ARCHIVE 2009 BREAKING TRADITIONAL BOUNDARIES - OUR INDUSTRY CHALLENGES AT TEST by Navid Shahriari Director of Sort Test Technology Development Intel Corporation S ABSTRACT uccess in the semiconductor market is never predictable but it always involves being faster, cheaper or better than your competition. This maxim holds especially true when it comes to microprocessor test. While Moore s Law has spawned a profusion of product features and functions through ever cheaper and abundant transistors, it has left test with increasing complexity and cost. Additionally, market forces necessitate ever-smaller form factors as mobile products become ubiquitous. This combination of shrinking geometry, increasing bandwidth and expanding features creates a confluence of mechanical, electrical and thermal challenges that run head-on into a severely cost constrained environment in the midst of an economic downturn. Meeting these stringent technical challenges while providing cost effective solutions, requires a collaborative response from the whole industry. Customers and suppliers alike. An outlook on the key technology drivers, leadtime, and total test costs, as well as what can be done between the suppliers and customers, to accelerate improvements beyond normal evolution, will be shared with the audience.

Risk Factors This presentation contains forward-looking statements that involve a number of risks and uncertainties. These statements do not reflect the potential impact of any mergers, acquisitions, divestitures, investments or other similar transactions that may be completed in the future. The information presented is accurate only as of today s date and will not be updated. In addition to any factors discussed in the presentation, the important factors that could cause actual results to differ materially include the following: Intel operates in intensely competitive industries that are characterized by a high percentage of costs that are fixed or difficult to reduce in the short term, significant pricing pressures, and product demand that is highly variable and difficult to forecast. Revenue and the gross margin percentage are affected by the timing of new Intel product introductions and the demand for and market acceptance of Intel's products; actions taken by Intel's competitors, including product offerings, marketing programs and pricing pressures and Intel s response to such actions; Intel s ability to respond quickly to technological developments and to incorporate new features into its products; and the availability of sufficient components from suppliers to meet demand. Factors that could cause demand to be different from Intel's expectations include customer acceptance of Intel and competitors products; changes in customer order patterns, including order cancellations; changes in the level of inventory at customers; and changes in business and economic conditions. The gross margin percentage could vary significantly from expectations based on changes in revenue levels; product mix and pricing; capacity utilization; variations in inventory valuation; excess or obsolete inventory; manufacturing yields; changes in unit costs; impairments of long-lived assets, including manufacturing, assembly/test and intangible assets; and the timing and execution of the manufacturing ramp and associated costs, including start-up costs. Expenses, particularly certain marketing and compensation expenses, vary depending on the level of demand for Intel's products, the level of revenue and profits and impairments of long-lived assets. Intel is in the midst of a structure and efficiency program which is resulting in several actions that could have an impact on expected expense levels and gross margin. The tax rate expectation is based on current tax law and current expected income. The tax rate may be affected by the closing of acquisitions or divestitures; the jurisdictions in which profits are determined to be earned and taxed; changes in the estimates of credits, benefits and deductions; the resolution of issues arising from tax audits with various tax authorities, including payment of interest and penalties; and the ability to realize deferred tax assets. Gains or losses from equity securities and interest and other could vary from expectations depending on equity market levels and volatility; gains or losses realized on the sale or exchange of securities; gains or losses from equity method investments; impairment charges related to marketable, non-marketable and other investments; interest rates; cash balances; and changes in fair value of derivative instruments. Intel s results could be affected by the amount, type, and valuation of share-based awards granted as well as the amount of awards cancelled due to employee turnover and the timing of award exercises by employees. Intel's results could be impacted by unexpected economic, social, political and physical/infrastructure conditions in the countries in which Intel, its customers or its suppliers operate, including military conflict and other security risks, natural disasters, infrastructure disruptions, health concerns and fluctuations in currency exchange rates. Intel's results could be affected by adverse effects associated with product defects and errata (deviations from published specifications), and by litigation or regulatory matters involving intellectual property, stockholder, consumer, antitrust and other issues, such as the litigation and regulatory matters described in Intel's SEC reports. Please refer to Intel s most recent Earnings Release and most recent Form 10-K or 10-Q filing for more information on the risk factors that could cause actual results to differ materially. 3/2009 Breaking Traditional Boundaries OUR Industry Challenges at Test 33 March 8-11, 2009 17
