What was the revenue growth rate for the Electronic Chemicals business in the 2021-Q1 quarter 
vanced logic nodes and those advanced foundry nodes; when those start really picking up, we get the benefits of that growth.
So, we're continuing to build on our leadership positions for slurry, and we saw that strength this quarter. We also talked about, in our prepared remarks, that China was very strong. You would expect Korea to be strong with stronger memory backdrop. We also talked about growth in China, which is mostly logic/foundry and what we consider legacy. We have very strong positions in China, and we see continued growth ahead in the next several quarters. And, of course, China is a very important geography for the semiconductor industry, including us.

Got it. Super helpful. And then as a quick follow-up, on the Electronic Chemicals business, I was a little surprised by how muted growth was in the segment. Yes. Your biggest customer in North America, they've got great momentum across, I guess, primarily the PC business and potentially in servers going forward. You've spoken to weakness in lagging edge on prior calls as a headwind. And if anything, the lagging edge seems to be recovering pretty nicely across the automotive and industrial end markets. So, curious what the puts and takes were in the electronic chemicals business in December. And I guess, more importantly, what's the outlook into March and June?
David H. Li -- President and Chief Executive Officer
Yes. Thanks, Toshiya. I think you've got a good handle on that business. Obviously, the dynamics are a bit different than slurries and pads, where we sell to a number of different customers. This is a solid profitable business, but it's very regional. And our participation -- the customer concentration and where we participate is much more concentrated. So, it's U.S., Europe, and Southeast Asia. So, the quarter -- on a quarterly basis, there will be more puts and takes just by the order patterns of specific customers.
Also, just by where we participate, we're not going to get as much lift from a memory sort of strength or increase in utilization. I think longer term, we continue to make improvements in the business that we think are going to differentiate ourselves -- further differentiate ourselves from our competitors from a quality and supply chain perspective. And we do expect, although we don't give specific guidance for the next quarter, we would expect it to grow year-over-year. So, it's got some different dynamics quarter-by-quarter. It's going to have some puts and takes, but it's really much more concentrated, much more regional. But we think it's going to grow year-over-year.

Hi. Good morning, everyone. I was wondering if you can give some additional details on the new business wins that you referred to in the CMP pads business. Is this more of an expansion of positions with existing customers or are you winning new customers? Maybe just give us some thoughts there?
David H. Li -- President and Chief Executive Officer
Thanks, Mike. And again, this is kind of a continuation of the narrative we've been talking about for a while, which is we're really excited about this business and we continue to see wins. We talked about in the prepared remarks, customer wins in leading foundry and leading memory applications. And so, what we saw this quarter and what we see going forward is the ramp-up of those wins. Sometimes, they take time, especially if they're at the leading edge.
But when we think about and we look at the pipeline of opportunities, it's really exciting because we're seeing strength and really, really compelling interest from customers across different segments. So, I think the recent wins are with customers that are both in foundry and memory, the
vanced logic nodes and those advanced foundry nodes; when those start really picking up, we get the benefits of that growth.
