What is the company's revenue outlook for the WFE market in 2021, assuming all required licenses from customers are obtained
ou look out, say, three to five years. So can you just kind of talk about what's happening in logic?
Gary Dickerson -- President and Chief Executive Officer
Thanks for the question, Tim. So what I would say, I meet these CEOs and R&D leaders for leading foundry and logic on a very regular basis, actually more often now than I did before the pandemic because we're doing all of this virtual. I deeply believe -- and you can see even this week, there was one of our leading customers talking about how they're driving their technology road maps going forward. And it's really around the five elements that we've been talking about: the new structures; new chip architectures; everybody is designing their own application-specific chips; new materials; new ways to shrink.
I've talked about packaging and the growth there, but I think we're just in a tremendous position. And when you think about what's going to drive power performance and cost going forward, there's no question, it's about these new structures and these new materials. And when you look at really all of the different markets, you talked about the new transistor structures going forward, whether -- people call gate-all-around or nano sheets or also the wiring, the resistance in the wiring, there's tremendous focus in those areas because that is really what enables power and performance going forward. So we're just in a really tremendous position.
When you think about the materials that are needed to create those nano sheets or the wiring or 3D DRAM or any of those big inflections that are going forward in the future, we just have, by far, the best portfolio of materials that creates those structures. Then you think about shaping the structures. We have strength in conductor etch. We're -- we've certainly had a strong position in memory.
We're growing in foundry/logic. You'll see our share continue to grow there. Shaping with the Selectra product is also really important for nano sheets and for other new structures, the modification of those different structures and also accelerating the time to market. I talked about the synergies with our PDC and especially our e-beam business.
When I'm building this new transistor, if I can see the materials -- residual materials inside that structure as I'm driving the R&D versus having to cross-section one particular transistor and look inside that, their learning rates go up by orders of magnitude. So those unique imaging capabilities, combined with the unique capabilities in creating and shaping and modifying those structures, again, I just -- if you look at what's being presented by our leading customers, even this week, you'll see exactly aligns to this new playbook and enabling capabilities for Applied. So again, I've never been more excited about our opportunities to enable the road map.

Thank you. Our next question comes from the line of Joe Quatrochi with Wells Fargo. Your line is now open.
Joe Quatrochi -- Wells Fargo Securities -- Analsyt
Yeah. Thanks for taking the question. I was curious in your WFE outlook for this year, what's your assumption around domestic China? And does your WFE outlook for this year include the assumption that we don't see any license from customers that are required by the government right now?
Dan Durn -- Chief Financial Officer
Yeah. Joe, thanks for your question. So from a domestic China standpoint, we think we ended the year 2020 around $10 billion. We think we're up a few billion off of that level.
So we'll see this year what we've been seeing for several years now, which is slow, steady ecosystem development. You're going to see some investment in technology road maps and still some pretty modest capacity additions that sit behind those technology road maps. And then from a licensing standpoint, just given where we sit in the process, we think it's prudent to forecast and guide revenue and market sizing, assuming the licenses do not come through. And when we receive the licenses, then we'll adjust the expectations.
I would expect revenue to go up, and I would expect the market siz
