Photomasks are the master plates for semiconductor chip manufacture. They are produced by forming fine circuit patterns on high-purity glass substrates. Toppan has manufactured photomasks since the 1960s and is an industry leader in technology and supply volume.
LSI Design / LSI Turnkey Services
Toppan has been providing semiconductor integrated circuit design services for 50 years. Today we provide turnkey services that go beyond simple circuit design to coordinate every process from semiconductor device prototyping to mass production.
Nanoimprint is a transfer technology for manufacturing minute structures. On account of its low cost in comparison with semiconductor photolithography, it is expected to be used for lens arrays, optical devices and displays, medical applications, and a wide range of other purposes. Toppan applies microfabrication technology honed in the production of semiconductor photomasks to develop an array of molds.
Color Filter Arrays & Micro-Lens Arrays (On-chip Color Filters)
Image sensors are semiconductor devices that convert light entring a lens into an electrical signal. Color filter arrays consist of filters formed on each photodiode on a sliconwafer. Micro-lenses are formed on the color filter to enhance light covergence and sensitivity.
Semiconductor Packaging Materials
Semiconductor packaging materials support and fix IC chips. They also function as connection pins when chips are mounted onto printed wiring boards. Development and manufacturing at Toppan are underpinned by advanced photolithography and etching technologies honedover many years.
Photo Etched Parts
Photo etching is a processing technique that makes advanced microfabrication possible. It involves chemical corrosion of a metal surface followed by selective removal of parts of the material.
