NanoTech 160
The NanoTech 160 is Ultratech's second-generation dual side alignment (DSA) stepper utilizing Direct Vision technology. The NanoTech 160 is specifically designed for applications where exposing both the front and backside of the wafer is necessary. Based on its patented Machine Vision System (MVS), Direct Vision incorporates an alignment system capable of aligning to targets on the back of the wafer while exposing features on the front. The NanoTech 160 offers valuable process enhancement features, including a robotic wafer handler, pre-aligner and chuck exclusively designed to handle dual side resist coated wafers with no backside contamination. The handling system is designed to support substrate thicknesses up to 1.2 mm thick and unique software and hardware features have been developed to address the requirements of extremely thick resist processes. In addition, a Windows based PC controller offers increased flexibility through a variety of alignment and focus options for improved process performance for dual side alignment applications.

Key Features and Benefits:

  • Front and backside alignment capability
  • Non-contact lithography
  • Ability to place multiple lithography layers on a single reticle
  • Pattern recognition alignment system (MVS) eliminates the need for dedicated targets
  • High wafer plane irradiance
  • Simple integration with existing processes
  • Compact system footprint
  • A proven projection lithography platform in semiconductor, thin film head and microsystems production environments


NanoTech 190
The NanoTech 190 continues the Ultratech tradition of providing superior application-specific products with low cost of ownership advantages. Building on the proven success of the Model 1700 and 1900 family, the NanoTech 190 is essential to the development of smaller dimension thin film head devices. The NanoTech 190 introduces a new theta stage design for improved accuracy and repeatability. Ultratech's patented Machine Vision System (MVS), designed especially for Femto sized rowbars, offers improved alignment capability. A Windows based PC controller offers a touch screen interface and increased flexibility in networking options. The system is available in two resolution lens options, 1.0 µm and 2.0 µm, addressing a wide range of air-bearing surfaces (ABS) design requirements.

Key Features and Benefits:

  • Custom "rowbar" application hardware and software options
  • Non-contact lithography
  • Ability to place multiple lithography layers on a single reticle
  • High wafer plane irradiance
  • Compact system footprint
  • A proven stepper platform in high volume thin film head production
