Aalto University in Finland Wins Major Grant for Eco-Friendly Semiconductor Technology

Aalto University, in close collaboration with key industry players including Applied Materials in Finland (Picosun), PiBond, and Volatec, has been awarded a significant grant by Business Finland for their groundbreaking project titled “New chemistries for resource-efficient semiconductor manufacturing”. This initiative is a part of the larger "Chip Zero" Ecosystem, spearheaded by Picosun, aiming to revolutionize the semiconductor industry by developing chips that boast zero lifetime emissions—a first in Finland's tech landscape.

Led by Professors Maarit Karppinen and Antti Karttunen from Aalto's Department of Chemistry and Materials Science, the project seeks to address the pressing environmental concerns associated with semiconductor manufacturing. With the industry's carbon footprint and resource consumption at an all-time high, this co-innovation venture promises to pave the way for more sustainable production methods.

The project's goals are ambitious yet crucial. By innovating new chemical processes and materials, the team aims to minimize the environmental impact of semiconductor fabrication. This includes the development of novel, eco-friendly precursors and solvents, enhancing material purification, and advancing recycling practices, as highlighted by Dr. Marja Tiitta from Volatec.

Dr. Thomas Gädda of PiBond emphasizes the importance of collaborative efforts in achieving these sustainability targets, underscoring the project's reliance on a synergy of expertise from academia and industry. This collaborative framework is expected to yield advancements in chemical usage, process optimization, and energy efficiency in semiconductor manufacturing.

With its comprehensive approach, combining experimental research with computational modeling, the project aspires not only to innovate within the confines of semiconductor technology but also to set a new standard for environmentally conscious manufacturing practices in the industry.

Imec´s sustainable-semiconductor program is a success right away!

Imec´s sustainable-semiconductor program (LINK) seems to be a success right away:
  • Less than a year after its official launch, some of the leading consumer electronics and semiconductor manufacturing players have signed up as partners in imec’s program for Sustainable Semiconductor Technologies and Systems (SSTS).
  • Apple joined the program Apple joins Imec's new Sustainable Semiconductor research program | iMore
  • The program assesses the environmental impact of new technologies, identifies high-impact problems, and defines semiconductor manufacturing solutions with less environmental impact.
  • In this way, the program gathers the semiconductor value chain to jointly target net-zero emissions for chip manufacturing.
  • One good reason for success is most probably that Lars-Åke Ragnarsson from Sweden is the program director of sustainable semiconductor technologies and systems (SSTS) at imec.

Samsung to focus on treatment of gas used in chip production to achieve net-zero emissions

A major cause of greenhouse gas emissions is process gas used in semiconductor wafer manufacturing comes from processing equipment such as reactive ion etching (RIE) and deposition (CVD and ALD). You can read and watch an interview here and study that paper that was recently published by me and my professor friends Henrik Pedersen and Sean Barry:


Green CVD-Toward a sustainable philosophy for thin film deposition by chemical vapor deposition

It is almost obvious that higher VPs at Samsung and TSMC (LINK) did just that ;-)

[Korea Herald, Link below] Advancing abatement technologies to reduce carbon emissions is the top priority in the Samsung Electronics semiconductor unit's goal to become carbon neutral by 2050, a top official said Friday.

"Treatment of gas used to manufacture semiconductor chips is our biggest focus in our spending (to achieve net-zero emissions)," Song Doo-guen, executive vice president and head of the Environment & Safety Center at Samsung Electronics, told reporters at a briefing in Seoul.


According to the article, Song Doo-guen, executive vice president and head of the Environment & Safety Center at Samsung Electronics, speaks at a briefing in Seoul, Friday and announced that:
  • Samsung has pledged a 7 trillion won ($5 billion) investment to achieve its climate ambitions, and announced that it had recently joined RE100, a coalition comprising 380 global enterprises committed to becoming 100 percent renewable.
  • Alongside the plan to cut direct carbon emissions, Samsung has also laid out a raft of plans to reduce indirect emissions, mainly by pursuing ultralow-power chip products.
  • Other eco-conscious plans it has drawn up include capping the maximum use of freshwater to 300,000 tons a day by 2030 and eradicating gaseous and liquid pollutants by 2040 with treatment technology.
