Four Things Every Engineer Should Know About PFAS


What are PFAS chemicals? “PFAS” is an acronym for per- and polyfluoroalkyl substances. These man-made chemicals migrate into soil, water, and air when produced and used. There are many ways humans come in contact with PFAS, such as in non-stick cookware or cosmetics, but by far the most significant impact on human health is when PFAS is consumed in drinking water. Exposure to PFAS may resu... » read more

The Rise Of Thin Wafer Processing


The shift from planar SoCs to 3D-ICs and advanced packages requires much thinner wafers in order to improve performance and reduce power, reducing the distance that signals need to travel and the amount of energy needed to drive them. Markets calling for ultrathin wafers are growing. The combined thickness of an HBM module with 12 DRAM dies and a base logic chip is still less than that of a ... » read more

Many Options For EUV Photoresists, No Clear Winner


In EUV lithography, and especially high-numerical-aperture EUV, balancing tradeoffs between resolution, sensitivity and line-width roughness is becoming increasingly difficult. Lithography patterning using extreme UV exposure depends on a resist mask that can simultaneously meet targets of small feature resolution, high sensitivity to EUV wavelength, and acceptable linewidth roughness. Unfor... » read more

Chip Industry Week In Review


Intel said its new fab in Licking County, Ohio will be delayed due to financial struggles and a need to align chip production with market demand, reported the Columbus Dispatch. Construction is now estimated to be completed in 2030, with operations to start in 2030 or 2031. The company said it already has invested $3.7 billion locally. Apple plans to invest more than $500 billion in the U.S... » read more

Chip Industry Week In Review


The EU Commission approved €920 million in German State aid to support Infineon in setting up its Smart Power Fab in Dresden. Total funding for the Dresden site amounts to about €1 billion. PDF Solutions will acquire secureWISE for $130 million to expand the reach of its semiconductor manufacturing data platform, providing secure, remote access monitoring and control. Tariffs, trade, and ... » read more

Back-End Packaging And Test: From Lessons Learned To Future Innovations


The semiconductor industry is a hallmark of technological innovation, evolving rapidly to meet the demands of an increasingly digital world. At its core, semiconductor manufacturing involves two main stages: front-end processes, (wafer fabrication) and back-end processes (packaging and test). Wafer fabrication consists of creating microscopic electronic circuits on a silicon wafer. Packaging an... » read more

EUV’s Future Looks Even Brighter


The rapidly increasing demand for advanced-node chips to support everything-AI is putting pressure on the industry's ability to meet demand. The need for cutting-edge semiconductors is accelerating in applications ranging from hyperscale data centers powering large language models to edge AI in smartphones, IoT devices, and autonomous systems. But manufacturing those chips relies heavily on ... » read more

Electrifying Everything: Power Moves Toward ICs


As electronic systems grow increasingly complex and energy-intensive, traditional power management methods — centered on centralized systems and external components — are proving inadequate. The next wave of innovation is to bring power control closer to the action — directly on the chip or into a heterogeneous package. This change is driven by a relentless pursuit of efficiency, scala... » read more

Upcoming Challenges And Changes In Semiconductor Materials


Semiconductor Engineering sat down with Dan Brewer and Srikanth Kommu, co-CEOs at Brewer Science, to talk about current and future changes in materials used in semiconductor manufacturing and adjacent markets. What follows are excerpts of that conversation. SE: What was behind the decision to have co-CEOs instead of just one? Brewer: We see a lot of value to having multiple perspectives b... » read more

Baby Steps Toward 3D DRAM


Flash memory has made incredible capacity strides thanks to monolithic 3D processing enabled by the stacking of more than 200 layers, which is on its way to 1.000 layers in future generations.[1] But the equally important DRAM has achieved a similar manufacturable 3D architecture. The need for a sufficiently large means of storing charge — such as a capacitor — has proved elusive. Severa... » read more
