Cleanroom Air Process Automation and Control is a $353 Million Market

There is a large opportunity to reduce product failure and energy consumption in clearnooms through more complete automation of processes and control of the air handling systems.  In 2013, cleanroom operators will spend $353 million for automation and control solutions for the air handling systems. This is the latest forecast in the McIlvaine report, World Cleanroom Markets.  (www.mcilvainecompany.com)

($ Millions)

The revenues include advanced process control software, distributed control systems, programmable logic controllers and instrumentation to measure air flow, pressure and temperature.

The semiconductor industry market will be equaled by a group of other electronics segments including flat panel displays and memory storage.  The pharmaceutical industry is also a significant segment. The hospital segment is limited to the laboratories and special operating rooms which maintain high purity cleanroom environments.

In general, air handling systems in cleanrooms must control the vertical downward air flow. Temperature control is much more important than in typical manufacturing. A slight positive pressure is also required to ensure that no unclean air enters through any room openings.

More sophisticated systems can save energy by controlling and varying air flow to meet the cleanroom needs. It has been learned that the cleanliness of a room is a function of the number of people in the room and the movement of those people. With the use of variable speed fan drives and facility particle monitoring systems with multiple monitors, it is possible to reduce air flow when air cleanliness exceeds the needs. This can result in large energy savings.

This task is complicated in certain applications such as semiconductor manufacture by the need to control gaseous contaminants such as ammonia.  There are now continuous ammonia monitors which can also be integrated into the control system.

The use of mini environments dictates the use of more complex automation systems. There is the need to control the air purity within the mini environments and also in the larger clearnoom where the mini environments reside.

One of the challenges for control has been the increasing popularity of the Fan Filter Unit (FFU).  The ceiling of the cleanroom is fitted with small packages containing a filter and fan. There can be hundreds of these units in one ceiling. The advantage is flexibility and more even distribution. This requires a control system which must deal with each of the FFUs.  An FFU interface can be as simple as manual controls to sophisticated stand-alone systems or even interfaces that will tie into building management central control rooms. With smart FFU products being more readily available, the utilization of these units in “smart systems” is the logical progression.

Low initial investment costs along with an equally low cost of system expansion make the distributed system both flexible and cost-effective.

Another function of the control system can be to alert operators as to when to change filters. Differential pressure sensors monitor the status of clean room air filters. Pressure ports are connected to either side of the filter; as the filter becomes clogged, the difference in pressure between the two sides increases. The differential pressure sensor is programmed to detect the point at which the pressure difference indicates the time for filter replacement, and when it is reached, the sensor triggers an output alarm.

Online Control of Moisture and Integrated Data Management Capability will be Explained by Yokogawa

Yokogawa will display PAT solution regarding online quality monitoring, quality data management to support RTRt (Real Time Release testing), and will demonstrate prototype products.

Thermo Fisher will be an Exhibitor and will be Making a Number of Presentations:

Monitoring Temperature in Semiconductor Cleanrooms is Critical

In semiconductor manufacturing processes, a deficient clean room environment can lead to defects and wasted resources, making a strictly controlled clean room indispensable. Maintaining the environment in the clean room requires control of air filters, HVAC systems, room temperature, humidity, airborne particles, and other factors.

For remote monitoring applications, the Yokogawa MW100 offers a full set of features that let the operator access data instantly by entering a unit’s URL into a Web browser. And, in addition to being able to acquire data files remotely, an e-mail function can be used for notification of abnormalities.

Monitoring and Recording of Information on Production Equipment inside Cleanrooms is Best Done Digitally

In food and beverage plants, monitoring and recording of production equipment is necessary inside clean rooms. Two important needs are:

·         Eliminate chart paper inside the cleanroom

·         Easy method for writing messages on the recorded data

The Yokogowa  DX1000T/DX2000T Paperless Recorder Touch Screen Model delivers all-digital data recording. It also provides for message input with custom displays^*1 and the touch panel. The following display shows options for trends, bar graphs and screen shots.

Facility Air Particle Counter Data Displayed and Recorded

Air particle counters are used for air climate control monitoring in semiconductor and medical cleanrooms.
DXAdvanced can acquire the cleanliness factor data measured by the particle counter via communication, and display and record it without degradation of accuracy.

In the figure above, a particle counter acting as the Modbus slave is connected via RS-485, then data such as the cleanliness factor of 2 grain diameters (0.5 μ m/5.0 μm), sample flow rate, and CAL (measurement status) are displayed and recorded on DXAdvanced via Modbus/RTU communication.

• DXAdvanced and the particle counter are connected via Modbus/RTU (RS-485)
  /C3 = RS-422A/485 communication interface option
• Numeric display/recording on MATH CH
  /M1 = computation function option
• Alarm relay output on abnormal cleanliness factor
  /A1 = alarm output relay option

Up to 16 DXAdvanced master commands can be set.
(The number that can be connected varies depending on the number of data acquired from the counter and the register configuration.)

Ammonia Monitoring by Chemiluminescene in Cleanrooms

The Horiba TG-520 and CU-2 Ambient ammonia analyzer in Semiconductor clean rooms measures differential concentration between ambient nitrogen oxide and increased nitrogen oxide after oxidation catalyst reaction as ammonia concentration directly with cross-flow modulation type chemiluminescence method with 10ppb at min. detectable sensitivity

CM501 Clean Room Gas Monitor from Yokogawa uses Ion Chromotography

The CM501 clean room gas monitor measures ammonia and acid gases continuously at high sensitivity by utilizing a diffusion scrubber and an ion chromatograph. Diffusion scrubber is to absorb ammonia/acid gases in pure water. Then these are analyzed with an ion chromatograph.

Sierra Monitors Ammonia and Hazardous Gases in Semiconductor Plants but not at the Sensitivity Required inside the Cleanroom Space

There are major differences in the requirements to measure ammonia and other gases inside the semiconductor cleanoom and in the ambient space. One requires continuous ppb measurement and the other a simple alarm when the quantity exceeds 50 ppm.

The manufacturing of Semiconductors and other high technology devices usually entails the use of various hazardous and combustible gases including Silane, Hydrogen, and others. Sierra Monitor’s Sentry Gas Detection System includes sensors for many toxic gases used in the industry. In addition Sierra Monitor’s gas alarm monitors, including the CM980411 for Hydrides (including Silane) and CM99-447 for Ammonia are used in the Semiconductor manufacturing industry to monitor for these specialty gases.

The Ammonia and Hydride Gas Monitor is a continuous duty, low cost stationary monitor for detection for Hydride or Ammonia gas. The monitor has a green LED indicating the unit is on and in a safe condition. A red LED will light when the unit is in alarm. The 1 amp relay will activate when the gas concentration exceeds 5 ppm Silane or 50 ppm Ammonia. This relay is latching which means that the relay will stay activated until it is reset with the switch on the side of the monitor.

The monitor is an aluminum enclosure that is suitable for most applications. Test connections and adjustment controls are located on the outside of the enclosure and are easily accessible.

The CM98-411 is designed to monitor for Silane in the range of 1-50 ppm with an alarm setpoint at 5 ppm Silane.

The CM99-447 is designed to monitor for Ammonia in the range of 1-200 ppm with an alarm setpoint at 50 ppm Ammonia. The alarm used in this unit is an electrochemical gas sensor.

Fire is always a danger in Semiconductor clean rooms where the equipment houses a variety of flammable materials and liquids including IsoPropyl Alcohol. The Model 3200 Flame Detector is specially designed for these Wet Bench applications to constantly monitor for flames that could lead to a catastrophe in the clean room.

Bringing the data from the various sensors, devices and systems in a semiconductor plant to the central processing system is important in the safety, efficiency and operation of the semiconductor manufacturing facility. The FieldServer gateway is important in this situation since the extensive FieldServer driver library has a wide range of protocols used in this industry including Modbus, LonWorks, ControlNet and Profibus

Kanomax Supplies Precision Instruments for Cleanrooms

Kanomax group has its origins in Kano Laboratory established by Goro Kano who was the founder of Kanomax Japan, Inc. incorporated back in 1951. For the past 60 years, Kanomax has been continuously growing due to its engineering in fluid, aerosol/particle, environmental and integrated system measurement technologies.

By the 1970's Kanomax had become a leading manufacturer of anemometers and particle measuring instruments in Japan.

Kanomax has recently launched its global operations to further provide the best measurement solutions available in the mark.

During the technology boom, the semiconductor and HDD industries were the biggest users of cleanrooms and, in a stable way, they still remain one of the most important users. However, as the world of science rapidly progresses, the demand for cleanrooms from players especially in the bio-tech and pharmaceutical markets have become noticeably strong. The cleanroom class level of bio-techs and pharmaceuticals (typically around Class 5) is still less stringent than those of semiconductor cleanrooms (an extreme and rare example is a Subclass 0.1 cleanroom at the semiconductor R&D level). Nonetheless, only a small handful of precision measurement manufacturers have the genuine capabilities as Kanomax to satisfy their monitoring and measurement needs.
