Differential capacitor structure |
摘要 |
A differential capacitor structure (10) formed overlying a substrate (12) having a middle layer (24) disposed between a lower layer (18) and an upper layer (28). The lower layer (18) is a static layer that is formed on the substrate (12), the middle layer (24) has a moveable component and is a dynamic layer attached to the substrate (12) using semi-circular tether supports (42), and the upper layer is a static layer that is anchored to the substrate (12). The semi-circular tether supports (42) are formed from a homogeneous material and provide structural stiffness to support the middle layer (24) in space and also provide stress relief.
