I'd like to here more about laser drilling in glass that sounds cool. I got a christmas gift one year from an applied materials lab of a 3d scene inside a glass cube with thousands of dots. I was told they were created by the interaction of multiple lasers intersecting inside the glass cube. I never understood how that worked though.

"AMD has been granted a patent (12080632) that covers glass core substrate tech. Glass substrates will replace traditional organic substrates for multi-chiplet processors in the coming years. The patent not only means AMD has worked on appropriate technologies extensively but will enable the company to use glass substrates in the future without risks that a patent troll or competitors could sue it. "

Hi, friendly patent attorney here. Sorry, but this is all very much incorrect. Filing and/or receiving a patent does not necessarily mean a company has worked extensively on the underlying technology, as there is no requirement to build the technology out before filing a patent. More importantly, receiving a patent does not mean you cannot also infringe someone else's patent. A patent only grants the right to exclude others from practicing your patented invention, but does not even grant you the right to practice your own invention. People patent improvements to someone else's patented technology all the time, but doing so does not give them any right to practice the other person's existing patented technology.

Oh! Basically they're using multiple lasers of a frequency that can heat the glass, each one putting out a fraction of the power necessary to crack it. Where those lasers cross in the glass, together they have the energy in that spot to create a tiny crack, and that's what you see as the white dot. Do that a lot of times and you create an image.
At least, that's how it was explained to me.

This is not a big deal. SiC will overtake and eliminate the need to develop glass substrates, this is why AMD is granting access. Sell it now before it becomes obsolete..

This article is about the patent being to granted to AMD, not about them granting or leasing that IP to anyone else. AMD isn't selling anything here.

So why bother, other than feeding postdocs to hiring readiness, which seems important? MADish merit or participation points? Getting not docked $nation_set incentives?

All in favor of having 10s to 100s of npu right on the facial/fingerprint recognition camera/s, maybe throw a tdfs (time division fluorescence spectrometer) and other optical processing faculties that way.

Basically interference in action. If the beams don't add in phase there won't be enough energy to melt the glass.

Thanks! That method doesn't sound like it would work well for tiny tgv holes that go all the way through. I wonder how they'll make thousands of tiny holes with dimensional accuracy without breaking the whole thing.

Correct. There is also a cancer treatment that uses the same concept, with x-rays and another with gamma rays.

In both cases, as in the glass etching, each individual beam isn't enough to cause harm in their own, but the point where all the beams intersect will cause cellular disruption.

Extremely precise mapping, measuring, and targeting. It took them a decade to get from concept to safe application for using this method for cancer treatment.

This patent is likely to be challenged by Intel and other practitioners of TGV given the amount of prior art and open source research on the technology. I will go so far as to say it is a junk patent and unlikely to stand after litigation if it is ever asserted against competitors. AMD is being a bit of patent troll here, probably in a defensive move against Intel that has actually dine far more actual development of this technology as have others in the industry.

That said, I'm really enjoying the funny comments on this thread & offer a clue for the curious; this technique is actually well documented in open source as TGV (Through Glass Via) and is method to Laser enhance chemical etching to obtain higher differential etch rates in the Laser treated regions. Search it 😉

Hi. Friendly practitioner of the technology in question here. See my comment to the main thread, this is surely a defensive patent targeting Intel et al and basically junk. If, as I suggest, you search the subject you will find an amount of open source research for the process and also application that make be question the work of the USPO here. This is a classic defensive, junk patent, lets call it what it is.
