Product Applications:

Lanthanum metal targets possess excellent dielectric constants, making them ideal high-K gate dielectric materials. These targets are used to increase the gate dielectric constant of transistors in processes below 5nm and reduce gate leakage current.

 

Technical Advantages:

1. Using high-purity lanthanum metal as the raw material, the absolute purity of the product can reach up to 4N. The control of key impurities is strict, with O ≤ 2000 ppm and C ≤ 100 ppm.

2. The average grain size is less than 100 μm.

3. Customized production of non-standard sizes is supported.
