Die-level Thinning and Integrating Route For Singulated MPW Chips Using Both Silicon Sensors and CMOS Devices
By Technical Paper Link - 30 Apr, 2022 - Comments: 0

Abstract "Die-level thinning, handling, and integration of singulated dies from multi-project wafers (MPW) are often used in research, early-stage development, and prototyping of flexible devices. There is a high demand for thin silicon devices for several applications, such as flexible electronics. To address this demand, we study a novel post-processing method on two silicon devices, an el... » read more

Expanding Advanced Packaging Production In The U.S.
By Mark LaPedus - 05 Jan, 2022 - Comments: 0

The United States is taking the first steps toward bringing larger-scale IC packaging production capabilities back to the U.S. as supply chain concerns and trade tensions grow. The U.S. is among the leaders in developing packages, especially new and advanced forms of the technology that promise to shake up the semiconductor landscape. And while the U.S. has several packaging vendors, North A... » read more

Scaling Bump Pitches In Advanced Packaging
By Mark LaPedus - 25 Oct, 2021 - Comments: 0

Interconnects for advanced packaging are at a crossroads as an assortment of new package types are pushing further into the mainstream, with some vendors opting to extend the traditional bump approaches while others roll out new ones to replace them. The goal in all cases is to ensure signal integrity between components in IC packages as the volume of data being processed increases. But as d... » read more

System-In-Package Thrives In The Shadows
By Mark LaPedus - 16 Sep, 2021 - Comments: 0

IC packaging continues to play a big role in the development of new electronic products, particularly with system-in-package (SiP), a successful approach that continues to gain momentum — but mostly under the radar because it adds a competitive edge. With a SiP, several chips and other components are integrated into a package, enabling it to function as an electronic system or sub-system. ... » read more

Packaging Technology Needs Of Automotive Radar Sensors Chips
By Ken Hsiao - 22 Jul, 2021 - Comments: 0

Automotive radar systems are typically composed of an antenna, front-end radar sensor and back-end signal processor. Current state-of-the-art automotive radar systems make use of the latest integrated circuit and a wide range of packaging technologies. Let’s look a bit further into the development of automotive radar sensor chips and the packaging technologies being used as solutions for this... » read more

Bumps Vs. Hybrid Bonding For Advanced Packaging
By Mark LaPedus - 23 Jun, 2021 - Comments: 3

Advanced packaging continues to gain steam, but now customers must decide whether to design their next high-end packages using existing interconnect schemes or move to a next-generation, higher-density technology called copper hybrid bonding. The decision is far from simple, and in some cases both technologies may be used. Each technology adds new capabilities in next-generation advanced pac... » read more

Fan-Out Packaging Options Grow
By Mark LaPedus - 17 Jun, 2021 - Comments: 0

Chipmakers, OSATs and R&D organizations are developing the next wave of fan-out packages for a range of applications, but sorting out the new options and finding the right solution is proving to be a challenge. Fan-out is a way to assemble one or more dies in an advanced package, enabling chips with better performance and more I/Os for applications like computing, IoT, networking and sma... » read more

Hunting For Open Defects In Advanced Packages
By Anne Meixner - 17 Mar, 2021 - Comments: 5

Catching all defects in chip packaging is becoming more difficult, requiring a mix of electrical tests, metrology screening, and various types of inspection. And the more critical the application for these chips, the greater the effort and the cost. Latent open defects continue to be the bane of test, quality, and reliability engineering. Open defects in packages occur at the chip-to-substra... » read more
