April 15 (Reuters) - Applied Materials AMAT.O has bought a 9% stake in BE Semiconductor industries (BESI) BESI.AS, the U.S.-based computer chip equipment supplier said on Monday.

The Dutch semiconductor advanced packaging firm produces the world's most accurate hybrid bonding tool, a critical chip technology allowing two chips to be bonded directly on top of each other.

Applied Materials said it did not intend to seek board representation at BESI.
