Cerebras Sytems Fabricates a 12 Inch Wafer to Contain 1.2 Trillion Transisitors

1.2 Trillion Transistors on on chip!   Cerebras sytems in conjunction the Department of Energy’s (DOE) National Energy Technology Laboratory today announced that the Cerebrs CS-1 system is greater than 10,000 times faster than the most powerful graphics processing unit (GPU) found in today’s computers.  The speed of the CS-1 system will now be able to train Artificial Intelligence neural networks in minutes instead of months!

Using a 12-inch diameter silicon wafer to make a single massive chip. Dubbed a core.  

Then the chip is interconnected to other cores in an efficient manner.   The 12 inch wafer can be sliced into hundreds of smaller chips for use in electronics. All the cores can work together and function as one transistor at very high speeds.

Below is a short history of transistor growth.


Year             Transistors               Company
1971             2,300                          Intel
2020            54 Billion                  Nvidia
2020            1.2 Trillion                Cerebras


Cerebras claims that their CS-1 is 200 times faster than the Joule supercomputer which costs tens of millions of dollars to build, with 84,000 CPU cores spread over dozens of racks, and it consumes 450 kilowatts of power. Cerebras costs several million dollars and uses 20 kilowatts of power.

Cerebras fabricates a silicon wafer with 400,000 AI cores on it instead of slicing that wafer into individual chips. This design is considered unique in the semiconductor industry. But this new design makes processing data much more efficient by placing the processor and memory closer to each other with many bandwidth to connect them.

You can't name the industry that the CS-1 won't affect!

12 Inch Silicon Wafer Applications

A metamaterial is an artificial material that has properties that don't exist in nature. It's a material that has been designed to have properties that are impossible for nature to create. The key word here is design. In order to create a metamaterial, you have to use your intelligence to design it, and then you have to use your intelligence to make it. A metamaterial has properties that don't exist in nature. These properties are created by the way the metamaterial is designed, and the way the metamaterial is made. The properties of a metamaterial are determined by its design and its manufacturing process. The word "metamaterial" comes from two words: "meta" means "above" or "beyond", and "material" means "matter" or "material". So, a metamaterial is a material that is above or beyond natural matter. Metamaterials are artificial materials made by intelligent beings with intelligence. They are not natural materials made by unintelligent beings without intelligence. Metamaterials are manmade, not God made.

12 Inch CMOS

A fifth grader asked me to explain this concept: The implementation of polarization controlling components enables additional functionalities of short-wave infrared (SWIR) imagers. The high-performance and mass-producible polarization controller based on Si metasurface is in high demand for the next-generation SWIR imaging system. In this work, we report the first demonstration of all-Si metasurface based polarizing bandpass filters (PBFs) on 12-inch wafers. The PBF achieves a polarization extinction ratio of above 10 dB in power within the passbands. Using the complementary metal-oxide-semiconductor (CMOS) compatible 193nm ArF deep ultra-violet (DUV) immersion lithography and inductively coupled plasma (ICP) etch processing line, a device yield of 82% is achieved."
