Challenges Grow For Creating Smaller Bumps For Flip Chips


New bump structures are being developed to enable higher interconnect densities in flip-chip packaging, but they are complex, expensive, and increasingly difficult to manufacture. For products with high pin counts, flip-chip [1] packages have long been a popular choice because they utilize the whole die area for interconnect. The technology has been in use since the 1970s, starting with IBM�... » read more

Managing Yield With EUV Lithography And Stochastics


Identifying issues that actually affect yield is becoming more critical and more difficult at advanced nodes, but there is progress. Although they are closely related, yield management and process control are not the same. Yield management seeks to maximize the number of functioning devices at the end of the line. Process control focuses on keeping each individual device layer within its des... » read more

Next Gen Laser Assisted Bonding (LAB) Technology


In the semiconductor market, there are many applications including smartphone, tablets, central processing units (CPUs), artificial intelligence (AI), data cloud and more that are expecting rapid growth. Among them, CPU data processing, AI and data cloud require much higher power consumption than smart phones or tablets. For the higher power applications, Flip Chip ball grid array (FCBGA) or 2.... » read more

The Impact Of Metal Gate Recess Profile On Transistor Resistance And Capacitance


In logic devices such as finFETs (field-effect transistors), metal gate parasitic capacitance can negatively impact electrical performance. One way to reduce this parasitic capacitance is to optimize the metal gate recess dimensions. However, there are limits to reducing this capacitance if you simply remove more of the metal material, since this can modify capacitance unexpectedly through chan... » read more

Reflections On Photomask Japan 2023: Embracing The Era Of Curvilinear Masks


In April, 2023, I had the privilege of participating in Photomask Japan 2023 (PMJ2023), a web conference that brought together experts and enthusiasts in the field. The conference commenced with an enlightening keynote talk by Dr. Kurt Ronse of imec on the status and challenges of the high NA EUV ecosystem, presenting roadmaps for the introduction of high NA EUV. I would like to express my grat... » read more

MEMS & Sensors Market Forecast: Impact Of Semiconductor Industry Slowdown


Of all technologies, MEMS and sensors stand out for their far-reaching promise to improve lives across segments such as Internet of Things (IoT), wearables, smart home, digital health, precision agriculture, autonomous vehicles, robotics, and environmental monitoring. Little wonder, then, that the growth of the MEMS and sensor design and manufacturing industry is among the hottest topics at ... » read more

Breaking The 1M RAID5 Write IOPS Barrier


In today’s data-centric age, enormous amounts of data are generated, stored and processed at an unprecedented rate. Businesses are utilizing this data to make better decisions, drive greater efficiencies, develop more desirable products, improve profitability and ultimately increase user satisfaction. To continue deriving a high degree of value from a rapidly-expanding data flow, today’s en... » read more

Photonic Debond: Scalability And Advancements


Advanced packaging technology has continuously evolved over the past 10-20 years to become a major driving force in improving integrated circuit (IC) performance. This improvement in IC performance is assisted by the ability to place specialized components near each other for shorter interconnects in the IC packages. Temporary bond and debond (TB/DB) is an enabling technique for this work. TB/D... » read more

Challenges In Packaging 5G And 6G


Millimeter wave frequencies are essential for transferring more data more quickly, but they also require different packaging technology to minimize loss and drift. That opens up a number of tradeoffs around antenna in package, antenna on package, flexible circuits, and different substrates. Curtis Zwenger, vice president of R&D at Amkor Technology, talks about a host of new challenges rangi... » read more
