Semiconductor
The aluminum scandium sputtering target is a type of film coating material made of aluminum and scandium metal, applied in semiconductor industry.
A radio frequency (RF) filter is used for operation in mobile communication devices in the 800 to 2,500 MHz band.
SAW filters, using surface acoustic waves (SAW) that propagate across the surface of a piezoelectric substrate, are widely used as the RF filter.
More recently, commercial use of bulk acoustic waves (BAW) has progressed, and adoption of BAW is spreading in difficult bands where conventional SAW filters are not usable. In this situation, we are providing AlSc targets, with superior properties to earlier materials. AlScN alloy promises a high piezoelectric constant, some ten times higher than conventional AlN alloy.
We developed a manufacturing process to produce AlSc target with much lower oxygen - which affects piezoelectric properties - compared to existing AlSc targets.
Market Demand
On the basis of application, the SOFCs segment accounted for the maximum number of revenue shares of the global scandium metal market in 2020, and this segment is slated to continue to do so over the next 10 years. The largest market is North America, holds a share about 37%, followed by Asia Pacific and Europe, with around 36% and 26% market share respectively.
Market Supply
Hunan Oriental Scandium is one of the global main manufacturers of Scandium metal. China is the largest producer, holds a share around 58%, followed by Europe and Australia, with share 29% and 1%, separately.
