Clean Plasma Bevel. Between manufacturing phases, bevel cleaning removes undesired masks, residues, and films from a water’s edge. These materials become flawed if they aren’t cleansed. For instance, during following procedures, they may flake off and re-deposit on the device region.
A difficulty exists in a shop if a fabricator employs a plasma cutting table of some kind and it can cut straight through metal but not bevel. Because modern plasma cutting technology can bevel while the workpiece is on the table, it may surprise you to learn that the time spent beveling is eating into profitability.
The material doesn’t need to be moved to a prep area after that, and an operator doesn’t need to prepare the workpiece for the welder for a while. As a result, the fabrication is finished significantly more quickly. It’s not necessarily a hypothetical situation. While many fabricators continue to use plasma cutting technology, they are losing out on recently discovered efficiencies.
The global plasma-based bevel cleaning system market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.
The production launch of Lam Research Corporation’s brand-new Coronus plasma-based bevel cleaning system was recently announced. The Coronus system combines plasma’s capacity to clean different materials with a patented confinement technology that safeguards the die region in order to prevent yield loss brought on by flaws that start towards the edge of the wafer.
The system, which comes in 200 mm and 300 mm variants, is based on the Lam Research 2300 platform, which has been used in production and has Dynamic Alignment, which creates a reproducible target cleaning area from wafer to wafer and lot to lot. On the top and bottom borders of the wafer separately, the precise cleaning area can be defined. The Coronus bevel clean system is currently entering production with a number of significant semiconductor clients.
“With the launch of the Coronus system, they are using the expertise of a global installed base of more than 1,000 2300 systems as the market leader in plasma etch.
The Coronus customers are able to regulate the wafer edge with the same level of precision and control they require from sophisticated patterning operations in the fab because to the platform’s proven wafer handling accuracy “Vice President of New Businesses at Lam Research.
“Edge faults may now be handled throughout the wafer flow with a single system thanks to the advent of the Coronus system. Employing the Coronus technology for wafer edge cleaning has resulted in significant defect reductions, and customers think that controlling the wafer edge throughout processing will result in fewer defects and higher overall yield.”
