Factors Affecting the Cost of Semiconductor Cleanrooms and Cost Estimation

In the semiconductor industry, the cleanliness of the production environment plays a decisive role in product quality. The construction of semiconductor cleanrooms is the key to ensuring the smooth progress of semiconductor production. As Guangzhou Cleanroom Construction Co., Ltd., a manufacturer specializing in the production of purification equipment, today we will have a detailed discussion with you about the factors affecting the cost of semiconductor cleanrooms and the methods of cost estimation.

I. Key Factors Affecting the Cost

1. Purification Level：Semiconductor production has extremely high requirements for cleanliness. Common purification levels include Class 100, Class 10, or even higher levels. The higher the purification level, the stricter the control of pollutants such as dust particles and microorganisms in the air. More advanced purification equipment and technologies are required, and the cost will naturally increase significantly. For example, compared with a Class 100 cleanroom, a Class 10 cleanroom has higher requirements in terms of filter accuracy and air flow organization, and the cost may be several times higher.

2. Workshop Area：The size of the workshop area directly affects the consumption of materials and equipment. When constructing a large - area workshop, although there may be a certain reduction in unit cost due to economies of scale, the overall material and equipment procurement costs as well as labor costs will still increase significantly with the increase in area. In addition, the layout and air flow organization design of a larger - area workshop are more complex, which also adds to the cost.

3. Purification Equipment：Purification equipment is the core investment part of a semiconductor cleanroom. High - efficiency air filters, advanced air - conditioning systems, ultra - pure water preparation equipment, etc., are all crucial to ensuring that the workshop environment meets production requirements. The prices of equipment with different brands and performances vary greatly. For example, the price of high - end imported air filters may be several times that of ordinary domestic filters, and the price of high - precision ultra - pure water preparation equipment is even more expensive.

4. Decoration Materials：The decoration materials used for walls, floors, and ceilings need to have characteristics such as anti - static, corrosion - resistance, and easy - cleaning. Special materials such as anti - static epoxy self - leveling floor materials and dust - resistant color - coated steel plate walls are more expensive than ordinary decoration materials. Moreover, in order to meet the strict environmental requirements of semiconductor production, the quality standards of materials are higher, which further drives up the cost.

II. Examples of Cost Estimation Methods

1. Simple Estimation：For a preliminary cost estimate, it can be roughly calculated first according to the purification level and area. Suppose a semiconductor cleanroom with a Class 100 purification level, the cost per square meter is approximately 3,000 - 5,000 yuan. If the workshop area is 1,000 square meters, the preliminary estimated cost is between 3 million and 5 million yuan. However, this is only a very rough estimate, and the actual cost will be affected by many factors.

2. Detailed Estimation：A detailed cost estimate needs to consider every specific item. First, list all the equipment lists, including air purification equipment, ultra - pure water equipment, waste gas treatment equipment, etc., and calculate the equipment procurement cost according to the brand, model, and quantity of the equipment. Then, calculate the decoration material cost according to the area of the walls, floors, and ceilings and the types and specifications of the selected materials. Add the labor cost, which can be estimated according to the local labor market price and the construction difficulty. Finally, some unforeseen costs, such as design changes and unexpected situations during construction, also need to be considered. Generally, 5% - 10% of the total cost can be reserved.

The cost of a semiconductor cleanroom is comprehensively affected by various factors. When making a cost estimate, it is necessary to consider various factors comprehensively and carefully.
