Although it created a division to manufacture photoresists, IBM ’ s own IC factories didn ’ t dare use them. Even the chemicals giant BASF failed in its attempt to enter the photoresist field. These examples demonstrate the difficulty involved in entering the photoresist market.
以 IBM 為例，後來也自行成立化學部門生產光阻劑，產品出爐後自家集團內的 IC 廠卻不敢使用；甚至連化學巨人巴斯夫投入光阻劑，最後都功敗垂成，其難度可見一斑。
