MegPie Transducer (100/150mm) Dual Zone  - Stainless Steel

The Dual Zone MegPie is a single-wafer Megasonic transducer for cleaning and sonochemical
processing of multiple substrate sizes in one chamber. It applies a uniform dose of acoustic energy to a
rotating substrate. The MegPie will improve your process efficiency and lower the process time. It is easy
to retrofit to your single substrate processing tool.

Material: Stainless Steel
Processes two sizes of substrates: 150 / 200 mm, 200 / 300 mm, or 300 / 450 mm
