    • A metal-insulator-metal (MIM) capacitor structure and method of manufacturing thereof. A plurality of MIM capacitor patterns is formed in two or more insulating layers. The insulating layers may comprise a via layer and a metallization layer of a semiconductor device. A top portion of the top insulating layer is recessed in a region between at least two adjacent MIM capacitor patterns. When the top plate material of the MIM capacitors is deposited, the top plate material fills the recessed area of the top insulating layer between the adjacent MIM capacitor pattern, forming a connecting region that couples together the top plates of the adjacent MIM capacitors. A portion of the MIM capacitor bottom electrode may be formed in a first metallization layer of the semiconductor device.
    • 金属绝缘体金属(MIM)电容器结构及其制造方法。 多个MIM电容器图案形成在两个或更多个绝缘层中。 绝缘层可以包括半导体器件的通孔层和金属化层。 顶部绝缘层的顶部凹陷在至少两个相邻的MIM电容器图案之间的区域中。 当MIM电容器的顶板材料沉积时,顶板材料填充相邻MIM电容器图案之间的顶部绝缘层的凹陷区域,形成将相邻的MIM电容器的顶板耦合在一起的连接区域。 MIM电容器底部电极的一部分可以形成在半导体器件的第一金属化层中。
