Shortages, Challenges Engulf Packaging Supply Chain


A surge in demand for chips is impacting the IC packaging supply chain, causing shortages of select manufacturing capacity, various package types, key components, and equipment. Spot shortages in packaging surfaced in late 2020 and have since spread to other sectors. There are now a variety of choke points in the supply chain. Wirebond and flip-chip capacity will remain tight throughout 2021... » read more

Power Converter Chip Research Booms


Power electronics are booming, fueled by demand ranging from induction chargers for wearable and portable electronics, to charging stations for electric vehicles. An estimated 80% of all U.S. electricity will pass through some form of power converter by 2030, said Yogesh Ramadass, director of power management at Texas Instruments' Kilby Labs. Transportation applications, in particular, deman... » read more

Breaking The 2nm Barrier


Chipmakers continue to make advancements with transistor technologies at the latest process nodes, but the interconnects within these structures are struggling to keep pace. The chip industry is working on several technologies to solve the interconnect bottleneck, but many of those solutions are still in R&D and may not appear for some time — possibly not until 2nm, which is expected t... » read more

The Good, Bad And Unknowns Of Flexible Devices


Flexible hybrid electronics are beginning to proliferate in consumer, medical, and industrial applications due to their comparatively low weight, thin profile, and the ability to literally bend the rules of design. Open any smart phone today and you're likely to find one or more of these flexible boards. Unlike standard printed circuit boards, FHE devices are printed using a combination of r... » read more

New Transistor Structures At 3nm/2nm


Several foundries continue to develop new processes based on next-generation gate-all-around transistors, including more advanced high-mobility versions, but bringing these technologies into production is going to be difficult and expensive. Intel, Samsung, TSMC and others are laying the groundwork for the transition from today’s finFET transistors to new gate-all-around field-effect trans... » read more

The Chip Industry’s Next-Gen Roadmap


Todd Younkin, the new president and chief executive of the Semiconductor Research Corp. (SRC), sat down with Semiconductor Engineering to talk about engineering careers, R&D trends and what’s ahead for chip technologies over the next decade. What follows are excerpts of that conversation. SE: As a U.S.-based chip consortium, what is SRC's charter? Younkin: The Semiconductor Research... » read more

48V Applications Drive Power IC Package Options


The manufacturing process and die get most of the attention, but the packaging plays an important part in enabling and limiting performance, manufacturability, particularly when it comes to reliability of power devices. Given the wide range of underlying semiconductor power-device technologies — “basic” silicon, wide-bandgap silicon carbide (SiC) and gallium nitride (GaN), power levels... » read more

Stronger, Better Bonding In Advanced Packaging


System-in-package integrators are moving toward copper-to-copper direct bonding between die as the bond pitch goes down, making the solder used to connect devices in a heterogenous package less practical. In thermocompression bonding, protruding copper bumps bond to pads on the underlying substrate. In hybrid bonding, copper pads are inlaid in a dielectric, reducing the risk of oxidation. ... » read more

Variation Threat In Advanced Nodes, Packages Grows


Variation is becoming a much bigger and more complex problem for chipmakers as they push to the next process nodes or into increasingly dense advanced packages, raising concerns about the functionality and reliability of individual devices, and even entire systems. In the past, almost all concerns about variation focused on the manufacturing process. What printed on a piece of silicon didn't... » read more

3D NAND’s Vertical Scaling Race


3D NAND suppliers are accelerating their efforts to move to the next technology nodes in a race against growing competition, but all of these vendors are facing an assortment of new business, manufacturing, and cost challenges. Two suppliers, Micron and SK Hynix, recently leapfrogged the competition and have taken the scaling race lead in 3D NAND. But Samsung and the Kioxia-Western Digital (... » read more
