Huge News~!! The PR is not showing up via the link on the website, UGH. It's the small details sometimes

The announcement that Lightwave Logic (LWLG) is releasing Version 1.1 of their BEOL (Back-End-of-Line) process to foundries is a significant technical and commercial milestone. In semiconductor manufacturing, the BEOL is where the magic of "connection" happens, and for LWLG, this update signals that their polymer technology is moving from a laboratory curiosity to a standardized industrial component.

Here is the breakdown of why Version 1.1 matters for the company and its investors.

1. What is the BEOL Process?
To understand the significance, you have to look at how a chip is built.

FEOL (Front-End): This is the base layer where the transistors are etched into the silicon.

BEOL (Back-End): This is the "wiring" stage. After the transistors are done, layers of metal and dielectric materials are added on top to connect those transistors together and to the outside world.

Why this matters for LWLG: Their electro-optic polymers are integrated during this BEOL stage. Releasing a "Process Version" means LWLG has codified the exact recipe (temperatures, chemical exposure, and timing) that a foundry like GlobalFoundries or Tower needs to use to add the polymer layer without damaging the sensitive transistors underneath.

2. The Significance of "Version 1.1"
In the world of Process Design Kits (PDKs), a version jump (from 1.0 to 1.1) usually represents Stability and Optimization:

Yield Improvement: Version 1.0 is often about "can we make it?" Version 1.1 is about "can we make it reliably?" This update likely includes data from the initial 2026 validation tape-outs, reflecting adjustments that improve the percentage of working chips on a wafer.

Performance "Hardening": This version likely tightens the specs on the V-pi (drive voltage) and Bandwidth. For an end user like Nvidia, a 1.1 release provides more certainty that the performance seen in a lab will be replicated in mass production.

Design Rule Checks (DRC): Version 1.1 usually gives chip designers more refined "rules." Think of it as a more accurate blueprint that prevents designers from placing components too close together in a way that would cause the polymer to degrade.

3. Impact on the Foundries (GF and Tower)
By releasing this to the foundries, LWLG is essentially "handing over the keys" to the production line.

Foundry Confidence: Foundries do not accept process updates unless they are proven to be "CMOS compatible." This release confirms that LWLG’s polymer can withstand the standard heat and chemical cycles of a Tier-1 foundry without contaminating their multi-billion dollar machines.

Customer Accessibility: Now that Version 1.1 is in the foundry’s hands, any customer using the GlobalFoundries or Tower PH18 PDK can update their design files to the latest specs. This lowers the barrier for "Stage 3" partners to move into "Stage 4" (Initial Production).

The Timeline: This suggests that the 2026 tape-outs are providing the necessary data to freeze the design for commercial 800G and 1.6T transceivers.

In short, Version 1.1 is the transition from an "experiment" to a "product." It is the technical equivalent of moving from a hand-built prototype car to a set of blueprints that a high-volume factory can actually use.

Super news!! We are soooo close! Stage 4 Here we are!!

This PDK 1.1 update is a solid step toward de-risking high-volume production compatibility. It reinforces LWLG’s positioning in the silicon photonics ecosystem for AI-driven optical connectivity. Watch the Q1 2026 earnings call (May 13, 2026) for more details on timelines, foundry progress, and customer traction.

To the average person they will not have a clue what BEOL, Polling, ALD Encapsulation, or what a PDK is so let me give it a 101 shot. (Oh why are ketchup bottles showing up at random spots on my computer, lol?)

First and most important this is really all they need to understand:

"These enhancements are designed to further streamline integration into silicon photonics platforms and accelerate adoption within high-volume manufacturing environments."

BEOL Back end of line, after all the electronics on the chip are done, the foundry can add the optical components directly to the chip at the foundry. Not in a lab, not on the bench high volume production, get it?

Wafer scale polling means applying voltage to line up the north and south poles of the chromophore so the signal can pass from one to another like a bunch of refrigerator magnets, again this is now done at wafer scale not in the foundry, I'm from the days of when they had to cut up the wafer (dice it) and pole the chips one at a time on the bench in the lab. Again for high volume production.

Encapsulation this is where they spray a light coating of hairspray like material on the chip to prevent oxygen from F'ing with it. Again this is done in the foundry and eliminates the need for a "gold box" to protect it. Lightwave has the patent on this for polymers, the foundries have been doing this on silicon for years in the foundry and are already familiar with it.

PDK is what a customer can use to select options for a foundry to place on a chip. Like ordering electric headrests on your car. Funny I got in my wifes car the other day and the headrests went crazy up and down, I said this is ridiculous, I remember when cars didn't even have them and everyone walked around with neck braces.

Yes, this is big announcement and I like the Version 1.1 thing. Again, most that read it will not totally understand what it is saying these things for years are what the shorts said could not be done and why they laid down their bets, for years they posted ad hominem on here gas lighting this board by saying that it could never be done.

This get together thing is coming together ordered up a buffet for the folks attending and will post more detail as the event draws closer. While I don't mind springing for the grub I'm doing a cash bar.

Again, if you want to attend send an email to [e-mail] currently at about 40 but we all know how that goes. Casual dress for real people.
