TOKYO -- Mitsui Chemicals will spend nearly 10 billion yen ($91.5 million) to ramp up Taiwanese production of a special tape used in semiconductor manufacturing as demand grows from the spread of smartphones and the Internet of Things.
Mitsui Chemicals will update its factory in the city of Kaohsiung to bring new equipment online in 2023. Annual capacity there for the tape, used on silicon wafers to protect against damage or contamination during the back-grinding process, will double to 7.6 million sq. meters.
