Governments Begin To Shape Metrology Directions


Disruptions to the global semiconductor supply chain caused by the COVID-19 pandemic had a severe impact in nearly every sector of the worldwide economy, and especially the worldwide semiconductor market. Due to a shortage of chips, the global auto industry alone suffered a $210 billion loss in 2021, accompanied by a 7.7 million unit production drop, according to AlixPartners, a global consulti... » read more

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

Enabling New Functionality In Medtech And Biotech Devices


Medtech and biotech devices are uniquely suited to benefit from emerging electronic capabilities – specifically, the kind of electronics design, packaging and assembly offerings that are Promex’s specialty. With that said, these markets present a variety of manufacturing challenges and demands that require heterogeneous integration (HI) to address. This two-part blog post provides a high... » read more

3D Structures Challenge Wire Bond Inspection


Adding more layers in packages is making it difficult, and sometimes impossible, to inspect wire bonds that are deep within the different layers. Wire bonds may seem like old technology, but it remains the bonding approach of choice for a broad swath of applications. This is particularly evident in automotive, industrial, and many consumer applications, where the majority of chips are not de... » 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. Click here to read more. » read more

Big Changes Ahead In Power Delivery, Materials, And Interconnects


Part one of this forecast looked at evolving transistor architectures and lithography platforms. This report examines revolutions in interconnects and packaging. When it comes to device interconnects, it’s hard to beat copper. Its low resistivity and high reliability have served the industry exceedingly well as both on-chip interconnect and wires between chips. But in logic chips, with int... » read more

Mini-Consortia Forming Around Chiplets


Mini-consortia for chiplets are sprouting up across the industry, driven by demands for increasing customization in tight market windows and fueled by combinations of hardened IP that have been proven in silicon. These loosely aligned partnerships are working to develop LEGO-like integration models for highly specific applications and end markets. But they all are starting small, because it'... » read more

Panel Tackles Chiplet Packaging Challenges


QP Technologies recently exhibited at the first Chiplet Summit, held January 24-26 in San Jose, California. Dick Otte, CEO of our parent company Promex Industries, participated on a panel titled “Best Packaging for Chiplets Today.” Moderated by Nobuki Islam with JCET Group, the packaging panel also included Daniel Lambalot, Alphawave Semi; Laura Mirkarimi, Adeia; Syrus Ziai, Eliyan; and Mik... » read more

Managing Thermal-Induced Stress In Chips


At advanced nodes and in the most advanced packages, physics is no one's friend. Escalating density, smaller features, and thinner dies make it more difficult to dissipate heat, and they increase mechanical stress. On the flip side, thinner dielectrics and tighter spaces make it more difficult to insulate and protect against that heat, and in conjunction with those smaller features and higher d... » read more

Bump Reliability is Challenged By Latent Defects


Thermal stress is a well-known problem in advanced packaging, along with the challenges of mechanical stress. Both are exacerbated by heterogenous integration, which often requires mingling materials with incompatible coefficients of thermal expansion (CTE). Effects are already showing up and will likely only get worse as package densities increase beyond 1,000 bumps per chip. “You comb... » read more
