US Patent 11174153 Package level thermal gradient sensing

A microelectromechanical (MEMS) device may be coupled to a dielectric material at an upper planar surface or lower planar surface of the MEMS device. One or more temperature sensors may be attached to the dielectric material layer. Signals from the one or more temperature sensors may be used to determine a thermal gradient along on axis that is normal to the upper planar surface and the lower planar surface. The thermal gradient may be used to compensate for values measured by the MEMS device.
