About Yole Group 

During the past few years, the consumer market for MEMS pressure sensors has become significant, mainly due to these sensors’ use in smartphones, wearables, drones, and e-cigarettes.

To encapsulate the increasing interest in the consumer pressure sensor market, Yole SystemPlus provides a deep comparative review of the technology, supply chain, and cost of 12 MEMS pressure sensors. The reference products come from the main suppliers in the market: Bosch, Infineon, TDK-Invensense, STMicroelectronics, and Alps Alpine. Yole SystemPlus has analyzed these pressure sensors to provide insights into their structure, technology, manufacturing processes, and production cost. We studied the packaging, application-specific integrated circuit (ASIC) dies, and MEMS dies, furnishing detailed optical and scanning electron microscope (SEM) pictures of the MEMS structures, package, and cross-section. We’ve also identified the MEMS manufacturing processes.

We note and compare the technological evolutions for each manufacturer, including the differences between the main competitors. The MEMS pressure sensors are compared in terms of structures and technologies, package type, dimensions, and cross-section. For the MEMS dies, the differences in die size and sensing technologies are made. For the ASIC dies, we compare size and technology node. Finally, we make the comparison of the MEMS pressure sensors’ cost in detail for the MEMS components, the ASICs, and the packaging costs.

This report includes the survey data and supply chain evaluation from our consumer teardown of smartphones and smartwatches supplied by Apple, Samsung, Google, Sony, LG, Garmin, and Fitbit. The most recent electronic components were selected for our analysis, and compared to the previous generations.

This report also shows the technology change from piezoresistive to capacitive by BOSCH in its pressure sensor devices, and includes the evolution of the ASIC integration inside the package for the BOSCH sensors found in the latest Apple iPhones and watches.   Moreover, this study includes an analysis of the latest pressure sensor supplied by TDK-InvenSense, in which the monolithic integration of the MEMS and the ASIC dies were changed for the two separated chips in order to enable extended battery life for always-on applications.

Lastly, this report provides an overview of the MEMS microphone and MEMS pressure sensor packaged in the same module and supplied by Goertek – a new solution which helps OEM integrators to save the place and reduce the cost of manufacturing.
