(Reuters) -Intel Corp will greatly expand its advanced chip manufacturing capacity as the new chief executive announced plans to spend as much as $20 billion to build two factories in Arizona and to open up its factories to outside customers.

The move by CEO Pat Gelsinger on Tuesday aims to restore Intel’s reputation after manufacturing delays sent shares plunging last year. The strategy will directly challenge the two other companies in the world that can make the most advanced chips, Taiwan’s Semiconductor Manufacturing Co Ltd (TSMC) and Korea’s Samsung Electronics Co Ltd.

And it will also aim to tilt a technological balance of power back to the United States and Europe as government leaders on both continents have become concerned about the risks of a concentration of chipmaking in Taiwan given tensions with China.

Intel shares rose 6.3% after the company disclosed its new strategy and full-year financial guidance for 2021. Some investors such as Third Point LLC had previously urged Intel to consider spinning off its costly chip manufacturing operations.

Intel said it expects $72 billion in revenue and adjusted earnings per share of $4.55, compared with analyst estimates of $72.9 billion and $4.77 per share, according to Refinitiv data. The company said it expects to spend $19 billion to $20 billion on capital expenditures.

Gelsinger said that 2021 forecast “reflects the industry-wide shortage” of some components such as substrates.

Intel is one of the few remaining semiconductor companies that both designs and manufactures its own chips. Rival chip designers such as Qualcomm Inc and Apple Inc rely on contract manufacturers.

In an interview with Reuters, Gelsinger said Intel has “fully resolved” its problems with its most recent manufacturing technology and is “all systems go” on chips for 2023. It now plans a massive manufacturing expansion.

That will include spending $20 billion on two new factories at an existing campus in Chandler, Arizona, that will create 3,000 permanent jobs. Intel will then work on future sites in the United States and in Europe, Gelsinger said.

Intel will use those factories to make its own chips but also open them to outside customers in what is called a “foundry” business model in the chip industry. Gelsinger said the new factories will focused on cutting-edge computing chip manufacturing, rather than the older or specialty technologies that some manufacturers such as GlobalFoundries specialize in.

“We are absolutely committed to leading process technology capabilities at scale for the industry, and for our customers,” Gelsigner said, adding that Intel has lined up customers for the new factories but could not disclose their names.

He did say on a webcast Tuesday that Amazon.com Inc, Cisco Systems Inc, Qualcomm Inc and Microsoft Corp support its efforts to offer chip manufacturing services.

The move is a direct challenge to TSMC and Samsung. The two have come to dominate semiconductor manufacturing business, moving its center of gravity from the United States, where much of the technology was once invented, to Asia, where more than two-thirds of advanced chips are now manufactured.

Gelsinger said Intel will aim to change that global balance by embracing the foundry business where it historically has been a minor player. Intel will offer chip customers the ability license out its own technological crown jewels – known as the x86 instruction set architecture – as well as offer to build chips based on technology from Arm Ltd or the emerging open source technology RISC-V, he said.

“We will be picking our next sites within the next year for U.S. and Europe,” he said.

Intel also announced plans for new research collaboration with IBM focused on computing chip and packaging technology.

But even as Intel jumps into competition with TSMC and Samsung, it also plans to become a larger customer of theirs by turning to them to make subcomponents of its chips called “tiles” to make some chips more cost-effectively.

“I’ll pick the best process technologies wherever they exist,” Gelsinger said. “I leverage internal and external supply chains. I’ll have the best cost structure. That combination of supply, products and costs, we think is a killer combination.”
