An OSAT Perspective On Semiconductor Market Trends


For the semiconductor industry, 2022 was a very interesting year. On one hand, it witnessed shortages in the supply chain. On the other hand, the macro-economic situation turned and demand for several consumer and computing devices plummeted. A trade war with China and ensuing localization of supply chain with passage of CHIPS act took shape in 2022. The auto industry is still recovering from t... » read more

Heterogeneous Integration: Fertile Ground For Medical And Biotech Innovation


Sensing components in medical and biotech devices often place severe restrictions on the assembly methods that can be employed, which is part of what is driving heightened demand for heterogeneous integration (HI). It is the newest frontier for the medical and biotech manufacturing services industry to contribute our own innovations by developing the processes to build these unique combinations... » read more

Addressing Three Big Challenges In Silicon Realization


There is no better way to gain insight into prevailing technical challenges than bringing together industry experts to share experiences and proposed solutions. Silicon realization—the ability to design and build today’s complex semiconductors—is one domain with no shortage of challenges. The quest for the best power, performance, and area, and delivery of first-time-right silicon, requir... » read more

Heterogeneous Chip Assembly Helps Optimize Medical And Wearable Devices


Heterogeneous integration (HI) has significant implications for the medical, health, and wearables industry. At Promex, we utilize a variety of complex assembly processes to achieve HI for medical and biotech applications. This post will take a closer look at the processes associated with assembling these classes of devices. Figure 1 provides a high-level overview of our approach. Nearly eve... » read more

Heterogeneous Integration: Correcting Overlay Errors On Advanced Integrated Circuit Substrates (AICS)


By John Chang, with Corey Shay, James Webb, and Timothy Chang For high-performance computing, artificial intelligence, and data centers, the path ahead is certain, but with it comes a change in substrate format and processing requirements. Instead of relying on the quest for the next technology node to bring about future device performance gains, manufacturers are charting a future based inc... » read more

Heterogeneous Integration Co-Design Won’t Be Easy


The days of “throwing it over the wall” are over. Heterogeneous integration is ushering in a new era of silicon chip design with collaboration at its core—one that lives or dies on seamless interaction between your analog and digital IC and package design teams. Heterogeneous integration is the use of advanced packaging technologies to combine smaller, discrete chiplets into one syste... » read more

Heterogeneous Integration: Exposing Large Panels With Fewer Shots


By John Chang, with Corey Shay, James Webb, and Timothy Chang The More than Moore era is upon us, as manufacturers increasingly turn to back-end advances to meet the next-generation device performance gains of today and tomorrow. In the advanced packaging space, heterogeneous integration is one tool helping accomplish these gains by combining multiple silicon nodes and designs inside one pac... » read more

Thermal Simulation Of DSMBGA And Coupled Thermal-Mechanical Simulation Of Large Body HDFO


Electronic packaging has continued to become more complex with higher device count, higher power densities and Heterogeneous Integration (HI) becoming more common. In the mobile space, systems that were once separate components on a printed circuit board (PCB) have now been relocated along with all their associated passive devices and interconnects into single System in Package (SiP) style suba... » read more

Heterogeneous IC Packaging: Optimizing Performance And Cost


Leading integrated circuit (IC) foundries are already shipping 7-nm and 5-nm wafers and 3-nm product qualifications are ongoing. Wafer costs continue to soar as high transistor density requires ever more expensive processes to fabricate them. Even if defect densities can remain relatively flat as new nodes emerge, the cost per unit area of silicon increases nonlinearly. These economics have pla... » read more

Heterogeneous Integration Device Assembly: Key To Enabling Additional Innovations


Heterogeneous integration (HI) improves device functionality by expanding the types of parts and physical configurations combined with silicon chips. Different parts add new functions – with minimal additional volume – thus increasing overall functionality per unit volume. By comparison, classic methods employed to build electronic products, e.g., circuit boards or metal boxes, increase pro... » read more
