Claim Text:
1. A microelectromechanical pressure sensor structure that comprises a body structure and a diaphragm plate, wherein the body structure comprises a planar base and side walls; a first surface extends along the planar base; the side walls extend as a circumference away from the planar base; the diaphragm plate extends on the side walls along a second surface; the planar base, the side walls and the diaphragm plate are attached to each other such that the first surface, the second surface and inner surfaces of the side walls form a hermetically closed gap in a reference pressure; a top edge of the inner surfaces of the side walls forms a circumference of a diaphragm that has a length and a width in the direction of the second surface, wherein the length is in a direction of the longest extent of the diaphragm, and the width is in a direction perpendicular the direction of the length in the direction of the second surface; and the length of the diaphragm is at least three times the width of the diaphragm.
