S are miniaturized mechanical and electro-mechanical devices that can sense and provide information about the physical world and sometimes trigger a response.  Examples of MEMS devices include microphones, accelerometers, airbag deployment sensors, gyrometers, magnetometers and humidity, temperature and pressure sensors.  We also specialize in sensor fusion products which utilize our cavity MEMS platform and combine multiple sensors into a single package.  MEMS packages leverage our expertise in wafer thinning, die stacking, wirebonding and flip chip interconnect to deliver sophisticated products with a very small form factor.  

Advanced System-in-Package Modules

Advanced SiP modules combine multiple semiconductor and other electronic components with different functionalities into a single package.  These modules use wirebond, flip chip or wafer-level interconnect technologies.  Components can include ICs, passive devices (inductors, capacitors, resistors, filters and diplexers), antennas and mechanical parts.

The increasing demand for miniaturization and higher functionality at competitive cost is driving the adoption of advanced SiP in new products.  Advanced SiP modules are used for many applications such as radio frequency (“RF”) and front-end modules, basebands, connectivity, fingerprint sensors, display and touch screen drivers, sensors and MEMS, NAND memory and solid state drives.  Advanced SiP modules are found in many products including smartphones and tablets, automobiles, IoT wearables, high-performance gaming systems, computers and network systems. 

In 2024, 2023 and 2022, we had net sales of approximately $3,085 million, $2,955 million and $2,930 million, respectively, from our advanced SiP modules, which are mostly included in Advanced Products, depending upon the interconnect technology used in the module. 

Test Services

Our Test Services complement our wafer and packaging services across our Advanced and Mainstream Products.  Our test services offer customers the cycle time and cost advantages of co-located turn-key services.  Our test services are used as both an interim step or as the final testing step to ensure screening and rejection of defects, performance grading and overall outgoing quality and reliability.  Interim testing eliminates the manufacturing costs of assembling the defective chips.  Below is a description of our test services: 

Wafer Level Test:  Wafer level test is a manufacturing step performed while a wafer is still in its full form and before being singulated for further package processing.
