5 Reasons Why Defect Reduction Is Critical In Semiconductor Material Success
By Jessica Albright - 21 Sep, 2023 - Comments: 0

Semiconductors may be small, but the impacts they have are significant. Semiconductors used in life-dependent applications, such as pacemakers, defibrillators, life support systems, automotive safety systems, or in aviation need to be fail-proof. A device smaller than a centimeter with features just a few nanometers has no margin of error. This blog shares why it’s important to detect materia... » read more

Functionalized Carbon Nanotubes Enabled Flexible And Scalable CO2 Sensors
By Brewer Science - 21 Sep, 2023 - Comments: 0

This work, we have demonstrated a low-cost and effective chemiresistive CO2 sensor based on a composite of functionalized carbon nanotubes (f-CNTs) with polyethyleneimine (PEI). The resulting sensor shows excellent selectivity and sensitivity, which can respond to the CO2 concentration in a wide range of 300 - 5000 ppm. The effects of ink dilution and humidity from the environment on the sen... » read more

Chip Industry Week In Review
By The SE Staff - 15 Sep, 2023 - Comments: 0

By Gregory Haley, Jesse Allen, and Liz Allan TSMC told equipment vendors to delay deliveries of the most advanced tools due to uncertain demand, according to Reuters. The news drove down stock prices of all the major equipment providers. On the other hand, TSMC said advanced packaging shortages will constrain AI chip shipments for the next 18 months, according to NikkeiAsia. The United St... » read more

Week In Review: Manufacturing, Test
By Gregory Haley - 01 Sep, 2023 - Comments: 0

Bosch completed its acquisition of TSI Semiconductors to expand its SiC chips business, reports Reuters. In April, Bosch announced plans to invest $1.5 billion in the Roseville, California, foundry to convert TSI’s manufacturing facilities into state-of-the-art processes, with the first SiC chips due out in 2026. Bosch CEO Stefan Hartung said the full expansion "depends on the support of the... » read more

Week In Review: Semiconductor Manufacturing, Test
By Gregory Haley - 18 Aug, 2023 - Comments: 0

Intel dropped out of a $5.4 billion deal to purchase Tower Semiconductor in Israel. Intel cited the inability to obtain regulatory approval in a timely manner as the reason for ending the deal signed in February. Intel will pay a $353 million termination fee to Tower. The silicon wafer supply has moved back into positive territory for 2023 thanks to a 7% decline in wafer shipments combined w... » read more

Directed Self-Assembly Finds Its Footing
By Gregory Haley - 17 Aug, 2023 - Comments: 0

Ten years ago, when the industry was struggling to deliver EUV lithography, directed self-assembly (DSA) roared to the forefront of research and development for virtually every manufacturer determined to extend the limits of 193i. It was the hot topic at of the 2012 SPIE Advanced Lithography Conference, with one attendee from Applied Materials comparing its potential to disrupt the industry to ... » read more

Novel Assist Layers To Enhance EUV Lithography Performance Of Photoresists On Different Substrates
By Brewer Science - 16 Aug, 2023 - Comments: 0

In EUV lithography, good resist patterning requires an assist layer beneath it to provide adhesion to prevent pattern collapse of small features and allow for higher aspect ratios. In addition, future EUV high numerical aperture (NA) is expected to require a decrease in thickness from the overall patterning stack. In this study, we are exploring a fundamentally new approach to developing an alt... » read more

Nine Essential Criteria To Achieve A Successful Bonding Process
By Brewer Science - 14 Aug, 2023 - Comments: 0

A photosensitive permanent bonding material enables the creation of high-quality permanent bonds between dissimilar materials used in the creation of MEMS and sensors. Having a thorough understanding of the materials and product performance is crucial to the success of the end application. In this article, we explore nine criteria used to evaluate a polymeric photosensitive permanent bonding ma... » read more

Battling Over Shrinking Physical Margin In Chips
By Ed Sperling - 31 Jul, 2023 - Comments: 0

Smaller process nodes, coupled with a continual quest to add more features into designs, are forcing chipmakers and systems companies to choose which design and manufacturing groups have access to a shrinking pool of technology margin. In the past margin largely was split between the foundries, which imposed highly restrictive design rules (RDRs) to compensate for uncertainties in new proces... » read more

Goals of Going Green
By Anne Meixner - 25 Jul, 2023 - Comments: 0

The chip industry is stepping up efforts to be seen as environmentally friendly, driven by growing pressure from customers and government regulations. Some manufacturers have been addressing sustainability challenges for more than a decade, but they are becoming more aggressive in their efforts, while others are joining them. A review of sustainability reports across the semiconductor indust... » read more
