Dublin, Oct. 4, 2013 (GLOBE NEWSWIRE) -- Research and Markets ( has announced the addition of the "STMicroelectronics L3G4IS Dual-Core 3-Axis MEMS Gyroscope Reverse Costing Analysis" report to their offering.

The first dual-core MEMS gyroscope enabling both user interface (UI) and optical image stabilization (OIS) applications simultaneously.

Using a new THELMA Process - Extracted from the Nokia Lumia 920.

While Digital Still Cameras commonly use MEMS based optical image stabilization, it was not included in smartphones. The Nokia Lumia 920 is the first smartphone featuring an OIS function.

Instead of using two dedicated sensors, Nokia chose to integrate a single gyroscope for both gesture recognition and camera image stabilization, allowing cost and board space savings.

The L3G4IS is the first two-in-one gyroscope able to sense motion with low noise and high sensitivity for OIS applications and to sense coarse movements with low sensitivity for UI applications. Assembled in the mainstream LGA 4x4mm package, the L3G4IS integrated in the Nokia Lumia 920 includes a MEMS die manufactured with the standard ST's THELMA and glass-frit wafer bonding processes. We also had access to a version of the component including a smaller MEMS die featuring a Gold-Gold thermocompression wafer bonding process and a modified THELMA process manufactured with new materials for the buried polysilicon layer used for the electrical interconnections.

This report provides a complete teardown of the MEMS gyro with:
