Hybrid Bonding Basics: What Is Hybrid Bonding?


Hybrid bonding is the key to paving an innovative future in advanced packaging. Hybrid bonding provides a solution that enables higher bandwidth and increased power and signal integrity. As the industry is looking to enhance the performance of final devices through scaling system-level interconnections, hybrid bonding provides the most promising solution with the ability to integrate several di... » read more

Fan-Out Packaging Gets Competitive


Fan-out wafer-level packaging (FOWLP) is a key enabler in the industry shift from transistor scaling to system scaling and integration. The design fans out the chip interconnects through a redistribution layer instead of a substrate. Compared to flip-chip ball grid array (FCBGA) or wire bonds, it creates lower thermal resistance, a slimmer package, and potentially lower costs. Yet, if the h... » read more

A Novel Photosensitive Permanent Bonding Material Designed For Polymer/Metal Hybrid Bonding Applications


Wafer-level hybrid bonding techniques, which provide simultaneous bonding between metal-metal and dielectric-dielectric layers, have attracted more attention in recent years for fabricating 3D integrated circuits with high bandwidth and high interconnect density. However, there are some issues for conventional hybrid bonding using silicon oxide as the dielectric, such as the high stress and low... » read more

Blog Review: Aug. 3


Siemens' Patrick Hope explains the growing importance of choosing the right laminate for PCB designs and how to read a material datasheet to compare important electrical, thermal, and mechanical properties. Synopsys' Yankin Tanurhan argues that as the number of sensors being integrated in automotive systems increases to enable new ADAS and autonomy capabilities, building security and quality... » read more

Scaling, Advanced Packaging, Or Both


Chipmakers are facing a growing number of challenges and tradeoffs at the leading edge, where the cost of process shrinks is already exorbitant and rising. While it's theoretically possible to scale digital logic to 10 angstroms (1nm) and below, the likelihood of a planar SoC being developed at that nodes appears increasingly unlikely. This is hardly shocking in an industry that has heard pr... » read more

Fab Investments Head Toward Record High


Corporations and governments around the globe are making record-breaking investments in chip manufacturing plants amid a major push to make the semiconductor supply chain more robust and less prone to shortages caused by everything from market variations to geopolitical interruptions. These investments — which range from updating existing fabrication facilities to building entirely new fab... » read more

Hybrid Bonding Moves Into The Fast Lane


The industry’s unquenchable thirst for I/O density and faster connections between chips, particularly logic and cache memory, is transforming system designs to include 3D architectures, and hybrid bonding has become an essential component in that equation. Hybrid bonding involves die-to-wafer or wafer-to-wafer connection of copper pads that carry power and signals and the surrounding diele... » read more

Suppressing Stochastic Interaction To Improve EUV Lithography


Authors Zhimin Zhu Sr., Joyce Lowes, Shawn Ye, Zhiqiang Fan, and Tim Limmer of Brewer Science, Inc. (United States) used Stochastic Area Thickness (SAT) and Dynamic Stochastic Area Thickness (DSAT) to evaluate the stochastic interactions. High optical foot exposure is proposed instead of conventional low substrate reflectivity to reduce SAT. Adhesion control by acid/quencher loading is proposed... » read more

5 Tips To Successfully Work Hybrid


Brewer Science is a global company that has international offices and remote employees since I was first hired in 1993. When the pandemic started in 2020, the company easily adapted to a remote/work-from-home structure. We have a company culture that thrives on change, in part due to the innovating and pioneering mindset the company was founded on. These cultural and business practices, combine... » read more

Variation Making Trouble In Advanced Packages


Variation is becoming increasingly problematic as chip designs become more heterogeneous and targeted by application, making it difficult to identify the root cause of problems or predict what can go wrong and when. Concerns about variation traditionally have been confined to the most advanced nodes, where transistor density is highest and where manufacturing processes are still being fine-t... » read more
