Abstract
The present invention relates to semiconductor devices, such as microelectromechanical (MEMS) devices, with improved resilience during manufacturing. In one embodiment, a MEMS device includes a MEMS structure; a substrate situated parallel to the MEMS structure and positioned a first distance from the MEMS structure; and a bump stop structure formed on the substrate between the substrate and the MEMS structure, wherein the bump stop structure substantially traces a perimeter of the substrate, wherein the bump stop structure extends from the substrate to a second distance from the MEMS structure, and wherein the second distance is greater than zero and less than the first distance.
