Taiwan Build-up Film(TBF) is mainly used in ABF substrate, which can replace Ajinomoto build-up Film.

More than 90% of the key materials of ABF substrate - build-up Film depends on imports. As the output value of ABF substrate, Taiwan accounts for 31% of the world and the output is the world NO.1. The risk of key materials being monopolized by large foreign manufacturers is high, it is easy to cause supply chain interruption such as trade policies, natural disasters and geopolitics.

In order to overcome the difficulty that ABF materials are monopolized by Japanese manufacturers and lack of production capacity. WaferChem has devoted all its efforts to R&D advanced  semiconductor materials. It is also the only one who has invested in the build-up film materials for ABF substrate in Taiwan, we hope to promote the localization of Taiwan semiconductor material supply chain.
