How Acid Fume Scrubbers Work to Maintain a Clean Work Environment

Creating silicon wafer microstructures, integrated circuits, and processors require an extensive multi-step process that consists of etching, stripping and cleaning silicon wafers.

Chemicals like sulfuric acid, hydrochloric acid, and hydrogen peroxide can carry out these operations effectively but they give off vapor and fumes that can be harmful to workers inside and outside the workspace. There are also regulatory compliances issues for a safe working environment and for emissions to the outside environment. Acidic vapors coming from the wet process stations consist of tiny droplets, which can be extremely corrosive and can negatively impact the health of workers when inhaled. This requires the use of acid fume scrubbers which remove harmful vapors from the air to leave a clean workspace and clean air that can be discharged outside the manufacturing facility. Modutek provides acid fume scrubbers that have a high level of efficiency and low cost of operation as well.

How do Modutek’s acid fume scrubbers work to keep the work environment free of these harmful vapors? They neutralize the acid vapors and clean the exhaust air so that it is no longer dangerous for workers or harmful for the environment. The exhaust air containing the acid vapors is first passed over a bed of wet packing material, which has a special liquid that includes a chemical that safely neutralizes the acid. The acidic mist passes over the wet packing bed, where the acid is neutralized and absorbed from the exhaust air. The air that goes out of the scrubbers contains only faint traces of acid that is safe to discharge in the air.

The effectiveness of the scrubbers depends on the volume of air the scrubbers must “clean” as well as the surface area of the wet packing. Modutek’s high-efficiency acid fume scrubbers can help keep your work environment clean and healthy.

How Customized Equipment Has Improved the Silicon Wafer Cleaning Process

Specific customer requirements or unusual process characteristics may require the use of customized systems or components. In order to support these kinds of projects, suppliers must have extensive in-house expertise as well as a broad range the silicon wafer cleaning equipment to offer custom solutions.

Modutek has extensive in-house expertise and provides a full line of silicon wafer cleaning equipment to meet customer needs. This can improve throughput, lower costs, and result in higher output quality and yield.

Modutek's SolidWorks Simulation Professional and SolidWorks Flow Simulation software allow customers to calculate precise chemical doses as well as monitor on chemical usage. Modutek writes and develops their own software so that the company can make the necessary adjustments and implement software customization whenever the client requires it.

This means that the client can use software that is modified to their own customized systems rather than trying to operate a custom system with standard software. The great thing about Modutek's software is that it can be tailored to make accurate control and monitoring even for the most customized installations.

There are several types of custom-fit equipment that is incorporated within a wafer cleaning installation. These can include the following:

·         Megasonic Systems

·         Quartz Baths

·         Teflon tanks

·         Other custom equipment

Modutek can also provide customized versions of these components to fit any new or existing wet process system to optimize the silicon wafer cleaning process.

Modutek also develops custom wet bench designs based on the certain process specifications – the software, the chemical delivery system, baths a, d wafer handling. They need to all fit together to satisfy the process requirements.

The silicon wafer cleaning processes can be also customized at the component or system level, but they can also feature customized levels of automation. There is the standard manual, semi-automatic and fully automatic systems but there is also a possibility of “special” systems, e.g., customers may want a manual system but at the same time, they also want certain process sub-steps to be run automatically.
