🔍 What Did They Find & Why It Matters?

💡 The Big Idea

Today’s chips rely on silicon transistors—tiny switches that power your devices. But as chips get smaller and faster, silicon is reaching its physical limits. Scientists worldwide are searching for alternatives.

Enter 2D semiconductors—materials that are just a few atoms thick!

CDimension’s innovation lies in using a low-temperature process (200°C) to grow molybdenum disulfide (MoS₂) directly on silicon. This solves a major problem—normally, growing such materials requires temperatures over 1000°C, which would damage the chip.

This opens the door to layering 2D materials on top of current silicon chips, leading to 3D chips with better performance and less power usage.

🧪 A Simple Way to Understand It

Imagine you want to add a second floor to a house made of jelly (fragile silicon). Normally, building on top would melt the house! But CDimension found a way to gently add that second floor without melting the base. That’s how game-changing their low-temp growth technique is.

🗣️ What the Researchers Say

“Most people still think of 2D semiconductors as lab-only materials,” says Jiadi Zhu, CEO and co-founder of CDimension. “But we’ve solved big problems like making uniform 2D layers, ensuring good performance, and making it work with existing chip-making tech.”

🔧 What Else Did They Do?

CDimension is already shipping silicon wafers with 2D materials for chipmakers like Intel, Samsung, and TSMC to test. These materials don’t just save energy—they may allow devices to run on half the voltage.

In fact, their tests show that MoS₂ transistors can use 1/1000th the energy of today’s silicon ones!

They’re also working with tungsten diselenide (p-type) and hexagonal boron nitride (insulator) to complete the puzzle for future CMOS (logic) chips.
