In the booming semiconductor industry, high-purity metal materials play a vital role. With the continuous progress of semiconductor technology and the increasingly sophisticated chip manufacturing process, the demand for high-purity metal materials is increasing day by day, and its application scope and importance are also becoming prominent.
High-purity metal materials refer to metals with high purity and impurities often calculated in parts per million or even lower. Due to their extremely high purity, their properties are significantly different from those of general industrial pure metals, and thus they have acquired special uses. In the field of semiconductors, the purity of metal materials has a critical impact on the performance, stability and reliability of chips. When the purity of the metal does not reach a certain standard, the presence of impurities will mask the intrinsic properties of the metal and affect the electrical, optical and thermal properties of semiconductor devices. For example, in the chip manufacturing process, the conductivity of metal wires can be reduced due to the presence of impurities, resulting in increased delay and loss of signal transmission; Impurities may also cause problems such as leakage and short circuits in semiconductor devices, which seriously affect the quality and service life of chips. Therefore, high-purity metal materials are the foundation and key to semiconductor chip manufacturing.
