integrated circuit device including the capacitor and method of fabricating the same 有权
具有高静电容量的电容器，包括该电容器的集成电路器件及其制造方法

Capacitor having high electrostatic capacity, integrated circuit device including the capacitor and method of fabricating the same
Abstract:
A capacitor may include a first electrode, a second electrode, a low dielectric layer, and/or a high dielectric layer. The first electrode may include at least one first electrode branch. The second electrode may face the first electrode and include at least one second electrode branch. The low dielectric layer may be formed between the first electrode branch and the second electrode branch. The high dielectric layer may be formed between the first electrode branch and the second electrode branch. The high dielectric layer may have a higher dielectric constant than the low dielectric layer.
Abstract(Chinese):

电容器可以包括第一电极，第二电极，低介电层和/或高电介质层。 第一电极可以包括至少一个第一电极分支。 第二电极可面向第一电极并且包括至少一个第二电极分支。 低电介质层可以形成在第一电极分支和第二电极分支之间。 高电介质层可以形成在第一电极分支和第二电极分支之间。 高介电层可以具有比低介电层更高的介电常数。
