Besides spending to address manufacturing constraints

Qualcomm Inc. QCOM -0.36% provided more evidence louis vuitton sunglasses of strong demand for its smartphone chips, but said filling customer orders is presenting a new challenge.

The San Diego-based company, while reporting record financial results for its fiscal second quarter, said Wednesday that growth in the current quarter could be limited by a shortfall in gucci sunglasses supplies of chips based on a new manufacturing process.

"Chasing supply is our biggest issue," said Paul Jacobs, Qualcomm's chief executive, in an interview. "Customers don't like not getting what they asked for, that's for sure."

Qualcomm, like many other burberry handbags companies that design chips for cellphones, relies heavily on the manufacturing services of Taiwan Semiconductor Manufacturing Co. TSM +0.46% That company has started making chips using a production recipe that creates chips measured at 28 nanometers. A nanometer is a billionth of a meter.

Mr. Jacobs said "there are just not enough machines" in TSMC's factories to build chips Qualcomm has designed for the 28-nanometer production process. As a result, Qualcomm will burberry ties boost its spending to help other manufacturing companies begin to help meet its needs for the new chips, he said.

The issue didn't pose any problems in the second quarter ended March 25. Qualcomm's net income for the quarter more than doubled to $2.23 billion, or $1.28 a share, from $999 million, or 59 cents, a year earlier.

Qualcomm's results for the latest period include louis vuitton handbags a $1.9 billion gain on the sale of wireless spectrum to AT&T Inc. T -0.45% Excluding the gain and other results of its investment initiatives, Qualcomm said its earnings per share rose 17% to $1.01. Revenues swelled 28% to $4.94 billion from $3.87 billion, while unit chip sales rose 29% to 152 million.

For the current quarter, Qualcomm projected revenue of $4.45 billion to $4.85 billion, and earnings per share excluding investment gains or losses of 83 cents to 89 cents. Analysts on average had been expecting revenue of $4.8 billion and earnings of 90 cents a share on that basis, according to Thomson Reuters.

The company's third-quarter forecast for shipments of 144 million to 152 million chips, which Mr. Jacobs attributed to the 28-nanometer production oakley sunglasses issues, also was weaker than some analysts expected.

Qualcomm's stock slipped 3.5% to 64.60 in after-hours trading 2012 marc jacobs fashion sunglasses bestseller on sale DUPO5787 following the announcements.

Mr. Jacobs told analysts on a conference call that he expects "significant" improvement in chip supplies by the quarter ending in December. But he said supply constraints would limit revenue growth through the fiscal year, which ends in September.

Besides spending to address manufacturing constraints, Mr. Jacobs said, Qualcomm is stepping up investments associated with preparing its products for a coming monster beats 2012 version of Windows from Microsoft Corp.
