Comet, a Swiss company, is the market leader in Plasma Control Technologies (PCT). Plasma, an electrically charged gas often referred to as the “fourth state of matter” (alongside solid, liquid and gas), plays a critical role in advanced microchip manufacturing processes, such as those approaching the 2-nanometre scale. PCT enables the precise shaping and patterning of circuits at such microscopic dimensions.

Comet is also among the top three global players in X-ray systems for advanced semiconductors. The rise of AI has fuelled demand for increasingly powerful chip devices, with modern microchips comprising over 200 layers, each containing hundreds of connection channels as small as 300 micrometres, in what is known as 3D-packaging. Comet’s X-ray systems are purpose-built to inspect and analyse such structures with exceptional clarity and accuracy.

With approximately 80% of its revenue derived from the semiconductor sector, Comet serves leading original equipment manufacturers in the industry, who in turn supply to Tier 1 chip foundries such as TSMC and Samsung.
