Abstract
A method of forming a Micro-Electro-Mechanical System (MEMS) includes forming a lower electrode on a first insulator layer within a cavity of the MEMS. The method further includes forming an upper electrode over another insulator material on top of the lower electrode which is at least partially in contact with the lower electrode. The forming of the lower electrode and the upper electrode includes adjusting a metal volume of the lower electrode and the upper electrode to modify beam bending.
Claims16
A Micro-Electro-Mechanical System (MEMS) structure comprising:
- a moveable beam comprising at least one insulator layer on a lower electrode;
- and
- an upper electrode over the at least one insulator layer,
- wherein the lower electrode has a slotted layout to match a metal volume of the lower electrode with a metal volume of the upper electrode.
