Patent number: 10556791Abstract: Monolithic integration of microelectromechanical systems (MEMS) sensors with complementary oxide semiconductor (CMOS) electronics for pressure sensors is a very challenging task. This is primarily due to the requirement for a very high quality thin diaphragm to provide the pressure dependent MEMS deformation that can be sensed and, when seeking absolute rather than relative pressure sensors, a sealed reference cavity. Accordingly, a new manufacturing process is established based upon back-etching and bonding of a monolithic absolute silicon carbide (SiC) capacitive pressure sensor. Beneficially, the process embeds the critical features of the MEMS within a shallow trench formed within the silicon substrate and then processing the CMOS circuit. The process further benefits as it maintains that those elements of the MEMS element fabrication process that are CMOS compatible are implemented concurrently with those CMOS steps as well as the metallization steps.Type: GrantFiled: July 19, 2017Date of Patent: February 11, 2020Assignee: King Abdulaziz City for Science and TechnologyInventors: Tariq Salim Alsaiary, Ibrahim Abdullah Alhomoudi

Patent number: 9754724Abstract: The present invention generally relates to a MEMS digital variable capacitor (DVC) (900) and a method for manufacture thereof. The movable plate (938) within a MEMS DVC should have the same stress level to ensure proper operation of the MEMS DVC. To obtain the same stress level, the movable plate is decoupled from CMOS ground during fabrication. The movable plate is only electrically coupled to CMOS ground after the plate has been completely formed. The coupling occurs by using the same layer (948) that forms the pull-up electrode as the layer that electrically couples the movable plate to CMOS ground. As the same layer couples the movable plate to CMOS ground and also provides the pull-up electrode for the MEMS DVC, the deposition occurs in the same processing step. By electrically coupling the movable plate to CMOS ground after formation, the stress in each of the layers of the movable plate can be substantially identical.Type: GrantFiled: June 4, 2014Date of Patent: September 5, 2017Assignee: CAVENDISH KINETICS, INC.Inventors: Robertus Petrus Van Kampen, Richard L.

Patent number: 9689766Abstract: A pressure sensor, comprising: a substrate having a measuring membrane, and an electrically conductive cover layer, which has electrical contact elements and is electrically isolated from the substrate by an insulating layer. The cover layer is divided in such a manner that two independent measurements of the respective resistance between two contact elements are possible in two regions electrically isolated from one another. The regions of the cover layer serve to shield external electromagnetic influences from the sensor elements of the measuring membrane, to detect damage to the measuring membrane, as well as for determining exact temperature.Type: GrantFiled: September 24, 2013Date of Patent: June 27, 2017Assignee: Endress + Hauser GmbH + Co.
