Heidelberg Instruments receives order for a semiconductor laser mask writer

ULTRA – a laser mask writer for semiconductor photomasks, which are the basis for electronic devices such as microcontrollers

Heidelberg, Germany, 26 August 2021: Heidelberg Instruments announced order for an ULTRA Semiconductor Laser Mask Writer from a large photomask production group in China.

ULTRA Semiconductor Laser Mask Writer is the industry’s most economical solution for the production of photomasks with a 180 nm design node.  With its high throughput, small minimum feature size, excellent overlay, 2nd layer alignment, and CD uniformity, ULTRA is an ideal tool to address diverse applications in the semiconductor industry.

ULTRA features multiple high-speed Spatial Light Modulators (SLM) to achieve a finer address grid and higher throughput.  Its high-speed data path is designed to handle the most complex geometries and dense patterns while maintaining high exposure speed.  In addition, a custom-designed objective lens with NA of 0.9 and an address grid of 5nm, along with excellent focus control, contribute to outstanding CD Uniformity.
