Electronic-grade thiourea, a key component of electronic chemicals, is defined as a key chemical used in the electronics industry during the semiconductor device manufacturing process. Its high purity, low moisture content, and low impurity content make it an indispensable chemical raw material for electronic devices. Electronic-grade thiourea is primarily used in cleaning, etching, and chemical vapor deposition (CVD) processes in semiconductor manufacturing, playing a crucial role in ensuring the reliability and performance of electronic devices.
From a classification perspective, electronic-grade thiourea is primarily divided into two categories: standard electronic-grade and ultra-high-purity electronic-grade. Standard electronic-grade thiourea generally has a purity of over 99.5%, while ultra-high-purity electronic-grade thiourea can reach 99.999% or even higher. With the continuous advancement of semiconductor technology, the purity requirements for electronic-grade thiourea are also increasing. Globally, electronic-grade thiourea production is primarily concentrated in Asia, Europe, and the United States.
