How Megasonic Cleaning Works

Megasonic cleaning removes sub-micron particles from wafers and substrates using high-frequency acoustic energy transmitted through a cleaning liquid, typically SC1 or a similar chemistry. A transducer sends rapid pressure waves and acoustic streaming across the wafer surface, and that motion dislodges particles too small or too strongly bound for chemistry alone to remove. Because the frequency is much higher than conventional ultrasonic cleaning, the energy is gentle enough for delicate device features while still clearing contamination down to 0.1 micron, where aggressive ultrasonic cavitation would risk damage.
Modutek builds megasonic cleaning equipment in two configurations. The indirect MSI Series uses a bath design that removes 0.1-micron particles and operates at temperatures up to 140°C. The Direct MSD Series places a Teflon-coated megasonic transducer plate directly in the tank, making it well-suited for quick installation or upgrades to an existing bath and ideal for SC1 applications, with a maximum temperature rating of 70°C. In either case, Modutek’s engineers design, build, and test each system in-house at the San Jose, California, facility and configure it to your cleaning chemistry, particle target, and temperature requirements.

Megasonic Cleaning Equipment FAQs

1.What Is the Difference Between Megasonic and Ultrasonic Cleaning?
Ultrasonic cleaning uses lower frequencies that produce strong cavitation, which cleans aggressively but can damage fine features. Megasonic cleaning uses much higher frequencies (from 950 kHz to 3 MHz) that generate gentler pressure waves and acoustic streaming, thereby removing sub-micron particles while protecting delicate device structures. This makes megasonic the preferred method for advanced wafer and substrate cleaning.
2. What Is the Difference Between the MSI and MSD Series?
The MSI Series is an indirect bath design that removes 0.1-micron particles and operates at temperatures up to 140°C. The MSD Series is a direct design with a Teflon-coated transducer plate mounted inside the tank, rated up to 70°C and ideal for SC1 applications. The MSD configuration is particularly suited to upgrading an existing bath because the transducer installs directly into the tank.
3.What Particle Sizes Can Megasonic Cleaning Remove?
Modutek megasonic systems remove particles down to 0.1 micron. Because acoustic energy acts on particles that chemistry alone cannot lift, megasonic cleaning is used where sub-micron particle counts must meet strict limits, such as pre-diffusion, post-CMP, and SC1 cleaning steps.
4.Can Megasonic Cleaning Be Added to an Existing Wet Bench?
Yes. The Direct MSD Series places its Teflon-coated transducer plate directly in the tank, allowing it to be installed in an existing bath as an upgrade rather than requiring a new system. This allows a facility to add megasonic particle removal to its current wet processing equipment with minimal disruption.
5. What Industries Use Megasonic Cleaning Equipment?
Megasonic cleaning is used in the semiconductor, flat panel display, hard disk, solar, and crystal industries. These applications all require the removal of sub-micron particles from sensitive surfaces, and megasonic energy provides the cleaning needed to avoid damaging fine features or thin films.
