Samsung to use recycled neon gas in chip manufacturing
Samsung Electronics Co. will use recycled neon gas in chip production for the first time in the world, a move expected to stabilize the cost and supply of the rare noble gas, as well as lower the company's carbon footprint.

According to sources in the semiconductor industry, the world's largest memory chip producer has successfully used recycled neon gas in chip mass production without degrading chip quality. Encouraged by the result, the South Korean chip giant plans to use recycled neon gas in chip manufacturing from next year in what would be the world's first of its kind.
Neon gas is a rare noble gas that is also an essential raw material in the photolithography process. It is used to generate laser light to transfer a circuit pattern on a substrate, and it is also widely used in not only the semiconductor industry but also other areas such as the display sector.
Samsung Electronics has relied solely on imported neon gas, mainly sourced from Ukraine, Russia and China.
But since the outbreak of the Russia-Ukraine war in 2022, its price has skyrocketed due to a supply shortage. Its import price even soared to $1,612 per liter in 2022 from $58 in 2021.
The shockingly inflated price led Samsung Electronics to seek out supply alternatives, including the recovery of the rare noble gas from laser waste streams.
