DESCRIPTION
The first MEMS Gyroscope from Maxim Integrated in the industry smallest 3x3mm package Following the purchase of MEMS manufacturer SensorDynamics in 2011, Maxim releases its first MEMS Gyroscope reference with a very accurate and cost effective component. The MAX21000 continues to use the PSM-X2 process jointly developed by SensorDynamics and the Fraunhofer Institute for Silicon Technology. This technology platform includes a proprietary surface micromachining process to build the mechanical structures and a gold silicon eutectic wafer bonding allowing an hermetic encapsulation of the gyro sensor. Assembled in a LGA 3.0x3.0x0.9mm package, the MAX21000 is a low power consumption (5.4mA) and high accuracy 3-axis gyroscope targeted for mobile applications. The report is including a detailed technical and cost comparison with state of the art 3x3mm MEMS gyros from STMicroelectronics, Bosch Sensortec and InvenSense. Surprisingly, Maxim is able to provide a very competitive component due to an important silicon are a reduction.

• This full reverse costing study has been conducted to provide insight on technology data,
manufacturing cost and selling price of the Maxim MAX21000 3-Axis Gyroscope.
• The MAX21000 is an ultra-accurate, low power consumption MEMS gyroscope assembled in
industry’s smallest and thinnest 3.0 x 3.0 x 0.9mm LGA package. It is suitable for both user interface
(UI) and optical image stabilization (OIS) applications.
• The MEMS sensor is manufactured with the PSM-X2 process jointly developed by SensorDynamics
(acquired by Maxim in 2011) and the Fraunhofer Institute for Silicon Technology.
This technology platform includes a proprietary surface micromachining process to build the
mechanical structures and a gold silicon eutectic wafer bonding allowing an hermetic
encapsulation of the gyro sensor.
• Compared with state of the art 3x3mm MEMS gyroscopes supplied by STMicroelectronics and
Bosch Sensortec, the new design developed by Maxim for this reference offers 28% to 35%
reduction in silicon area for the MEMS die, enabling a significant cost advantage. Nevertheless,
Maxim uses a fabless model for this component reducing considerably this advantage.
• Another comparison with latest generation of InvenSense Gyro using also a fabless approach lets
appear that the silicon area reduction obtained by Maxim will not be sufficient to compete with
innovating processes like the one of InvenSense or mCube.

The reverse costing analysis is conducted in 3 phases:
Teardown analysis
• Package is analyzed and measured• The dies are extracted in order to get overall data: dimensions, main blocks, pad number and pin out, die marking• Setup of the manufacturing process.
Costing analysis
• Setup of the manufacturing environment• Cost simulation of the process steps
Selling price analysis
• Supply chain analysis• Analysis of the selling price

Reverse costing analysis represents the best cost/price evaluation given the publically available data, and estimates completed by industry experts.
Given the hypothesis presented in this analysis, the major sources of correction would lead to a +/- 10% correction on the manufacturing cost (if all parameters are cumulated)
These results are open for discussion. We can reevaluate this circuit with your information. Please contact us:
