Megasonic Cleaning Systems Overview

Megasonic Technology Uniformity Test

The use of megasonic technology has been shown to be an essential performance element in advanced cleaning applications. Combining over 40 years of industry know-how with some of the most reliable megasonic components available, Imtec has designed a cleaning system for a wide-range of high-purity processes. The Accumeg is designed to provide continuous megasonic energy across the full width and depth of all the substrates in the process tank. This constant energy is the key to complete, fast, efficient cleaning and the elimination of particle reattachment.

Unlike other systems, which use "pulsed" megasonic transducer arrays in an attempt to achieve even, full coverage, the Accumeg megasonic transducer array covers the entire process load capacity of the tank without any of the energy loss associated with "shadowing" or "sequencing".

Backed by our extensive 36 month warranty, Imtec's Accumeg series offers the reliability and productivity that ensures excellent uptime, minimum maintenance and the lowest cost of ownership.

Megasonic Energy Uniformity Test with Probe & Robotics

"Gapless" Transducer - For better process uniformity in the tank, the piezoelectric crystals on the transducer should be installed as close together as possible. However, when each crystal is wired to the generator individually, they must be spaced at least 1mm apart to avoid arcing that shorts out the transducer.

Imtec uses superior transducers with tightly matched crystals wired together in parallel. This means that there is a small potential difference between crystals and they can be placed close together- 0.1mm apart- without risk of shorting.

Megasonic Quick Dump Rinse Bath (QDR)- To quickly remove chemical and particulate from a bath after a process run, Imtec developed and patented the QDR Accumeg. Rather than disturbing the bottom of the bath where the transducer is mounted, the Imtec system raises the walls of the bath, allowing the chemical to flow out evenly and rapidly, and without allowing any particulate settled at the bottom of the bath to re-attach to the substrate. This "tank lift" system maintains a clean environment and saves valuable processing time.
