The future of IC packaging and emerging trends in the industry

Updated: Sep 29, 2023

What are the Key Drivers of IC Packaging Innovation Today?

Integrated circuits (ICs) have played a vital role in the technological advancements of the modern world. They are present in almost every electronic device we use, from smartphones to home appliances, and even automobiles. As the demand for more powerful, efficient, and compact electronic devices continues to grow, the IC packaging industry must adapt and evolve to meet these requirements. In this blog, we will explore the current trends in IC package types and packaging technologies and discuss the emerging technologies that will shape the future of the industry.

IC Packaging Overview

IC packaging is the process of encapsulating an IC in a protective material that provides electrical connections and mechanical support. The chip packages must protect the IC from external factors such as moisture, temperature fluctuations, and physical damage while providing a connection to the outside world. The package material is typically a ceramic or plastic substrate, and the connections are made through metallic pads on the IC and the package. The package is then mounted onto a printed circuit board (PCB) or other electronic devices, completing the assembly process. Historically, IC packaging has followed a trend of increasing pin count, shrinking package size, and higher performance.

The earliest chip packages had a few pins and were large enough to be soldered by hand. With the introduction of surface mount technology (SMT) in the 1980s, package sizes decreased, and pin counts increased, leading to more compact and efficient electronic devices. Today, IC packages with several thousand pins are commonplace, and many are manufactured with advanced techniques such as through-silicon vias (TSVs) and flip-chip bonding.

Current Trends in IC Packaging

The IC packaging industry is continuously evolving, and new technologies are emerging to meet the demands of the market. Some of the current trends in IC packaging include:

Fan-Out Wafer Level Packaging (FO-WLP)

FO-WLP is a relatively new packaging technology that is gaining popularity due to its high-density interconnects, low form factor, and cost-effective manufacturing process. FO-WLP uses a thin wafer as a substrate, which allows for a larger die size than traditional packages. The IC is placed on the wafer, and the package is formed by molding the IC in a protective material. The package is then sawed into individual units, and the connections are made using a redistribution layer (RDL) and solder bumps. FO-WLP offers several advantages over traditional packaging methods, such as lower cost, improved performance, and reduced form factor.

System-in-Package (SiP)

SiP is a packaging technology that combines multiple ICs, passive components, and other elements into a single package. SiP allows for the integration of multiple functions into a single package, reducing the size, weight, and cost of the overall system. SiP is particularly useful for complex systems such as mobile devices, where space is at a premium. The packaging technology can be customized to meet the specific requirements of the system, providing a high degree of flexibility in design.

2.5D and 3D Packaging

2.5D and 3D packaging are advanced packaging techniques that offer several advantages over traditional packaging methods. In 2.5D packaging, multiple dies are stacked on top of each other, connected through TSVs, and integrated into a single package. This technique offers higher interconnect density and shorter interconnect lengths, resulting in better performance and reduced power consumption. In 3D packaging, the dies are stacked vertically, with the TSVs running through the dies. This technique allows for higher interconnect density, lower power consumption, and reduced form factor.

Heterogeneous Integration

Heterogeneous integration is a packaging technique that involves combining different ICs, such as sensors, memory, and logic, into a single package. Heterogeneous integration offers several benefits, including reduced power consumption, improved performance, and smaller form factor. This packaging technique is expected to gain popularity in the future, as it allows for the integration of different functions and technologies, resulting in higher performance and better reliability.

Advanced Materials

Advanced materials are an emerging trend in IC packaging. These materials, such as copper, graphene, and nanomaterials, offer several advantages over traditional materials, including better thermal management, higher conductivity, and better mechanical properties. These materials are expected to become increasingly popular in the future, as they can improve the performance and reliability of IC packaging.

Shrinking Form Factor

The shrinking form factor trend of IC packaging is a result of several factors, including the demand for smaller and more portable electronic devices such as smartphones and wearables. This demand has led to a need for more compact IC packages that can fit within these devices' slim form factors. Additionally, there is a need for higher performance and functionality in electronic devices, which requires more complex and sophisticated packaging technologies to maintain the required electrical connections between the chip and the outside world.

High Density Packaging

High density packaging is an advanced technology that enables the creation of powerful, small-sized electronic devices, including smartphones, tablets, and laptops. It achieves this by tightly packing miniaturized electronic components together, utilizing manufacturing techniques such as surface-mount technology and ball grid array. High density packaging provides benefits such as reduced manufacturing costs, improved energy efficiency, and increased portability. However, it also poses challenges, such as the need for sophisticated testing and thermal management solutions. Overall, high density packaging has transformed the electronics industry, leading to the creation of compact, powerful, and energy-efficient devices that have changed the way we live and work.


The future of IC packaging is promising, with several emerging trends that are expected to revolutionize the industry. The use of 3D packaging techniques, FOWLP, SiP, heterogeneous integration, and advanced materials are some of the emerging trends that will shape the future of IC packaging. These trends will lead to smaller form factors, improved performance, better reliability, and reduced costs, which will benefit both manufacturers and consumers alike. As the demand for faster, more powerful, and smaller devices continues to grow, the IC packaging industry will continue to evolve to meet the demand of the market.
