 multi-die solutions, including 2.5D, SWIFT and S-Connect.  These multi-chip modules and high-density WLFO solutions enable package level integration of different types and levels of silicon technologies for high performance computing, networking and data center applications.  This is accomplished by combining processors and other chiplets into one packaged module.  Through die partitioning and heterogeneous integration, these modules provide higher functionality at lower total product cost.  

Another important priority is the development of wafer-level and panel-level packages for 2D and 3D implementations.  These wafer-level chip-scale packages and WLFO packages are increasingly the preferred package type for many applications in IoT and mobile devices, including processors, power management integrated circuits (“PMICs”), display drivers and antenna package products.  Our development of Panel Level Fan Out (“PLFO”) technology will permit higher economies of scale for fan-out package devices manufactured on a panel versus wafer basis.  

Another key area is developing highly integrated SiP modules, such as DSMBGA or double-sided molded land grid array packages, to reduce material and processing costs and minimize form factor for wearables and mobile devices.  

We are also developing new applications for the automotive market using existing and new package technologies as higher performance computing, energy efficiency, power distribution and sensor content are used to support new

automotive features including ADAS, infotainment, optical sensors and electric vehicles.  In addition, we are developing high power modules involving SiC-based devices.

Our research and development employees are based in Korea, Portugal, the United States and other locations in Asia.  In 2024, 2023 and 2022, we incurred $163.0 million, $177.5 million and $149.4 million, respectively, of research and development expense. 

SALES AND MARKETING

Our sales offices are located throughout Asia, Europe and the United States.  Our support personnel manage and promote our packaging and test services and provide key customer and technical support.  To provide comprehensive sales and customer service, we typically assign our customers a direct support team consisting of a sales manager, assembly and test technical program managers and both field and factory customer support representatives.  We also support our largest multinational customers from multiple office locations to ensure that we are aligned with their global operational and business requirements.

Our direct support teams are further supported by an extended staff of product, process, quality and reliability engineers, as well as marketing and advertising specialists, information systems technicians and factory personnel
