Alpha HPA announces three deals to supply “zero-alpha radiation” materials to semiconductor sector

ASX-listed specialty chemicals company Alpha HPA says it has strengthened its position within the global semiconductor supply chain, executing three new letters of intent with unnamed global OEMs for the supply of high-purity aluminium products.

According to an update from the company on Monday, the LOIs follow “more than a year of rigorous product qualification and testing”, confirming the suitability of Alpha’s products for exacting semiconductor applications.

Alpha HPA specialises in what it says is a world-first solvent extraction purification technique (Smart SX Technology) for aluminium, producing ultra-high purity materials including aluminium oxides, hydroxides, nitrates and sulphates.

“Unlike the resources sector, each LOI in our market follows 12 to 18 months or more of intensive testing and qualification, demonstrating the reliability and performance of our materials in demanding semiconductor processes,” said Managing Director Rob Williamson. 

“This is an important technical tick for our product and a strong signal of trust and confidence from global industry leaders.” 

The three companies were not named, with “very strong NDAs” cited, and include a US OEM ] for chemical mechanical polishing (CMP) slurries, a South Korean maker of alumina fillers in advanced semiconductor packaging, and a North East Asian CMP manufacturer.

Alpha HPA added that its uptake in the sector was due to its proprietary purification delivering “zero-alpha radiation” high-purity alumina, which is “completely free from trace uranium and thorium”, and allowed for use “immediately adjacent to high-end semiconductors” as a thermal filler for heat dissipation. 

This in turn reduced cooling demand in data centres and allowed chips “to operate with higher capacity with longer life-cycles.”

Williamson added: “Even trace levels of alpha radiation create soft errors that corrupts data or logic state of the semiconductor, and we are first in the world to remove these impurities that emit alpha radiation, which end customers are strongly demanding.”

Alpha is currently in production at Stage One of its HPA First Project in Gladstone, with Stage Two – a “10-hectare, state-of-the-art facility” – currently under construction and scheduled to come online “in late 2026”.
