        Making and selling semiconductors means
        a large investment. There are two ways to
        do it:  Develop your own chip-making fac-
        tories or buy someone else’s.   Typically,
        neither way is cheap nor easy.

        The Chinese would love to buy advanced                  Much advanced semiconductor manufacturing equipment
        front-end semiconductor manufacturing                   used at the front-end, such as this Applied Materials Cen-
        equipment from leading U.S. makers such                 tris etching system, is considered highly sesitive and may
        as Advanced Materials, Lam Research and                 not be sold to China or many other countries.
