10. How is an Air Shower Important for your Clean Room Semiconductor?

An air shower is responsible for the removal of contaminant particles dislodged on the clothing surface of the person entering the cleanroom.

It bombards streams of high-velocity air which knock off the particles from the surface thus cleaning it.  This ensures that any person going inside the clean room has particulate-free clothes, skin, and body.

The purpose of an air shower is to reduce the entry of contaminants in the Clean Room Semiconductor. It is located at the entrance and the person has to complete one cycle before engaging in the semiconductor manufacturing process.

The contaminants include skin flakes, hair, and dirt, etc. The person enters from one side and the door gets locked automatically. One cycle completes in 20 seconds and the other door opens automatically.

However, the proper protocol to enter the air shower must be followed so that there is no chance of contamination in the semiconductor manufacturing process.

Other important components of the air shower room are the HEPA filter, recirculation system, an interlocking mechanism. The interlocking system is to prevent cross-contamination.

11. Why Pass-Through Windows are Necessary for your Clean Room Semiconductor?

A pass-through window is beneficial in Clean Room Semiconductor because it aids in the transfer of materials from one place to another.

Also, it is done without exposing the material to the outside environment. It is a cavity in the walls of the clean room that has two open ends.

The object is placed from one side and the door gets locked automatically. It remains in the cavity for some time until complete decontamination occurs.

Red light indicates that the pass-through clean room window is being used at the moment. Once the decontamination process is complete, the door opens automatically and the object can be received from the other end.

Now the green light is turned on which indicates that it is ready to be used for the next cycle.

16. How to Classify Contamination Sources in your Clean Room Semiconductor?

The contamination sources in your Clean Room Semiconductor can be classified into the following categories:

Biological

Various kinds of bacteria, spores, and viruses are included in the biological sources of contamination in the case of a semiconductor cleanroom.

Humans

Saliva and water droplets that may be produced due to coughing, sneezing, or normal talking can prove to be a major source of contaminating your product.

Chemicals

Sodium content released from your hands is a big contaminant source. Also, iron getting off from rusty surfaces can compromise cleanliness.

Harmful gases produced from various machines can contaminate this controlled area.

Particles

Skin flakes, dandruff particles, dust, or dirt particles from your shoes, clothes, and your bodies can be dangerous for the cleanliness level which needs to be maintained over a narrow range.

Dirt, skin, or dandruff shedding from the human body contributes a major portion of contamination-producing sources.

17. What is Humidity Control in a Clean Room Semiconductor?

Controlling the relative and absolute humidity in a Clean Room Semiconductor is essential for the users as well as for the normal functioning of your cleanroom.

This is important because various steps of semiconductor manufacturing processes being carried out require a specific humidity level. Also, it is crucial for the quality of the product and beneficial to control the electrostatic discharge.

The best way to control humidity is to control the makeup moisture inside the space. Also, the recirculation of air is strictly monitored.

The main reason for the development of humidity excursions is the typical wet processes. Other reasons include the transfer of moisture content among different parts of your cleanroom.

So, an excellent make-up control can surely provide you with the controlled operation of your Clean Room Semiconductor. This is also helpful in reducing energy consumption.

If you want to control the humidity using any dehumidification treatment of the recirculation air, the costs will be much higher.

18. Why is Pressure Control Important in your Clean Room Semiconductor?

Several important reasons are present for controlling the pressure inside your Clean Room Semiconductor.

Controlling the pressure has a big effect on different atmospheric processes such as the deposition of the film. It also serves as a barrier to the development of contamination problems.

The main purpose of introducing positive pressurization is to protect the Clean Room Semiconductor from external contamination sources such as moisture and particles.

The main purpose of negative pressurization is to stop the exiting of hazardous materials such as gold or potassium.

This process also affects the quantity and quality of the makeup air, which can resultantly control the amount of energy consumed.

19. What are the Typical Measures to Control Contamination in your Clean Room Semiconductor?

Contamination control and prevention need proper planning and execution of these plans.

Designing

A Clean Room Semiconductor is specially designed using special principles and technologies, to allow good airflow and reduce the chances of contamination in it.

Cleaning and Maintenance

Cleaning and maintenance are two essential things that can decrease the chances of contamination.

If you follow the suggested procedures using suitable products for both jobs, you can increase the life of your Clean Room Semiconductor.

HEPA

The High-Efficiency Particulate Air Filter which acts as a primary filter is very useful for controlling contamination. Even if tiny particles of 0.3-micron size are present, these filters will efficiently filter them within minimum time.

Human Behavior

It is strictly prohibited to run or move fast when working inside a controlled space. Human activities can have a large effect on the contamination level inside the cleanroom.

Electrostatic Discharge

Electrostatic charges are produced as a result of the transfer of electrons between two locations.

This is damaging for your clean room but the simplest way is to use ESD protective materials to stay protected from its harmful effects.

So, using a special wrist strap, and ESD-protected footwear or clothes can surely decrease the contamination.

20. Why Gowning is Essential While Dealing With your Clean Room Semiconductor?

The main purpose of gowning for the Clean Room Semiconductor is the maintenance of the cleanliness level in it. A major portion of the dust and other contaminants comes from human beings.

Therefore, it is important to reduce the contamination that can occur due to human hair, clothes or skin, so that a clean environment can be formed.

Humans drop chemicals as well as particle contaminants, which can be harmful and disturbing for the normal environment of the cleanroom.

Passing from an air shower room along with proper gowning will be more helpful in minimizing the particles before entering your Clean Room Semiconductor.

Essentially Required Attire List

Here is a list of some essential products that are included in the gowning procedure:

• The shoe covers are important as they will reduce the high dirt content that may come from your feet or shoes.

• A hood is important to entirely cover your body from the head to the neck.

• A bouffant will aid in reducing the dropping off of particles in the area.

• To cover your body from your neck to the ankles, a coverall will be helpful.

• Special eyewear can be used to achieve protection for your eyes from unnecessary particles entering them.

• To protect your hands, and the controlled space from particulates being released from your hand, you must wear gloves. It will also help you to avoid contamination of the workbenches.

• To keep the Clean Room Semiconductor safe from droplets or particles that can come from your breath, wearing a face mask is the best solution.
