Has the United States achieved another “0” breakthrough? Is it related to chip technology again? Will Moore’s Law become a thing of the past?
When it comes to technological advancements, particularly in the field of computer technology, Moore’s Law has long been regarded as the golden rule. However, as technology approaches the limits of silicon-based transistors, will we reach the ceiling of Moore’s Law? This question now seems to have an unexpected answer.
MIT’s Revolutionary Breakthrough: Atomically Thin Transistor Technology Set to Revolutionize Chip Development
A research team at the Massachusetts Institute of Technology (MIT) has recently developed an atomically thin transistor based on molybdenum disulfide (MoS2) with Cryogenic Growth Process, which has the potential to bring revolutionary breakthroughs to chip technology.
Traditional semiconductor chips are made from bulky materials in a square 3D structure, and stacking multiple layers of transistors for more dense integration is very difficult.
Scientists have thus come up with the idea of using ultra-thin 2D materials to make semiconductor transistors, with each layer only three atoms thick, allowing for more powerful chips to be stacked.
However, growing 2D materials directly onto silicon CMOS wafers is a major challenge, as the process requires a temperature of approximately 600 degrees Celsius, which can damage the silicon transistors and circuits when heated above 400 degrees Celsius.
