TSMC (TSM) is pouring $1.4B into ASML, shortly after Intel made a $4.1B investment in the leading chip equipment maker. Like Intel, TSMC is providing both equity (€838M for a 5% stake) and an R&D commitment (€276M). The goal is to keep Moore's Law going by commercializing EUV lithography, and lower chip costs by speeding up the arrival of 450mm wafers. And perhaps extend TSMC and Intel's technology leads over smaller rivals (I, II). ASML has also asked Samsung to invest.
