 General Static Charge Audit

Find out if your facility has static charge in locations that can be harmful to your manufacturing process. The work includes benchmarking of each step of the production line, measuring electric fields and electromagnetic interference caused by electrostatic discharge.  A report is supplied with interpretation of results and assessment of the magnitude of each item found.

Additionally, this service can also include a search for ESD induced transient EMI. This can be important in facilities with lots of computer-driven robotics or automated testing. This type of EMI can disturb microprocessor operations resulting in locked up  or stopped robots, other robotic unexplained behavior or cause good parts to test bad.

Facility Review

Includes a complete static charge audit and detailed review of each step in the manufacturing process. If you prefer, the study can focus on one part of the manufacturing process, for example photolithography.

Where problems are identified a selection of choices of solutions are recommended.  In addition. The study focuses on identifying the steps required to achieve best practices concerning personnel grounding, garments, equipment grounding, hand tools, chairs, work surfaces and automated handling procedures.  A report is supplied with recommended upgrades to the facility intended to improve facility ESD safety.

Ionizer Performance Verification

Find out if the ionizers in the process are working properly and if they are correctly designed in so that they can achieve the results required,  If the ionizers are in need of maintenance or adjustment you will know it.  If ther ionizers can be made to work better, you will receive recommendations.  If the ionizers used are the wrong type or if additional ionizers are required, the report will include these facts.

Ionizer Service: Clean and Calibrate

Corona ionizers collect material from the environment much like a dust precipitator.  That material lowers the efficiency of the ionizer and must be removed.  Also as tools and fixtures are moved in the cleanroom, the balance of the ionizer is effected.  For both of these reasons and because the control circuitry in the ionizer drifts over time, the ionizers require maintenence.

ESD Training

No ESD control program can succeed without the help and cooperation of the production team.  LBL offers a seminar to teach the people manning your production floor about static charge and how the various steps in a control program work.

ESD Issues for the Senior Manager

LBL understands the complex issues that arise from being in charge of quality management and safety. LBL will work with senior management to consolidate best the practices and drive standardization across the organization.

Specific Problem Solving

Wether you are just starting your ESD control program or static discharge has been a main concern for years, LBL understands that every static problem is unique, ranging from the simple to the incredibly complex.  Contact LBL to discuss any issues, big or small that you may have.

Electrostatics Society of America Presentation

June 9, 2011

The 2011 Annual Meeting of the Electrostatics Society of America will be held June 14-16, 2011, at Case Western Reserve University, Cleveland OH. Papers will be presented in all scientific and technical areas involving electrostatics, and Transforming Technologies is proud to announce that two of our associates work will be included in the event.

On Tuesday, June 14 at 2pm, Dr. Larry Levit of LBL Scientific will be presenting the paper “Generating Air Ionization With No Contaminating Particles”.  Written in conjunction with Doug Buyer of the ESD Company, the session will examine the performance of the Aphaboost technology, a hybrid alpha/electronic air ionizer. Below is the abstract:

Abstract—Modern semiconductor manufacturing employs air ionizers to reduce the effects
of static charge. These effects are contamination control from electrostatic attraction and on
physical damage from discharges. Conventionally, air ionization is generated by corona from
needle electrodes, but there are particles generated by this process. In the past, these particles
have been too small to affect the manufacturing process, but this is no longer true. The latest
small structures on the wafer have reached the limit where these particles will harm the product.
This paper discusses the mechanism for particle creation and presents a design which
creates no particles.

Static Electricity in Cleanrooms: Affects and Remedies

April 21, 2011

The following is an excerpt from the article “Static Electricity in Cleanrooms” by Lawrence B. Levit, Ph.D., founder of LBL Scientific. He has worked in the static charge control industry for over 15 years. Levit is a senior member of the ESD Association, a senior member of the IEST and sits on the Board of Directors of the SiVa ESD Society and is the chair of WG22 of the IEST. He holds 6 patents in the area of ESD control.

Introduction
Static electricity is often overlooked in cleanroom environments and the results of this oversight can cause a reduction in profitability. In some factories where the effects are not studied and understood, they are dealt with by budgeting a reduction in production yield for unforeseen issues. Static charge and its effects certainly can be understood and it can be kept in check. The purpose of this article is to remove the “Black Magic” from the issue, explain how it affects the manufacturing process and discuss remedies

What is special about a cleanroom?
A cleanroon is a unique environment. For many applications it is regulated to a low relative humidity (RH) to optimize the process. Much of the particulate contamination is excluded by massive amounts of air filtration involving high efficiency particulate air (HEPA) filters. Objects in the cleanroom are wiped down before they can enter into the room. As it turns out, these actions are very good for maintaining an ultra clean environment but they are also the prescription for achieving massive levels of static charge in a cleanroom.

It is well known that static charge is created efficiently in a low humidity environment. It is commonplace for individuals to get stung by a spark when they reach for a doorknob in the winter time. Buildings are heated and lower RH results from the temperature rise. This same effect causes the rate of static charge generation to be higher in a cleanroom, especially a low RH cleanroom, than in a conventional room.

Once static charge has been generated by contact with other materials, nature has several methods to dissipate the charge. The first mechanism is conduction of this electrical charge to ground through any surface contamination on the object. Normally, such contamination, for example oil from a person’s hands, is removed from the object before it enters the cleanroom and the object remains clean because the products are only handled by gloved hands.

The only mechanism remaining for the natural dissipation of surface charge is the presence of ions in the air. These ions are created by naturally occurring radioactivity and by other items like runner water and electrical motors. Unfortunately, ions cannot pass through a HEPA filter – they are attracted electrostatically to the materials of the HEPA filter – so they are removed from the air entering the cleanroom.

To complicate matters further, most cleanrooms employ many insulators such as glass and plastic. Teflon, for example, is an incredibly effective insulator and holds onto its static charge aggressively. Glass and other plastics are also very effective insulator. As a consequence of the above argument, cleanrooms allow static charge to be generated very efficiently and dissipated very poorly. The result is levels of static charge which far exceed those in conventional rooms.

Levit graduated from Case Institute of Technology, Cleveland, Ohio with a BS degree in physics with honors.  In 1970, he earned a Ph.D. in Experimental High Energy Physics from Case Western Reserve University. He can guide you to a more profitable factory by eliminating the sources of ESD damage, mitigating microcontamination issues and identifying EMI from ESD that is effecting your robotics and automated test systems.
