Why Wafer Bumps Are Suddenly So Important

Wafer bumps need to be uniform in height to facilitate subsequent manufacturing steps, but a push for 100% inspection in packaging in mission-critical markets is putting a strain on existing measurement technologies.

Chiplets: A Short History 

In another “rabbit hole moment,” I lost myself in a bout of reminiscence on the Internet Archive’s Wayback Machine. A prehistoric SemiSerious blog post from 2009 attempted to provide updates from ISSCC 2009. TechInsights engineers Aaron Murray, James Bull, and Mohammad Ahmad provided the boots on the ground reports to HQ. I believe these three fine gentlemen all continue their yeoman’s work at the Ottawa company.

Momentum Builds For Advanced Packaging

The semiconductor industry is stepping up its efforts in advanced packaging, an approach that is becoming more widespread with new and complex chip designs.Foundries, OSATs and others are rolling out the next wave of advanced packaging technologies, such as 2.5D/3D, chiplets and fan-out, and they are developing more exotic packaging technologies that promise to improve performance, reduce power, and improve time to market. Each package type is different, with various tradeoffs. As before, the idea behind advanced packaging is to assemble complex dies in a package, creating a system-level design. But advanced packaging faces some technical and cost challenges.

Survey in 3D Electronics Alternative to PCBs 

Mention an electronic circuit and you are likely to picture a printed circuit board (PCB): a rigid rectangle in a characteristic green color with copper lines and a bewildering array of components soldered onto it. But does adding electronic functionality means using a PCB and thus requires shoehorning a rigid rectangle into the product?

Choosing Between 2D and 3D Materials for Next-Gen Semiconductors 

Researchers at Pohang University of Science and Technology (POSTECH) exploit resistive switching property in halide perovskite materials to develop the basis for a new type of fast, low-power, nonvolatile memory. Halide perovskite materials exhibit a resistive switching property, which means that with the application of a voltage, the substance’s resistance will change.

Next Challenge: Known Good Systems

The leading edge of design is heading toward multi-die/multi-chiplet architectures, and an increasing number of mainstream designs likely will follow as processing moves closer to the edge.This doesn’t mean every chipmaker will be designing leading-edge chips, of course. But more devices will have at least some leading-edge logic or will be connected over some advanced interconnect scheme to one or more of those leading-edge chips or chiplets. The challenge will be verifying and debugging all of these devices in the context of how they will be used, and then testing them repeatedly in the lab, in manufacturing, during and after packaging, and for as long as they are used in the field.
