00:01-Introduction
It's a big, exciting Materion world, from the cell phones in your hand to the satellites orbiting the Earth, we are all around you. Come inside Materion to meet the people and hear the stories about how we bring it all to life every single day. Join us as we talk to our subject matter experts about topics and trends that are truly changing the world.

00:23 - Melissa
Hello, I am Melissa Mahl, your host for today's “Minds Over Materials” podcast. And I'm joined today by two technical experts, Mr. Jeff Hart, our AM Product Line Director, and Dr. David Van Heerden, Global Applications Engineering Manager who are here to talk with us about this relatively unknown material at the heart of 5G and IoT revolution. So Dave, let's get started with you. For our audience, why is 5G so important for everyone today?

00:54 - David
5G is essentially the new set of standards that have been set up by the FCC that are going to replace the 4G currently in your phone and are going to significantly change the way you interact with digital world. So at the moment, you can imagine if you're going to download a movie, it's going to take you a long time, it's going to take you know 5 to 10 minutes to download a movie, now imagine it at six seconds. Not just that, but you know, self-driving cars you've heard we've all heard about for years and years that's coming, all right? It depends very heavily on a very stable system, where in fact, you can't lose connection to the to the system, you can't lose connection to the servers, but that's what's going to be healthcare, that's also going to be your home from now on out. That's going to be the factory of tomorrow. It's huge. It's really going to change everything in our world, the digital world, the way we interact with it the next couple of years.

01:47 - Melissa
That sounds very fascinating. And I can't wait to learn more. So Jeff, before we get too far into this broadcast, can you tell our audience, what internet of things really is? Can you elaborate further on that?

02:00 - Jeff
The Internet of Things, is made up of billions of smart devices that are that range from miniscule chips to wearables, like a smartwatch to your household appliances, to large machines that run factories, and they all communicate with each other through the internet, it's essentially going to create a world in which everything is connected from, you know, your watch, being able to tell your doctor that you know you've got something wrong with your health condition, to you know, cars being able to talk on the road so that you can have autonomous driving to your refrigerator telling you while you're at the grocery store that you need milk and bread. So there's a lot of things that the Internet of Things, and I've heard it called the Internet of Everything, someday everything will be connected.

02:46-Melissa
Oh my goodness, that sounds amazing and scary all at the same time. So Jeff, before we dive into more detail about aluminum targets, can you introduce us briefly to materials, advanced materials business, and some of the solutions that you guys provide to Materion customers.

03:05-Jeff
Materion’s Advanced Materials group is made up of four business units. The company is comprised of premium targets, microelectronics packaging, advanced chemicals, and large area targets. The aluminum scandium targets that we're talking about today are part of the premium targets group. The premium targets group really focuses on making hard-to-make niche materials that make devices that enable 5G to work. We also have precursors for ALD, we have the ability to refine gold, to do shield cleaning, precision parts cleaning, and do with the whole value chain for our customers. The advanced chemicals group does a multitude of inorganic chemicals. So if it's on the periodic table, there's a good chance that Materion can provide it for you.

04:02-Melissa
Wonderful, thank you for that explanation. So Dave, let's transition over to you. Can you tell us what exactly an aluminum scandium target is?

04:11-David
So aluminum scandium sputtering target is, imagine in your mind a disc somewhere between 12 and 16 inches in diameter, pretty thin, actually a quarter of an inch thick, okay. And it's used in a sputtering tool to actually deposit very thin forms of material onto silicon wafers that you've heard of previously. And the material itself is an array that's made by casting, metallic casting, of material. It's highly uniform, very high purity, very low impurity levels and very heavily engineered so that when I put this in my sputter chamber, I try and deposit my form, that the formula The form is very character, very consistent wafer to wafer and has exactly the same chemistry exact same stresses in it exactly as compounds are put down on it. So it's a highly engineered, thin piece of metal that's actually used for making and was used to do is actually to deposit not scandium aluminum but actually scandium aluminum nitride, which is really cool material because actually piezoelectric. So it and this piezoelectric is really what's at the heart of those folders we talked about earlier. So the fact that the target is a very, very simple piece of heavily engineered metallurgical material that's used to deposit very complex forms.

05:30-Melissa
So what makes Materion’s stand out from other aluminum scandium targets manufacturers in the marketplace?

05:37-David
So as I said, the material itself the basic metallurgy, and it's literally the scandium and aluminum, it's pretty much as simple as it gets in metallurgy a binary system. But in fact, what what's hidden behind that is a whole lot of very complex engineering, to create the microstructure and the chemistry and all that stuff in the target to give you the correct form properties. So two parts about that, the first part is that it's very heavily engineered with our group about two, I think, seven or eight engineers to work on this for six to seven years to actually make this material. Okay. The second thing is, even when you make it, it's not obvious, it's going to work on the wafer. So what we've actually done is we've partnered with our customers, and we will make it they'll test it, and we'll work together to actually create a material which is uniquely tailored to their particular processes. Okay. And then, in addition to that, it has to run on a spring tool in very high volume, consistent prototype, and also that was developed in conjunction. So it was basically combining a bunch of very smart PhD engineers, with the engineers and the cast on our customers to make these unique, detailed products that allow them to make these foams.

06:47-Melissa
Wonderful. Thank you for that further explanation. So David, how did Materion Advanced Materials team respond to these challenges, and what's so special about our products?

06:58-David
So the way we the way we respond to challenges, most of the people in Materion and sit in this division tend to be metallurgists, material scientists, most of the people, the fabs, as you can imagine are actually physicists and people that run sputtering tools, both enormously smart people, beginning to talk to a common language, to be able to say, if we do this to our target, it does this to your phone level, most of our customers have never really thought about there being a lot of engineering in the targets. So actually sitting down with their engineers, explaining what targets do, and then working with them to understand if I do this to my target – it does this in your phone, was really the magic part of being able to do it. And that was what I mean, we partner I think better than anybody at being able to do this with our customers. And that's allowed us to allow them to very rapidly develop product, which is a great advantage to them to get the product, the properties of the forms they wanted consistently, first to develop products, processes around those products, we could deliver the targets in high volume.

07:56-Melissa
Thank you for that, so very much. So Jeff, coming back over to you, can you give us some insight into what has been what's next for advanced materials targeting?

08:07-Jeff
Yeah, absolutely. So smaller, faster devices, are really pushing the limits of materials today. So as you can imagine, these devices get smaller and smaller. The Next Generation semiconductor devices are talking about having, you know, a three nanometer line width. So three nanometers of, you know, much smaller than the diameter of a human hair. And, and so the materials are being pushed to their limits. So we're working on a lot of next generation high purity materials to be able to handle these requirements is and in addition to that, there are also is more and more things go into the Internet of Things, you need to be able to store and quickly retrieve data from these internet devices. A lot of our focus right now has been on advanced memory solutions for things like an STT-RAM or a PC-RAM that are next generation memory devices.

09:06-Melissa
Can you give us a success story for what you were just talking to us about?

09:11-Jeff
I have a good example. Materion was approached a couple years ago by a large wireless company, looking to make bulk acoustic wave filters out of compositions and tolerances that none of the rest of the industry had even considered. They chose to work with us because of our excellent reputation and our willingness to work on challenging materials that were at the cutting edge of the industry. We worked intensively on optimizing our materials for their processes and designs and develop a product with them that helped them win multiple design ends at end customers where they're currently producing and high volume. And when I say high volume, I mean they're making billions of devices. We still work closely with them, and we're developing with them the next two generations of wireless products together.

10:00-Melissa
Wow. I mean, like I said earlier, this sounds really scary all at the same time is very fascinating. I'm thinking about things that we have today, right? I'm aware of watches is wearables, and obviously, our cell phones, but you guys are talking about businesses and healthcare units of the future. So do you actually have customers right now that are developing those applications today? Or is this just an idea that they want to move towards?

10:30-Jeff
Now? That's a great question. We have customers that are currently today, making some of these devices making some of these connections possible. And then there's a lot of the next generation products that are going to make it faster, better, more reliable. For doctors to make better decisions for autonomous cars to make the right call, should I break? Should I speed up? You know, do I need to avoid an oncoming person in the road? So there's a lot of lot of things you think about that. You know, if you really want smart devices that that are going to truly be the heart of what our future is. They certainly need to be able to be extremely fast and be able to make the same decisions that a human would.
