DESIGNED TO PRODUCE NON-CRITICAL SEMICONDUCTOR PHOTOMASKS FOR DESIGN NODES DOWN TO 130 NM, AND NON-MANHATTAN DESIGNS

The ULTRA specifically addresses the production of mature semiconductor photomasks. It is a qualified tool at a major semiconductor photomask production group. The ULTRA is used to fabricate semiconductor components for the electronics and automotive industries. These include power management, microcontrollers, LED lighting, the internet-of-things (IoT) and MEMS.

The ULTRA is an economical mask writer solution with all the features and functionality required for high throughput, precision and structure uniformity, and extremely accurate alignment. The standard configuration includes all modules (FX Fast mode, SMIF Pod, etc). The ULTRA can produce structure sizes down to 500 nm at write speeds up 580 mm² per minute, while featuring excellent critical dimension uniformity, image quality, overlay and registration. ULTRA 1 produces masks down to 180 nm nodes. ULTRA 2 will be launched in late 2021 and will target significant improvement in alignment accuracy and exposure quality – aiming at 130 nm design node. ULTRA is a compact system and fits easily into the existing mask shop infrastructure.
