TAIPEI -- At least five suppliers to Taiwan Semiconductor Manufacturing Co. and Intel have delayed construction of facilities in Arizona, a sign that rebuilding America's chip supply chain is a bigger challenge than expected.
Chemical and material makers LCY Chemical, Solvay, Chang Chun Group, KPPC Advanced Chemicals (Kanto-PPC) and Topco Scientific all announced plans and bought land to build facilities in Arizona after the world's two top chipmakers, TSMC and Intel, rolled out their own multi-billion-dollar investments in the state.
