Semiconductor Device Fabrication

A Semiconductor Device Fabrication Cleanroom is a clean air environment and has the function of preventing air particulates of a certain size from entering. Cleanrooms are required by many industries like food production, E-liquids, science and technology, pharmaceuticals, and healthcare facilities among others to minimise pollution from unfiltered air.

The types of impurities that are kept out of the cleanroom through filtering include airborne microbes, dust, chemical vapours, and aerosol particles among others. We build Semiconductor Device Fabrication Modular Cleanrooms that are compliant to the international organisation for standardisation (ISO) 14644-1: 2015.

The ISO 14644-1:2015 compliant Semiconductor Device Fabrication Modular Cleanrooms vary between class 1 and 9. Each Cleanroom is classed according to the maintained level and size of air particulates in the environment. The Class 1 classification is the greatest in the range and it is tested for the lowest frequency and smallest particulate size while the Class 9 classification represents the least in the range and is valued based on a higher frequency and larger air pollutants present in the cleanroom at any given time.

The use of particle counters is employed to test Semiconductor Device Fabrication Modular Cleanrooms for classification where the environment is measured by Particles Per Cubic Metre (PPCMM). The Particles Per Cubic Metre of an (ISO) 14644-1: 2015 Class 9 Modular Cleanroom corresponds to normal atmospheric air with contaminants >5 microns not allowed into the environment.

A Class 1 Cleanroom will focus on much smaller air particulates of sizes >0.1 microns and >0.2 microns resulting in a much cleaner air enclosure. The following is an example of the testing method.

A Modular Cleanroom that falls in Class 7 will be tested for the presence of an air particulate size of >0.5 microns where the highest particle count should be capped at 352,000. Failing to maintain the required particle size and count, the Semiconductor Device Fabrication Cleanroom will have to go through modifications and re-evaluation in order to meet the classification.

Pollution-free production

The amount and sizes of air particulates maintained in Semiconductor Device Fabrication Modular Cleanrooms are achieved through the use of HEPA/ULPA filtering technology. These technologies have undergone research evaluations to prove that they effectively reduce the quantity and size of air contaminants entering a cleanroom. When non-filtered air goes through Filter Fan Units (FFUs), a positive pressure area is introduced and maintained in the clean air environment. Contamination is controlled in the clean air environment by means of the positive pressure as it prevents non-filtered air from flowing back into the cleanroom through exhaust openings.

Pollution-free manufacturing is fostered through the mechanism of the aforementioned type of Semiconductor Device Fabrication cleanroom as it only allows the air that passes through the filtration unit to enter the internal space.

Modular Cleanroom Benefits

  • Modular Construction
  • Quick Assembly Time
  • Versatility
  • Reconfiguration
  • Airflow Control
  • Inexpensive Modifications

The Semiconductor Device Fabrication Cleanroom mechanism will mitigate the possibility of product contamination. It’s also the first stage of putting a clean air production area in place. The second steps to take in reducing contamination are preventative measures for the introduction of air particulates caused by personnel working in the cleanroom. Cleanroom clothing like gowning, hair nets, and overshoes can go a long way in helping to avoid the introduction of pollutants by personnel. This will aid in decreasing microbes and other contaminants from infiltrating the clean air space and intruding the research/production process. Personnel has to be taught pollution reduction techniques that will ensure required levels of contaminants in the cleanroom are maintained.

Industry demands

In order to produce non-polluted products, certain industries require clean air environments that see to the reduction of particulates in the production area.

With the use of air filtration, Cleanrooms provide a much-needed reduction of particulates in the production area. Cleanrooms are used in the production of medical devices, semiconductors, food products, electronics and a lot more.

At TCA, our main goal is to see to it that you’re provided with the right solution for your needs. You can be guided by our experts if you’re entirely sure of the standard of Semiconductor Device Fabrication Cleanroom your industry requires.

Our Semiconductor Device Fabrication Modular Cleanrooms are constructed to meet the standards of the ISO 14644-1: 2015. These Semiconductor Device Fabrication Modular Cleanrooms are differentiated according to classes – ISO 1-9. The size and quantity of air particulates in a Cleanroom will determine the class it belongs to. A Cleanroom with the highest classification (class 1) will be tested for the smallest particulate sizes whereas the lowest classified Cleanroom (Class 9) will have a much larger size and a greater quantity of air particulates entering the clean air space.

To evaluate Semiconductor Device Fabrication Modular Cleanrooms and place them in a class, the use of particles counters is employed to measure the Particles Per Cubic Metre (PPCM) of the cleanroom. Every particle counter determines the size and quantity of air particulates. ISO 1 rated cleanrooms are evaluated for the extraction of small air particulates >0.1 microns and >0.2 microns whereas an ISO 9 cleanroom, which has a similar PPCM to suburban air, will be tested for the removal of larger air contaminants >5 microns.

Containment solutions

A containment solution is suitable for you if you have a hazardous substance that needs to be removed via a filter before reaching the outside air. This can be set up in a Cleanroom that both protects products by introducing filtered air and contains hazardous materials by extracting them through a HEPA (High-Efficiency Particulate Air), ULPA (Ultra-Low Particulate Air) or carbon filter. At TCA, we can provide the solution to your containment needs preventing the exposure of hazardous chemicals to the outside atmosphere with the aim to help you become ever more compliant with your regulators.

Each containment solution we provide is unique as not two hazardous materials are the same and vary on quantities dependent on the use. This means that the level of containment can change from customer to customer. We will work with you to find the solution most practical to your use.

Airflow and Filtration

Our Cleanrooms are designed to be compliant to the specified ISO 14644-1:2015 grading. With this in mind, we take into consideration the level of air filtration required and the end function of the cleanroom. The level of air filtration required is determined by the air changes per hour (ACH), this determines how many Filter Fan Units are to be used in the cleanroom. What we also determine by the strategic positioning of the FFUs and exhausts is the flow of air around the cleanroom. This can mean the difference between a uni-directional (laminar flow) and a non-unidirectional (turbulent flow) airflow around a cleanroom, potentially leading to a contaminated product. With this in mind, we can greatly increase the number of ACH and control the air flow within the cleanroom.

Filtration of air is controlled by our ultra-quiet, high-efficiency filtration modules. These filtration modules automatically compensate for a build-up of dust and other materials that occur over time within a HEPA/ULPA filter increasing the fan speed to reach the set flow rate. This increases the life of the filter, reducing cost overtime for the end user.

Cleanrooms Customised to Your Needs

At TCA there is no such thing as a standard modular cleanroom. Each Cleanroom we design is made to fit your unique work conditions and is designed with your needs in mind. We make each modular Cleanroom to order and make you part of the design process.

With TCA you have the option of doing almost anything with a cleanroom design. This means that your Cleanroom can be many shapes and sizes fitting the most obscure of rooms and can have a range of finishes. We have yet to find a design that we could not accommodate.

Our customisable options mean that all components of the Cleanroom such as doors, windows, lighting, ceilings and filtrations can be altered to better suit your needs. You also have the option of installing furniture, air showers, pass through chambers, fire suppression, air-conditioning and much, much more. We pride ourselves in being able to meet design requests however unique in shape and size they may be.
