How is the evolution of MEMS devices driving packaging and test strategies? 


MEMS are characterized by a wide range of different designs and manufacturing technologies, with no standardized processes. MEMS’ application scope is broad and also very fragmented and diversified – thus, MEMS packaging must always cope with different end-application requirements (i.e. protection in different media, hermeticity, interconnection type, and thermal management).This creates many challenges for the packaging industry, which faces different package configurations (open, closed) for many different application constraints: from the need for low-cost packaging in consumer applications, to the ability to withstand high temperature and harsh environments for automotive and aeronautics packaging.

We estimate that the MEMS packaging market will grow from a market value of $2.56B in 2016 to $6.46B in 2022 – a 16.7% CAGR over this period. Driven by the complexity associated with the move to 5G and therefore the increasing demand for RF filters in 4G/5G, the largest MEMS growth will be for RF MEMS (BAW filters). Optical MEMS (including micro mirrors and micro bolometers) are second with a 28.5% CAGR, driven by consumer, automotive, and security applications. Acoustic and ultrasonic (including microphones) are third. Demand for audio processing is particularly strong, with high unit growth for MEMS microphones targeted at increasingly sophisticated applications that use the microphone to continuously sense what is happening around it, i.e. for smartphones or inside/outside the car, factory, or home.

The MEMS packaging market’s value is growing faster than the MEMS device market’s value: respectively, a 16.7% 2016 -2022 CAGR for packaging versus 14.1% for devices. The first reason for this is that OSATs already have very low package margins due to fierce competition, and it will be difficult for them to lower the cost further. The second reason is the importance of testing. Because every MEMS is different, testing strategies are usually dedicated to one device type and account for a significant fraction of the final cost. The third reason is linked to the packaging’s material cost (i.e. gold and copper), which follows the global cost of raw materials. And the fourth reason is the strong CAGR for certain devices, for example RF MEMS.

MEMS Packaging market forecast by sensor type


Depending on the type of MEMS, either IDMs or OSATs oversee packaging. Today, OSATs own 55% of the MEMS packaging market’s value, while IDMs own 45%. The exact breakdown depends on the MEMS device type. In general, internal tests are conducted by IDMs since functional tests are very MEMS-specific/dependent, and thus confidential. Thus, an OSAT cannot use the same test strategy for different customers.

For RF MEMS, the market leader (Broadcom) does its own packaging. OSATs are involved in oscillators and antenna tuners for fabless and fab-light players, and in some cases for BAW filters. Microbolometers are complex sensors, so packaging and testing is generally done internally by IDMs (Ulis, FLIR) that have developed their own test strategies. Optical MEMS also require special packaging, usually with an optical window. Testing is very complex, so IDMs (i.e. Texas Instruments) usually do the packaging and testing. Indeed, the limited number of players and low volume doesn’t justify subcontracting at OSATs.

For large-volume applications like consumer and automotive, packaging is cost-driven. The inertial MEMS supply chain is quite fragmented: some IDMs keep testing and calibration internal but outsource packaging and assembly, while others do it all. For environmental MEMS, OSATs are involved in gas, pressure, and combo PA&T. And for acoustic MEMS, many microphone vendors outsource to OSATs for packaging and testing.

In MEMS packaging, the market leaders are ASE and Amkor (respectively 27% and 23% market share), followed by JCET/STATS ChipPAC. There are also many other companies with less than 10% market share.

OSAT market share - MEMS Packaging activity


MEMS packaging already has innovative approaches like TSV and open-cavity packages to expose a die to the outer environment (suitable for TPMS, humidity, temperature, gas sensors). And in the long-term, fan-out could also be used in some inertial MEMS and pressure sensors.

Packaging platforms will follow a steady evolution, with changes in the complexity of the existing platforms responding to the growing needs of sensor fusions. Combining several inertial or several environmental sensors in a package is now a reality, and the next step will be to combine inertial and environmental sensors in the same package, similar to how LEDs and photodiodes are integrated today. Thus, the MEMS packaging roadmap will need to integrate the shift from single-die packaging to multi-die packaging.
Packaging platform - Breakdown by MEMS device

For automotive applications, packaging and assembly are even more important and could represent an opportunity for OSATs. Automotive tests require dedicated equipment and may be an interesting opportunity for ATE equipment suppliers. Besides packaging trends, Yole Développement analyzed the test strategy of IDMs and OSATs. Test equipment suppliers are improving testing tools with the implementation of parallel tests for numerous devices, adding new features (i.e. wafer-level tests for known-good die selections) as the big driver for reducing cost.
