NY -- Standard&Poor's CreditWire 6/26/98 – Standard&Poor's today revised its outlook on Lam Research Corp. to negative from positive.

The outlook revision incorporates Lam's expectation that semiconductor capital goods sector revenues for 1998 will be 30% below 1997 levels and weak conditions will persist in 1999.
