These production years are targets, and in our opinion, further delays from at least 2 of these players are likely.ĢD materials are often grown via Chemical Vapor Deposition (CVD), though more recent efforts also include Atomic Layer Deposition (ALD). TSMC has GAA with their N2 process node in 2025 or 2026. Intel has GAA on its roadmap with 20A process node which is manufacturing-ready in 2024 with products shipping in volume in 2025. Due to issues with yield, high-volume chips from Samsung’s 3nm GAP are expected in 2024. In 2022, Samsung began using GAA in its 3nm process. The width of each nanosheet, as well the number of nanosheets in each transistor can be varied, allowing for custom designs. This increases the drive current and overall performance of transistors even further. GAA uses stacked horizontal “nanosheets”, so that the gate surrounds the channel on all 4 sides. These next-generation transistors are known as “Gate-All-Around” transistors, or GAAFETs. Transistors are essentially switches for electrical current a voltage that is applied to its “gate” can cause a current to flow in the channel between its “source” and “drain.” Each transistor can turn on or off, corresponding to a “1” or “0.” Driven by Moore’s Law scaling and improvements in CMOS process technology, modern computing chips do this on the scale of billions and even trillions.Ĭonducts the maximum amount of current when turned onĭoesn’t allow any current to flow when turned offĭue to the limit of how thin/high fins can be made as well as how many fins can be placed side by side, another evolution of the transistor is currently underway in the industry. The fundamental component of any chip is the transistor, which recently celebrated its 75 th birthday. Also thank you to Sanders at ASML who created some content used in this report aswell. This report was written in conjunction with Shan Kutagulla & Anand Chamarthy of Lab 91, Inc, an Austin, TX-based semiconductor equipment company developing the process technology and equipment required for integrating 2D materials in semiconductor fabrication.
