HPA use in Semi-Conductor Applications

Perth, Nov 26, 2019 AEST (ABN Newswire) - Altech Chemicals Limited (googlechartASX:ATC) (googlechartA3Y:FRA) is pleased to provide information regarding the use of high purity alumina (HPA) in the manufacture of epoxy moulding compounds (EMC's) that are used in the semi-conductor industry to improve heat dissipation. Altech recently commenced an investigation of the EMC for semi-conductor market for the purpose of targeting some of its future HPA product into this market segment.

Introduction of alumina into EMC's used in semi-conductors Typically industrial-strength epoxy compounds are used for the package assembly of semi-conductors, as the epoxy compounds provide the required physical protection, mechanical strength, as well as a number of desired performance properties - primarily in relation to heat and moisture, both of which can destroy a semi-conductor, warp an electronic device (that the semi-conductor is used in), or even cause a device to catch fire.

Electronic devices continue to become more compact - Moore's Law - the exponential growth in the number of transistors that can be packed into a single semi-conductor. However, thermal or heat dissipation is a real problem as semi-conductors continue to reduce in size and contain more transistors. It is suggested that heat could represent the ultimate barrier to the ever smaller and more powerful semi-conductors that end-users have become accustomed to.

The epoxy resins that have traditionally been used for semi-conductor package assembly are reaching their limits in terms of effective heat dissipation. However, adding thermally conductive materials into the resins has been demonstrated to improve heat dissipation and thereby improve the protection of semi-conductors against heat related failure. The thermally conductive fillers that are being used include HPA, crystalline silica, and magnesium oxide. HPA however is a preferred filer, due to its heat conductivity (7 times higher than silica) and a much lower thermal expansion coefficient (50% lower).

Altech's preliminary investigation into the demand for high quality HPA from the EMC semi-conductor market indicates a global market size in the range of 700 - 900tpa, with a price of US$100/kg being commanded by product that meets required specifications. Year-on-year growth in the market is typically in line with growth experienced in the semi-conductor business. Altech believes that its low sodium HPA, and the morphology of its HPA, may be ideal for the EMC semi-conductor application, and the Company intends to commence the development of a product specification that may suit this market sector's requirements.

About Altech Batteries Ltd

Altech Chemical Ltd ASX:ATCAltech Batteries Limited (ASX:ATC) (FRA:A3Y) is a specialty battery technology company that has a joint venture agreement with world leading German battery institute Fraunhofer IKTS ("Fraunhofer") to commercialise the revolutionary CERENERGY(R) Sodium Alumina Solid State (SAS) Battery. CERENERGY(R) batteries are the game-changing alternative to lithium-ion batteries. CERENERGY(R) batteries are fire and explosion-proof; have a life span of more than 15 years and operate in extreme cold and desert climates. The battery technology uses table salt and is lithium-free; cobalt-free; graphite-free; and copper-free, eliminating exposure to critical metal price rises and supply chain concerns. 

The joint venture is commercialising its CERENERGY(R) battery, with plans to construct a 100MWh production facility on Altech's land in Saxony, Germany. The facility intends to produce CERENERGY(R) battery modules to provide grid storage solutions to the market.
