In one example, the system includes an inertial measurement unit (IMU) for acquiring multi-axis motion data at a first sampling rate, and an orientation sensor to acquire orientation data at a second sampling rate that is varied based on the multi-axis motion data.

Abstract: A structure for semiconductor devices having a high-dielectric constant dielectric film on the top surface of the structure can be used to form semiconductor devices that are composed of hybrid bonded structures with reduced dielectric surface area and reduced pitch for metal studs. For example, the dielectric constant of the dielectric film can be about or greater than 7 or 8. A semiconductor device can be formed by hybrid bonding the dielectric film of the structure to a dielectric film of a similar structure. A dielectric film-oxide-metal-substrate structure can be formed with the dielectric film on the top surface of the stack. A multi-material etch can be used etch features in the dielectric film and the oxide in a dielectric film-oxide-metal-substrate stack. A chemical-mechanical polishing technique can be used to precisely form the surface of the structure in preparation for hybrid bonding.
