Product Description

In the advanced manufacturing fields like semiconductor integrated circuits, any minor contaminants including particle matter, metallic impurities and organic residues, will degrade device performance or even cause device failure. Wet cleaning is thus an essential process in production to ensure the cleanliness of the device. Quartz wafer cleaning tanks, the indispensable containers in this process, providing a suitable reaction environment for oxide layer stripping, organic contaminant decomposition and metallic ion extraction of wafers.

Advantages of Semicorex quartz wafer cleaning tanks

1. Low impurity release

The quartz materials used for Semicorex quartz wafer cleaning tanks have ultra-high purity, and their key metallic impurities including Na, K, Fe and Cu, are controlled below ppb levels. This remarkable property can minimize the risk of metallic contamination originating from quartz wafer cleaning tanks during wafer cleaning processes, thus ensuring the wafer cleanliness and production yield.

2. Reliable chemical stability

Wet cleaning processes need to use corrosive solutions such as H₂SO₄, HNO₃, and aqua regia. These solutions exhibit strong corrosiveness toward most materials, especially under high-temperature operating conditions. Semicorex quartz wafer cleaning tanks boast reliable anti-corrosion performance, can consistently contain these corrosive solutions while maintaining stable structural integrity.

3. Excellent thermal performance

In order to speed up chemical reactions and enhance the cleaning effect, many wet cleaning procedures, such as RCA standard cleaning, require high temperatures. Semicorex quartz wafer cleaning tanks can effectively provide a constant thermal condition for temperature-dependent chemical reactions because of their stable thermal stability, which allows them to be free from creaking caused by sudden temperature changes.
