Item 7.01.   Regulation FD Disclosure
On July 29, 2008, Lam Research Corporation (the “Company”) issued a press release and held a conference call announcing its earnings for the fiscal quarter ended June 29, 2008. Following the conference call, investors expressed interest in the Company’s backlog. The Company had planned to disclose backlog in its Annual Report on Form 10-K for the fiscal year ended June 29, 2008 to be filed this quarter.
The Company’s unshipped orders backlog includes orders for systems, spares, and services where written customer requests have been accepted and the delivery of products or provision of services is anticipated within the next 12 months. The Company’s policy is to revise its backlog for order cancellations and to make adjustments to reflect, among other things, spares volume estimates and customer delivery date changes. In general, the Company schedules production of its systems based upon purchase orders in backlog and its customers’ delivery requirements. Included in the Company’s systems backlog are orders for which written requests have been accepted, prices and product specifications have been agreed upon, and shipment of systems is expected within one year. The spares and services backlog includes customer orders for products that have not yet shipped and for services that have not yet been provided. Where specific spare parts and customer service purchase contracts do not contain discrete delivery dates, the Company uses volume estimates at the contract price and over the contract period, not exceeding 12 months, in calculating backlog amounts. Generally, orders for the Company’s products and services are subject to cancellation by its customers with limited penalties. Because some orders are received for shipments in the same quarter and due to possible customer changes in delivery dates and cancellations of orders, the Company’s backlog at any particular date is not necessarily indicative of business volumes nor actual revenue levels for succeeding periods. The Company’s backlog as of June 29, 2008 approximated $400 million.
The information in this Current Report on Form 8-K is furnished pursuant to Item 7.01 and shall not be deemed “filed” for the purposes of Section 18 of the Securities Exchange Act of 1934, as amended, or otherwise subject to the liabilities under that Section. Furthermore, the information in the Current Report on Form 8-K shall not be deemed to be incorporated by reference into the filings of the Company under the Securities Act of 1933, as amended.



Pursuant to the requirements of the Securities Exchange Act of 1934, the Registrant has duly caused this report to be signed on its behalf by the undersigned hereunto duly authorized.
