Hybrid Bonding Makes Strides Toward Manufacturability


Hybrid bonding is gaining traction in advanced packaging because it offers the shortest vertical connection between dies of similar or different functionalities, as well as better thermal, electrical and reliability results. Advantages include interconnect scaling to submicron pitches, high bandwidth, enhanced power efficiency, and better scaling relative to solder ball connections. But whil... » 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

Week In Review: Manufacturing, Test


Fab tool shipping costs The coronavirus is impacting semiconductor equipment companies. Many have withdrawn their previous forecasts. “It has also led to a rise in shipping costs,” said Krish Sankar, an analyst with Cowen, in a research note. Most semiconductor equipment and components are shipped via air, according to Sankar. The exception is flat-panel display equipment and other sys... » read more

Lithography Challenges For Fan-out


Higher density fan-out packages are moving toward more complex structures with finer routing layers, all of which requires more capable lithography equipment and other tools. The latest high-density fan-out packages are migrating toward the 1µm line/space barrier and beyond, which is considered a milestone in the industry. At these critical dimensions (CDs), fan-outs will provide better per... » read more

Litho Options For Panel Fan-out


Several packaging houses are inching closer to production of panel-level fan-out packaging, a next-generation technology that promises to reduce the cost of today’s fan-out packages. In fact, ASE, Nepes, Samsung and others already have installed the equipment in their panel-level fan-out lines with production slated for 2018 or so. But behind the scenes, panel-level packaging houses contin... » read more

Inside Panel-Level Fan-Out Technology


Semiconductor Engineering sat down to discuss panel-level fan-out packaging technology with Tanja Braun, deputy group manager at the Fraunhofer Institute for Reliability and Microintegration IZM, and Michael Töpper, business development manager at Fraunhofer IZM. Braun is responsible for the Panel Level Packaging Consortium at Fraunhofer IZM, as well as the group manager for assembly and encap... » read more
