Amtech Systems, Inc. Announces $3 Million in New Solar Orders.

TEMPE, Ariz. -- Amtech Systems, Inc. (Nasdaq: ASYS), a global supplier of production and automation systems and related supplies for the semiconductor, silicon wafer, solar cell, and microelectromechanical system (MEMS) industries, today announced two orders totaling $3 million from the solar cell industry for Tempress(TM) brand diffusion furnace systems. The first order, accounting for $1.8 million of the total, is from a new solar customer in Asia. The second order is for an expansion project of an existing solar customer and results from a letter of intent announced at the time the earlier order was booked. Both customers are producers of photovoltaic cells.
