This full reverse costing study provides insight into technology data, manufacturing cost and selling price of the BOSCH Inertial Measurement Unit (IMU) three-axis angular rate sensor and three-axis acceleration sensor found in the latest iPhone 14 Pro.

We believe that this IMU is a custom version of BOSCH’s 6-axis device, made for Apple and integrated into the latest iPhone 14 Pro.

With dimensions of 3.0 mm x 3.0 mm x 0.6 mm, it can be integrated into smartphones and wearables.

While it uses the same sensor processes as BOSCH’s previous generation of 6-axis IMU devices, the designs have been changed for both the Micro-ElectroMechanical System (MEMS) accelerometer and the MEMS gyroscope. The component also integrates a new generation of the Application Specific Integrated Circuit (ASIC).

Moreover, the MEMS accelerometer has 7 sensing axes. Each axis ensures the performance of the crash detection function.

Furthermore, the report includes detailed analysis of the new hermetic sealing technology developed by BOSCH called Laser ReSeal. Bosch uses this process in the MEMS gyroscope cavity manufacturing process.

Additionally, the report includes the physical comparison of the package, the MEMS accelerometer and the MEMS gyroscope dies, the ASIC dies for the BOSCH IMUs found in the iPhone 14 Pro and iPhone 13 Pro Max. It also compares the front-end cost of the MEMS gyroscope wafers.
