Canon Launches FPA-3030i5a Semiconductor Lithography System Supporting Reduced Cost of Ownership Manufacturing for Small Substrates
SINGAPORE, 27 October 2020 — Canon announced today the launch in Japan of the FPA-3030i5a, the newest entry in the company’s lineup of i-line1 stepper semiconductor lithography systems that support the manufacture of such devices as compound semiconductors and reduce cost of ownership (CoO), an indicator of the total cost required for semiconductor manufacturing.
The FPA-3030i5a semiconductor lithography system is designed to process small substrates of 8 inches or less, and supports not only silicon wafers, but also compound semiconductor materials such as SiC (silicon carbide) and GaN (gallium nitride). This helps make possible the manufacture of various semiconductor devices that are expected to see increased demand in the future, including high-power devices for automobile electrification and high-bandwidth devices for 5G communication. In addition, the hardware and software have been upgraded from those of the system’s predecessor model, the FPA-3030i5+ stepper (released in June 2012), helping to reduce CoO.
The FPA-3030i5a employs a feeder system capable of handling a variety of wafer materials and sizes, including compound semiconductors with a diameter from 2 inches (50 mm) to 8 inches (200 mm). In addition, thanks to a new off-axis alignment scope to illuminate and measure wafer alignment marks without passing through a projection lens, the system makes possible alignment measurement at a wide range of illumination wavelengths.
Backside alignment, or Through Silicon Alignment (TSA) is also available as an option to adapt a variety of customer manufacturing processes. The FPA-3030i5a also inherits the imaging performance of its predecessor model, achieving exposure resolution of 0.35 micrometer2 line width patterns. Through the implementation of these functions, system owners are able to manufacture specialty power and communication devices using a wide range of wafer materials including compound semiconductors such as SiC.
By adopting such hardware as a new alignment scope that shortens the measurement time of alignment marks and a high-speed feeder system, as well as upgraded software, the FPA-3030i5a achieves 123 wafers per hour (wph), an approximately 17% improvement in productivity compared with its predecessor model. In addition, by changing the chamber temperature control system, which maintains the lithography system in a clean environment and constant temperature, reducing power consumption by approximately 20% compared to the FPA-3030i5a’s predecessor model. Through such improvements, the system helps meet the needs of users seeking reduced CoO.
CoO (Cost of Ownership)
The total cost required for capital investment and operation of a semiconductor manufacturing system. This is one of the indicators of the productivity of the manufacturing system and its processes on the mass production and is taken into consideration by manufacturers when selecting equipment.
Lineup of Semiconductor Lithography Systems for Small Substrates
Canon's lithography systems for small substrates support not only silicon wafers, but also compound semiconductor wafers, which comprise a variety of small wafers. The company’s current lineup consists of three products: the KrF excimer laser stepper3 FPA-3030EX6 (released in July 2016) serves users who require high resolution; the i-line stepper FPA-3030iWa (released in February 2020) supports a wide exposure range and uses a projection lens with a variable NA (numerical aperture) from 0.16 to 0.24, which ensuring high DOF (depth of focus) to make possible exposure with high accuracy and uniformity.
