ITEM 5.   OTHER EVENTS


        (a)     On August 18, 1997, Lam Research Corporation (the "Company")
announced that, subject to market and other conditions, it intended to raise
$300 million (excluding any proceeds of the over-allotment option) through a
private placement of convertible subordinated notes within the United States to
qualified institutional investors and outside the United States to non-U.S.
investors. The Company contemplated that the notes would have a term of five
years and be convertible into the common stock of the Company. The Company
stated that it intended to use the net proceeds of the offering for general
corporate purposes, including working capital.


        (b)     On August 19, 1997, the Company announced that it had sold $310
million of 5% convertible subordinated notes due 2002 in an offering within the
U.S. to qualified institutional buyers in accordance with Rule 144A and outside
the U.S. to non-U.S. persons. The notes are convertible into the common stock of
the Company. The offering closed on August 26, 1997. The Company has granted the
initial purchasers a 30-day option to purchase an additional $45 million of
notes to cover over-allotments, if any. No other terms were disclosed.


        This announcement is neither an offer to sell nor a solicitation to buy
any of these securities.

        The securities will not be registered under the Securities Act of 1933,
as amended (the "Securities Act"), or any state securities laws, and unless so
registered, may not be offered or sold in the United States except pursuant to
an exemption from, or in a transaction not subject to, the registration
requirements of the Securities Act and applicable state securities laws.


        Copies of the press releases with respect to the private placement of
the convertible subordinated notes are attached as exhibits to this report.
