(Reuters) - The U.S. government has been slow to approve licenses for American companies like Lam Research and Applied Materials to sell chipmaking equipment to China semiconductor giant SMIC, several sources said, as the impact from global shortage spreads.
Licenses for U.S. suppliers to ship much of an estimated $5 billion dollars' worth of parts and components still have not come through, industry sources said, though many companies sought them soon after the company was blacklisted in December. Certain licenses have been granted, including for small numbers of expensive equipment in recent days.
