Abstract
A microelectromechanical systems (MEMS) structure having a stopper integrated with a MEMS substrate is provided. A first substrate has a dielectric layer arranged over the first substrate. The dielectric layer includes a device opening. A second substrate is arranged over and bonded to the first substrate through the dielectric layer. The second substrate includes a deflectable element arranged over the device opening. A stopper is integrated with the second substrate and protrudes from the deflectable element over the device opening. A method for manufacturing the MEMS structure is also provided.
