  • Patent number: 11913806
    Abstract: Efficient 3D geospatial mapping is disclosed. A 3D geospatial map of an area of interest is generated from 2D satellite imagery. The 2D imagery is preprocessed to generate a point cloud of the area of interest. The point cloud is optimized by removing atmospheric clouds and shadows. A 3D geographical information system (GIS) map with multiple levels of details (LOD) is generated.

  • Patent number: 11848348
    Abstract: Device and method of forming the device are disclosed. The method includes providing a substrate prepared with a complementary metal oxide semiconductor (CMOS) region and a sensor region. A substrate cavity is formed in the substrate in the sensor region, the substrate cavity including cavity sidewalls and cavity bottom surface and a membrane which serves as a substrate cavity top surface. The cavity bottom surface includes a reflector. The method also includes forming CMOS devices in the CMOS region, forming a micro-electrical mechanical system (MEMS) component on the membrane, and forming a back-end-of-line (BEOL) dielectric disposed on the substrate having a plurality of interlayer dielectric (ILD) layers. The BEOL dielectric includes an opening to expose the MEMS component. The opening forms a BEOL cavity above the MEMS component.

  • Patent number: 11845653
    Abstract: A complementary metal oxide semiconductor (CMOS) device integrated with micro-electro-mechanical system (MEMS) components in a MEMS region is disclosed. The MEMS components, for example, are infrared (IR) thermosensors. The MEMS sensors are integrated on the CMOS device heterogeneously. For example, a CMOS wafer with CMOS devices and interconnections as well as partially processed MEMS modules is bonded with a MEMS wafer with MEMS structures, post CMOS compatibility issues are alleviated. Post integration process to complete the devices includes forming contacts for interconnecting the sensors to the CMOS components as well as encapsulating the devices with a cap wafer using wafer-level vacuum packaging.

  • Patent number: 10937824
    Abstract: Device and method of forming a device are disclosed. The device includes a substrate with a transistor component disposed in a transistor region and a micro-electrical mechanical system (MEMS) component disposed on a membrane over a lower sensor cavity in a hybrid region. The MEMS component serves as thermoelectric-based infrared sensor, a thermopile line structure which includes an absorber layer disposed over a portion of oppositely doped first and second line segments. A back-end-of-line (BEOL) dielectric is disposed on the substrate having a plurality of inter layer dielectric (ILD) layers with metal and via levels. The ILD layers include metal lines and via contacts for interconnecting the components of the device. The metal lines in the metal levels are configured to define a BEOL or an upper sensor cavity over the lower sensor cavity, and metal lines of a first metal level of the BEOL dielectric are configured to define a geometry of the MEMS component.

  • Patent number: 10403674
    Abstract: Device and method of forming the devices are disclosed. The method includes providing a substrate prepared with transistor and sensor regions. The substrate is processed by forming a lower sensor cavity in the substrate, filling the lower sensor cavity with a sacrificial material, forming a dielectric membrane in the sensor region, forming a transistor in the transistor region and forming a micro-electrical mechanical system (MEMS) component on the dielectric membrane in the sensor region. The method continues by forming a back-end-of-line (BEOL) dielectric having a plurality of interlayer dielectric (ILD) layers with metal and via levels disposed on the substrate for interconnecting the components of the device. The metal lines in the metal levels are configured to define an upper sensor cavity over the lower sensor cavity, and metal lines of a first metal level of the BEOL dielectric are configured to define a geometry of the MEMS component.
