Novel Molded FCBGA Package Platform For Highly Reliable Automotive Applications


The conventional flip chip ball grid array (FCBGA) package platform has wide industry usage and provides high electrical performance. However, as high performance requirements increased, it encounters significant challenges. FCBGA packages frequently encounter underfill cracks after long term reliability or harsh reliability test conditions for automotive devices. Figure 1 shows the typical und... » read more

How Die Dimensions Challenge Assembly Processes


Multi-die assemblies are becoming more common and more complex due to technology advancements and market demands, but differing die dimensions are making this process increasingly challenging. To fully enable a multi-chiplet ecosystem, standardized component handling and interfaces are needed. The underlying concept is similar to LEGO blocks that simply snap together, yet it's nowhere near t... » read more

Chip Industry Week In Review


Chinese firms imported almost $26 billion worth of chipmaking machinery, according to fresh trade data released by China’s General Administration of Customs this week, Bloomberg reports. Meanwhile, the global semiconductor manufacturing industry continued to show signs of improvement in Q2 2024 with significant growth of IC sales, stabilizing capital expenditure, and an increase in install... » read more

3.5D: The Great Compromise


The semiconductor industry is converging on 3.5D as the next best option in advanced packaging, a hybrid approach that includes stacking logic chiplets and bonding them separately to a substrate shared by other components. This assembly model satisfies the need for big increases in performance while sidestepping some of the thorniest issues in heterogeneous integration. It establishes a midd... » read more

Increasing Roles For Robotics In Fabs


Different types of robots with greater precision and mobility are beginning to be deployed in semiconductor manufacturing, where they are proving both reliable and cost-efficient. Static robots have been used for years inside of fabs, but they now are being supplemented by collaborative robots (cobots), autonomous mobile robots (AMRs), and autonomous humanoid robots to meet growing and widen... » read more

Current Characterization Of Various Cu RDL Designs In Wafer Level Packages (WLP)


Copper (Cu) redistribution layer (RDL) technology is used to interconnect chips in various high current Wafer Level Packaging (WLP) applications. Typically, Cu RDLs with thicknesses of 5-9 µm and widths of 5-20 µm are used for high current sourcing. In this case, the temperature of the Cu RDL metal line increases due to the Joule heat generated when current passes through the metal line. If a... » read more

Driving Cost Lower and Power Higher With GaN


Gallium nitride is starting to make broader inroads in the lower-end of the high-voltage, wide-bandgap power FET market, where silicon carbide has been the technology of choice. This shift is driven by lower costs and processes that are more compatible with bulk silicon. Efficiency, power density (size), and cost are the three major concerns in power electronics, and GaN can meet all three c... » read more

Chip Industry Week in Review


Okinawa Institute of Science and Technology proposed a new EUV litho technology using only four reflective mirrors and a new method of illumination optics that it claims will use 1/10 the power and cost half as much as existing EUV technology from ASML. Applied Materials may not receive expected U.S. funding to build a $4 billion research facility in Sunnyvale, CA, due to internal government... » read more

Chip Industry Week In Review


The U.S. Department of Commerce and Amkor Technology signed a deal to provide up to $400 million in funding, under the CHIPS and Science Act, to build a previously announced end-to-end advanced packaging plant. The combined funding is expected to total about $2 billion. The new facility will add some 2,000 jobs in Peoria, Arizona. The SK hynix Board approved its Yongin Semiconductor Cluster... » read more

Precision Patterning Options Emerge For Advanced Packaging


The chip industry is ratcheting up investments in advanced packaging as it strives to keep pace with demands for increased functionality and higher performance, including novel patterning technologies that can reduce costs and speed time to market. Success in advanced packages is partly dependent on effectively managing the interconnectivity between the chips, which requires increasingly pre... » read more
