Samsung virtually introduced EUV pellicle to the foundry process details
Samsung has decided to significantly expand the scope of application of the pellicle, which it has decided to introduce in the semiconductor extreme ultraviolet (EUV) exposure process from 2023. The original plan, which was only used for manufacturing large chips such as CPUs and GPUs, was changed, and the pellicle was decided to be applied to virtually all chip production.
According to the info, Choi Si-young, president of the foundry division, recently received a report on the pellicle application plan for the EUV process and was directly instructed to greatly expand the pellicle application range compared to the original plan.
Initially, Samsung’s foundry division planned to apply the pellicle to the EUV process from 2023, but in the form of ‘one shot, one dies’. ‘1 shot, 1 die’ means that one chip is printed with one mask in the exposure process.

This is not comparable to masks costing hundreds of millions of won per piece, but considering that the price of pellicles is high enough to reach 90 million to 100 million won per piece. Considering the manufacturing cost, the idea was to apply first to large-sized chips and to operate small-sized chips without a pellicle as before and then apply them sequentially.
In EUV equipment, the loss of light source is large because light has to come in once and then go out after being reflected again. To minimize this, a transmittance of 90% or more and a thin pellicle of 50-nanometer class are required.
In the meantime, Samsung has been producing semiconductors without a pellicle even though the mask can be exposed to dust in the EUV process. This is because a pellicle having a transmittance of 90% or more have not been developed so far.
However, as the development of pellicles with a transmittance of more than 90% has become visible recently, it has been decided to apply them to the process from 2023. The industry predicts that Samsung will use the EUV equipment maker ASML Alliance (ASML/development + Terradyne/membrane manufacturing + Mitsui Chemicals/production) Pellicle MK4.0 (transmittance 90%) or higher grade products.
As Samsung has decided to virtually fully introduce pellicle to the EUV process, related partners are also expected to benefit. Companies related to domestic EUV process technology include FST (Pellicle, pellicle automatic mounting equipment), S&S Tech (Pellicle, EUV blank mask), and Device ENG (Foop cleaning equipment for EUV, photomask cleaning equipment for EUV).
Samsung’s April 2024 update is reportedly bricking Galaxy Z Fold 3. A user reported on the Korean version of Samsung’s community that this smartphone was stuck in recovery mode after triggering the installation of the F926NKSU2HXD2 firmware.
The problem seems limited as I haven’t found many reports regarding the same. At the same time, the comments section of the source post also lacks similar feedback from consumers. Still, I recommend you not to install the HXD2 firmware on your Galaxy.
Samsung has recently launched Samsung Wallet in its home ground. We’ve seen a heavy number of Samsung Pay users switching to Wallet for advanced payments and mobile ID features. Notably, the firmware update also brought Samsung Wallet Mobile ID integration for the Fold 3.
Apart from the Wallet upgrade, the firmware brings the April 2024 security patch. Samsung may have also released HXD2 to the Galaxy Z Flip 3 in South Korea. The same firmware was started rolling out to the Galaxy Z Flip 4, however, there are no reports from consumers in the community.
While the smartphone is stuck in recovery mode, the only way left is to wipe the data. Wiping data will lead the user to lose access to all the personal data that was not backed up. Also, there will be a lot of hurdles after manually resetting the device such as logging in via the trusted device.
We will update you on the matter!

The US variant of Samsung Galaxy Z Flip 6 will be equipped with a Snapdragon 8 Gen 3 processor. There were reports that Samsung may expand the Exynos chipset to its foldable lineup, which doesn’t seem to be happening, at least in the United States.
Recently, Samsung Galaxy Z Flip 6 US variant was spotted on Geekbench with Snapdragon chip. It isn’t surprising as the company is following its conventional chipset strategy. We expect that it will be the same chipset used in the Galaxy S24 Ultra, the Snapdragon 8 Gen 3 for Galaxy.
The Flip 6 smartphone scored 15084 points on Geekbench’s GPU test. Due to its foldable form factor, the device may miss a Galaxy S24-like larger cooling technology. Still, its impressive 15000+ points in the GPU test indicates that Samsung has greatly optimized the software.
The company still has three months remaining in the launch event. More performance improvements will likely be achieved before the Unpacked. The South Korean tech giant will likely unveil the next-gen foldable phones in mid-July.
This year, the Galaxy Z Fold 6 Ultra would join the standard Galaxy Z Fold 6 and the Galaxy Z Flip 6. In addition, an affordable variant of Fan Edition branding is also in development. However, the cheaper foldable would miss some pro-grade specs to maintain the price.
