Huali Chuang Science has developed the world's smallest optical six-dimensional MEMs force sensor and completed a multi-million yuan A+ round of financing​

Recently, Huali Chuang Science announced that it has completed a multi-million-yuan A+ round of financing, which was exclusively invested by Polylite, a leading listed company in the field of metal 3D printing. It is disclosed that the funds raised in this round of financing will be used to deeply explore high-performance optical multimodal sensing technology, combined with the advantages of metal 3D printing technology in product lightweighting, special material application, mass production cost, etc., to provide a powerful and cost-effective six-dimensional force sensing solution for the embodied intelligence field represented by humanoid robots, and promote the development of the embodied intelligence industry.
Huali Chuang Science has developed a "head-to-toe" six-dimensional force sensing solution. In response to the gap in humanoid robot knuckle force perception, in June 2024, Huali Chuang Science released the world's smallest known optical six-dimensional force sensor Photon Finger , which for the first time miniaturized the size of multi-dimensional force sensors to the millimeter level, overcoming the miniaturization problem of six-dimensional force sensors. At the same time, with the support of metal 3D printing, the cost has been greatly reduced, and the products have been used in companies such as Tencent, Qiangnao Technology, and RoboSense. In view of the high performance, lightweight, and easy integration required for the six-dimensional force sensing of the humanoid robot wrist, in December 24, the six-dimensional force sensor PhotonR40 with a central through-hole structure was launched, which greatly reduced the difficulty of integrating the force perception of the humanoid robot wrist joint. This product used metal 3D printing technology for the first time to complete the mass production of the core structure, and has been used by many customers.

Impact of even aberrations on alignment accuracy in image-processing-based systems​

Abstract​

The alignment system is a critical sensor for ensuring the overlay performance of lithographic tools, with lens aberrations playing a significant role in determining alignment accuracy. This study investigates the influence of aberrations on alignment accuracy through both simulations and experiments. The findings reveal that even aberrations lead to variations in the sensitivity of odd aberration-induced misalignment. These variations are explained by analyzing the asymmetry of the optical system’s impulse response function. Sensitivity curves were generated by numerical simulation using Hyperlith and validated through experimental measurements. The results refine the understanding of the impact of lens aberrations on alignment accuracy. The proposed sensitivity curve offers a foundation for optimizing error-correction models, ultimately improving alignment accuracy in lithographic processes.

55 billion yuan Hefei 8.6-generation OLED project first ordered equipment​

​

Hefei Guoxian, a subsidiary of Visionox, has started construction of its 8.6th generation organic light-emitting diode (OLED) production line.​

Ion doping equipment is a device that injects ions in the form of gas to improve the characteristics of low-temperature polycrystalline silicon (LTPS) and low-temperature polycrystalline silicon oxide (LTPO) thin-film transistor (TFT) devices. This is one of the core equipment of OLED process.

This is the first time that Hefei Guoxian, a subsidiary of Visionox, has ordered 8.6-generation OLED-related equipment.

It is understood that the total investment of the 8.6-generation AMOLED production line project of Hefei Guoxian Technology Co., Ltd. is 55 billion yuan, with a designed production capacity of 32,000 glass substrates per month (size 2290mm×2620mm), which can produce larger-sized AMOLED panels, covering multi-size application fields such as tablets, laptops, cars, and displays.

This high-generation AMOLED production line has been upgraded in terms of technology, size, efficiency, and application. It is the world's first application of precision metal mask-free technology solutions, which can greatly improve the cutting efficiency and economy of medium and large-sized OLED products. It will drive the update and iteration of downstream terminals through technological upgrades, further tap the growth potential of AMOLED, and help Hefei move towards the "World Display Capital", reshaping the global AMOLED panel supply landscape.

It is understood that Hefei Guoxian Technology Co., Ltd. ("Hefei Guoxian") is responsible for the investment, construction and operation of the production line. The company will be funded by Visionox and Hefei Investment Platform. Visionox and Hefei Guoxian have worked together in the transformation of innovative technologies to create a high-generation AMOLED production line with leading technology, strong compatibility and wide coverage. The production line brings ViP, LTPO+, COE, Tandem and other technical upgrades "black technology" to meet the needs of medium and large-sized OLED panel products for low power consumption, high brightness and long life.

Piotech Bonding tools.

I was wondering, the 294L was two 150L and 140L Bonded together. So I asked the AI (kimi.ai and DeepSeek), is it due to equipment limitation (No access to LAM Etchers) or is it industry norm to join two Decks (150L and 140L decks) to achieve a tall 294L.

Apparently, most of industry, SK Hynix, Samsung, just grows the Layer without Joining two Decks. But due to limitation YMTC chose this path to bond two Decks, and it has an advantage of achieving higher Density of Memory (20GB/mm2) but is much harder to do so and more prone to defects during Hybrid bonding.

If anyone has more insight on this topic do share. My main concern here is how far AMEC/Naura etching has come compared to leading players like LAM

Yin Zhiyao, Chairman of AMEC: Our etching machine has achieved the goal of processing one atom accurately every time (Core Things) Mr. Yin said that AMEC's laboratory technology can achieve an accuracy of 0.02nm, while a silicon atom is 0.25nm, which means it can process at the atomic scale. It is really amazing, and may surpass American companies!

i don't think so, you can find better information that this.. AMEC chairman itself said this.. Etching Empire has completed.

No necessary, Xtacking showed that hybrid bonding technology is maturing fast and this proves that is ready for prime time.
