GaAs device growth rates will result in further declines in the total available market (TAM) for GaAs bulk substrates.
It concludes that demand for semi-insulating GaAs bulk substrates declined by nearly 2 percent in 2013. The volume decline and increasing price erosion caused revenues to decline by 8 percent. As a result, bulk substrate demand will grow with a CAAGR of less than 1 percent through 2018. With price erosion returning to historical levels, the slow growth of substrate production will drop revenues to $160 million in 2018.
Eric Higham, Strategy Analytics’ service director for advanced semiconductor applications commented: «There will be challenging times ahead for GaAs substrate manufacturers. «The emergence of CMOS PAs and multi-mode, multi-band GaAs PAs will both act to slow growth and reduce revenue.»
Asif Anwar, director in the firm’s strategic technologies practice added: «The good news is that prior disruptions in the GaAs bulk substrate supply chain appear to have been addressed, but this means a return to historical price erosion rates that will pull revenues down.»
± 1.2µm thickness and parallelism to 10 arc-sec, depending upon size. Second only to diamond in terms of hardness, they are chip-, chemical-, and scratch-resistant and can be supplied with reference flats and laser markings.
Meller Sapphire Wafer Carriers are priced according to size, configuration, and quantity; with four to six weeks typical delivery.
Leading European lab orders Riber MBE system
Third sale of new compound semiconductor research system
Riber is announcing a third order for its Compact 21 DZ molecular beam epitaxy (MBE) system, which is designed for fundamental research on compound semiconductors. The machine will enable a leading European laboratory to increase its development capabilities for designing III-V semiconductor devices.
Meller Optics introduces custom Sapphire wafer Carriers
Carriers more durable than quartz and impervious to polishing abrasives and solvents
Meller Optics, of Rhode Island, USA, has introduced custom fabricated sapphire wafer carriers for thinning semiconductors. The carriers are more durable than quartz and are impervious to polishing abrasives and solvents, says the company.
Meller sapphire wafer carriers feature Moh 9 hardness and superior strength due to off-axis crystal growth; permitting their custom fabrication as thin as 0.018in in 2 to 6in diameter sizes. Suited for the uniform thinning of semiconductor materials such as GaAs, they can be custom perforated for vacuum hold-down or de-lamination and can withstand repeated use.
The carriers provide part-to-part uniformity with 134

After two machines sold during the first half of 2014, this new purchase order confirms the commercial success of the new Compact 21 DZ system since its launch onto the market at the end of 2013, says Riber.
The Compact 21 DZ system is aimed at compound semiconductor research particularly structures based on III-V, II-VI, GaN materials, graphene, and oxides. It is well suited for the development of emerging technologies, such as UV LEDs or high- performance solar cells. Compact and flexible, it is designed to meet the needs of users looking to minimise their fixed costs, according to the company.
