[Wolfa New Products] 23 New Semiconductor Precursors And High-End Pharmaceutical Intermediates Added (December 2025)

As semiconductor process nodes evolve towards 3nm and more precise processes, and as new drug development demands increasingly precise synthetic techniques, the scientific research and industrial sectors are facing unprecedented challenges to the purity and consistency of upstream chemical materials.

In response to this demand, Wolfa officially announced this month the expansion of our high-purity chemicals portfolio. This update highlights the following key chemicals, covering ALD/CVD precursors for logic and memory chip manufacturing, as well as highly reactive metal reagents for complex organic synthesis.

The following is a list of new products and their application categories.

High-k Material: Hf and Zr Precursor

We now offer high-purity hafnium-based precursors suitable for depositing high-quality HfO2 thin films. We have also launched two zirconium-based precursors that exhibit excellent step coverage. 

For the ALD process, we rigorously separated the Zr/Hf intercompany impurities in the aforementioned precursors to ensure electronic-grade purity. The following is a detailed product list.

Silicon Sources for Thin Film Deposition: Chlorosilanes & Aminosilanes

For the deposition of insulating and barrier layers such as SiO2, SiN, and SiOC, we have expanded the selection of silicon precursors to meet the process requirements of different temperature windows. 

We added a classic silicon source adapted to high-temperature CVD processes:

And highly reactive aminosilanes can achieve low-temperature deposition and avoid chlorine contamination. 

Metal Gate and Interconnect Materials

To address the resistance issue in nanoscale interconnects, we have introduced a variety of refractory metal precursors, which are widely used in the fabrication of diffusion barrier layers and contact electrodes. 

Titanium

Tungsten

Molybdenum

Organic Synthesis and Medicine

Wolfa's highly active reagents are suitable for use in pharmaceuticals and fine organic synthesis. They are all packaged in anhydrous and oxygen-free environments to ensure immediate use upon opening. 

Specialty Intermediates and Basic Solvents

To improve our supply chain, we have also added the following products.
