Development and Process Verification of Large-scale Microwave Plasma-enhanced Atomic Layer Deposition Equipment
Abstract: With the continuous development of semiconductor processes towards smaller sizes and higher precision, the research and development of atomic layer deposition (ALD) equipment has attracted increasing attention. This study combines microwave plasma sources with ALD technology, and through a systematic design approach, integrates a vacuum system, a microwave conduction system, a gas source input system, and a control system to successfully develop a large-size microwave plasma-enhanced ALD equipment. Microwave transmission simulation and optical emission spectrum detection results show that the equipment successfully achieved stable excitation of high-density plasma and generation of highly reactive free radicals. By adjusting the parameters of different microwave powers (400~1000 W) and different oxygen flow rates (10~1000 sccm), the equipment achieved a short single deposition cycle time of 14 s, a high oxygen free radical intensity value of 15769, and the deposited 8-inch alumina film exhibited a non-uniformity of 0.88%, a refractive index of 1.65 at 632.8 nm (with an extinction coefficient close to 0), and high dielectric constant and breakdown field strength of 9.3 and 23.6 MV/cm, respectively. The microwave plasma-enhanced atomic layer deposition equipment developed in this study exhibits excellent large-size wafer compatibility and high-quality thin film deposition capabilities, providing strong equipment support for applications such as high-performance dielectric layers, barrier layers, and packaging interface layers in advanced semiconductor processes and integrated circuit manufacturing.
Silicon Industry's bright-field defect inspection equipment has been successfully shipped to a leading wafer foundry.
The TB2000 bright-field defect inspection equipment shipped this time is designed for 28-14nm process nodes. It adopts a fully self-developed high-power broadband laser-excited plasma light source system and a deep ultraviolet high-throughput high-quality imaging system, combined with a high-line-frequency TDI camera and an ultra-precise high-speed motion platform. It also incorporates AI image processing algorithms and Design CA technology, which have the advantages of high resolution, high sensitivity, and high data throughput. It can meet the stringent requirements for wafer surface defect inspection in the chip manufacturing process, and help improve chip yield and reliability.
A clear strategic layout and the construction of end-to-end solutions.
Front-end defect inspection is a critical quality control step in semiconductor manufacturing . Bright-field defect detection technology, with its high sensitivity, high resolution, and wide defect detection range, has become a core technology for improving chip yield, reducing production costs, and driving process advancement. Tianzhun Technology continues to increase its R&D investment, achieving multiple breakthroughs in key technologies for semiconductor inspection equipment. This has resulted in a comprehensive product matrix of three bright-field defect detection systems (TB1100, TB1500, and TB2000) covering all process nodes, meeting the diverse defect detection needs of logic chips, memory chips, and other manufacturing processes.
In addition, through the strategy of "independent research and development + overseas mergers and acquisitions + ecosystem investment", Tianzhun Technology has overcome a number of core technologies and built a full-process intelligent quantity inspection solution that runs through wafer manufacturing, mask production and packaging testing.
The successful shipment of the TB2000 bright-field defect inspection equipment signifies that Tianzhun's technological strength in the high-end semiconductor equipment field has gained mainstream market recognition. In the future, Tianzhun will continue to adhere to independent innovation, accelerate the research and development of advanced process inspection equipment, build a more complete semiconductor equipment capability matrix, and provide core support for the domestic semiconductor industry to overcome "bottleneck" technological barriers and achieve high-quality development.
Yeah, overworking and labour abuses are rampant by Taiwanese companies and well documented. It’s no wonder they have the lowest birth rates (getting worse each year) on earth, lower than China, South Korea, Singapore, Japan). Crazy. At the rate they are going , they won’t be much people left in 40years from now there, China might just have an even easier time reunifying the island lol
Chinese Memory Makers Accelerate DDR5 Development, Reaching 8000 MT/s DRAM Speeds As They Near Samsung, SK Hynix & Micron Levels
CXMT, the biggest name in the Chinese DRAM market, is now accelerating its development, specifically targeted at DDR5 memory. But the story doesn't end at CXMT, other leading Chinese memory makers such as Jiahe Jinwei, recently powered Powev's Sniker-based , offering 64 GB capacities at 5600 MT/s speeds, a step up for Chinese AI firms looking to expand their capacities.
The same company is also offering DDR5 memory to meet domestic consumer demands, and as the production has ramped up (starting in 2024), these modules have only gotten better and better. CXMT debuted its 8000 MT/s DRAM modules in 16Gb and 24Gb capacities. While 32Gb DRAM has entered consumer segments, they come at a high cost. So China is now relying on domestically produced DRAM and memory, without the headache of external factors such as tariffs, supply constraints, and shipping rates.
What makes you think it is okay with a newbie to post crap from Zhihu here as a legit topic to talk about? You are not allowed to post on this thread for a week as punishment.
Feel free to read this thread carefully when you post again. If you bothered to do that you would have found out that YMTC tech has been licensed by Koreans for their future product. YMTC compared to CXMT has developed far more of the tech on its own.
How does foxconn treat their workers in India?
The most relevant questions would be where can consumers buy ymct and cxmt products? And when are ymct and cxmt IPO coming? The Chinese stock markets need a big rally in memory chips stocks.
