Silicon Ingot

Product Description

Using manufacturing method called the CZ method (Czochralski method), we manufacture single crystal ingots, which are material for silicon wafers.
This ingot is very important consumable material used primarily in etching process, which is one of device manufacturing processes.
We can provide silicon ingot products in various sizes and resistivities according to customer requirements.

Dummy Wafer

Strengths

Wide range of products
We carry wide variety of silicon wafers.
Small lots available
We can respond to customer requests with care and detail.
Short delivery times
We utilize our abundant inventory to provide products in short delivery times.
Flexible response
We can also process from ingots for standards that cannot be covered with stock wafers

We can process ingots even for specifications that are not in stock.
Through careful interviews with our customers, we propose optimal wafer that meets their needs. We can also ship in a format according to your request, such as in cassette case or coin roll case. Furthermore, we can sell wafers of any type or thickness at low cost.

Features

Because they are often used in experiments and tests, dummy wafers come in wide variety of sizes and thicknesses. In some cases, reclaimed wafers may also be used.
Compared to particle-controlled silicon wafer products, dummy wafers are cheaper and can be shipped in small lots. This is major feature of dummy wafers.
In manufacturing equipment, dummy wafers are sometimes used for first few wafers to improve process stability. It is also used to optimize and monitor manufacturing processes. Although dummy wafers are not suitable for device manufacturing, they exhibit sufficient performance for monitoring and testing purposes, and are widely used as replacement for new wafers.
Dummy wafers are indispensable and play important role in testing and adjustment in each process of wafer manufacturing.
