Neon Gas in Chip Manufacturing:

Neon gas plays a crucial role in semiconductor manufacturing, particularly in the lithography process.

It is utilized in excimer lasers or ultraviolet lasers, essential for carving intricate patterns onto silicon wafers.

However, the reliance on imported neon gas has posed challenges for chipmakers, especially amidst geopolitical tensions and supply chain disruptions.

The Need for Recycling Technology:

With the global supply of neon gas affected by factors such as the Russia-Ukraine conflict, semiconductor manufacturers have sought alternative solutions to mitigate supply chain risks and reduce dependency on imports.

There are two main reasons why neon gas recycling technology is important:

Stable Supply and Cost Reduction: Neon is crucial for chip manufacturing, but a large portion of it comes from a few countries like Ukraine . This creates a situation where disruptions like the Russia-Ukraine conflict can cause price spikes and supply chain issues. Recycling allows chipmakers to reuse the neon they already have, reducing their reliance on external suppliers and potentially stabilizing costs.

Environmental Benefits: Extracting and purifying neon gas can be energy-intensive. Recycling significantly reduces the need for this process, leading to lower greenhouse gas emissions. Estimates suggest a reduction of up to 95% in carbon emissions compared to producing new neon gas.

    So, neon gas recycling offers a win-win for chipmakers – it helps them become less reliant on external factors for a key material and also contributes to a more sustainable manufacturing process.

    Recycling technology emerges as a viable option, offering both economic and environmental benefits.

    SK Hynix and TEMC’s Innovation:

    Over the course of a year-long collaboration, SK Hynix and TEMC have developed a sophisticated neon gas recycling process.

    This process involves the collection of discharged neon gas through a scrubber, such as followed by purification and treatment to extract reusable neon gas.

    This technology is a big deal because it can potentially:

    • Reduce Reliance on Imports: Currently, chipmakers rely heavily on imported neon gas. Recycling can lessen this dependence.
    • Boost Sustainability: Recycling neon gas reduces greenhouse gas emissions, making chip production more sustainable.

    Overall, SK Hynix’s innovation paves the way for a more cost-effective and eco-friendly semiconductor industry.

    By implementing this technology, SK Hynix anticipates significant cost savings, reducing its annual expenditure on neon gas imports by an estimated $30 million.
