    摘要: An enclosed, flat covered leadless pressure sensor assembly suitable for extreme environment operation including dynamic, ultra-high temperature heating, light and heat flash, and high-speed, flow-related environments. The pressure sensor assembly comprises a substrate comprising a micromachined sensing diaphragm defined on a first side. A cover is attached to the first side of the substrate such that it covers at least the sensing diaphragm. The top surface of the cover is substantially flat, thereby promoting uniformity in the distribution of stress and thermal effects across a top surface of the cover.
