Silicon Ingot
Product Description
- We manufacture monocrystalline ingots, which serve as the material for silicon wafers, using a manufacturing method known as the CZ method (Czochralski method).
- It is mainly used in the etching process, which is one of the device manufacturing processes, and is an extremely important consumable material. According to the requirements of our customers, we can provide silicon ingot products of various sizes and resistivities.

Dummy Wafer
Strength
- Abundant range of products
- We have a wide variety of silicon wafers in stock
- Able to handle small lots
- We will respond to customer's requests carefully and in detail
- Short delivery time
- Thanks to our abundant stock, we are able to achieve short delivery times
- Flexible response
- We can also process from ingots for standards that cannot be covered with stock wafers
At our company, we conduct careful consultations to propose the optimal wafer that suits the customer's needs.
We will ship in formats that suit your needs, such as in a cassette case or a coin roll case. We also offer the sale of wafers that can further reduce costs, regardless of type and thickness.
Feature
Since they are often used in experiments and tests, the size and thickness vary. There may also be cases where reclaimed wafers are used.
Moreover, compared to particle-managed silicon wafer products, dummy wafers are more affordable and can accommodate small lot shipments, which are their distinctive features.
In manufacturing equipment, the first few dummy wafers are used to increase process stability, and are also used for optimizing and monitoring the manufacturing process. While dummy wafers are not suitable for device manufacturing, they are sufficiently suitable for monitoring and testing, and are often used as substitutes for new wafers.
Dummy wafers play a crucial role in all processes of wafer manufacturing, particularly in testing and adjustments.
