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!

How Do I Develop a Type of 12" Silicon Wafer Production?

Developing a 12" silicon wafer production process is complex and requires a robust infrastructure, specialized equipment, and strict process control to ensure wafer quality. Here’s a step-by-step outline of what’s typically involved:

1. Secure Facilities and Equipment

• Cleanroom Facility: Wafers are fabricated in Class 10 or higher cleanrooms to minimize contamination.
• Czochralski Process Equipment: To produce high-quality monocrystalline silicon ingots, which will be sliced into wafers.
• Slicing and Polishing Tools: Saws to slice ingots and chemical-mechanical polishing (CMP) equipment for flat, smooth surfaces.
• Oxidation and Etching Chambers: For oxide growth and surface treatment.
• Epitaxy Reactors: If adding epitaxial layers is required.

2. Develop the Growth Process for 12" Ingots

• Czochralski (CZ) Method: The CZ method is most common, pulling large-diameter ingots from molten silicon.
• Float-Zone Method: Alternatively, for ultra-pure wafers, though it’s less common in 12" production.
• Temperature Control and Seed Management: Precision in temperature and pulling rates ensures uniform crystal growth.

3. Implement Slicing and Shaping Techniques

• Wire Sawing: To slice 12" ingots accurately without causing structural defects.
• Grinding and Edge Shaping: Reduce micro-cracks and roughness, with edge rounding to prevent chipping.

4. Polishing and Surface Treatment

• Chemical Mechanical Polishing (CMP): Achieve the necessary flatness and mirror-like finish with CMP equipment.
• Surface Cleaning: Post-polish cleaning to remove any remaining particulates or chemical residues.

5. Testing and Quality Control

• Flatness and Thickness Uniformity: Using metrology tools to verify dimensional accuracy.
• Defect Density Inspection: Conduct optical or electron microscopy inspections for surface defects.
• Resistivity and Doping Level Testing: If wafers are doped, ensure uniformity through resistivity mapping.

6. Packaging and Shipping

• Contamination-Free Packaging: Specialized wafer carriers and cleanroom-compatible packaging for transport.

7. Process Optimization and Automation

• Invest in automation for high precision and yield improvement.
• Regularly optimize parameters such as ingot growth rates, polish pressure, and CMP slurry composition.

Establishing such a production process requires significant capital investment, expertise in semiconductor manufacturing, and adherence to stringent quality and safety standards. Developing the capability also often includes engaging with industry experts or consulting firms who specialize in large-scale semiconductor wafer production.

How much does a 12 inch wafer cost?

The cost of a 12 inch wafer can vary significantly depending on a number of factors, including the quality and purity of the material from which the wafer is made, the thickness of the wafer, and the number of wafers being purchased. In general, the price of a 12 inch wafer can range from a few hundred dollars to several thousand dollars, with higher-quality wafers typically costing more.

There are also several different grades of wafers available, each with its own set of characteristics and corresponding price range. For example, high-purity, single crystal wafers may be more expensive than lower-quality, multi-crystal wafers. Additionally, the price of a 12 inch wafer may vary depending on the quantity being purchased, with bulk discounts often available for large orders.

It is worth noting that the cost of a 12 inch wafer is only a small part of the overall cost of producing microelectronic devices. There are many other steps involved in the production process, including photolithography, etching, and deposition, which can significantly increase the overall cost of the final product.

12 Inch Silicon Wafer Applications

The 12 inch silicon wafer is a major improvement over the 8-inch silicon wafer. This larger silicon wafer is much more expensive to produce than an equivalent-sized 8-inch chip, but it also has a lot more benefits. Its wider width allows for tighter designs and higher yields, thereby improving profit margins. Unlike the 8-inch fab, a 12-inch fab requires much less capital expenditure to build and maintain.

Today, the 12 inch silicon wafer is the largest in the world. In the semiconductor industry, the 8-inch wafer is largely used for differentiated technologies, such as wireless communication chips, MCUs, and power chips. In contrast, the 12-inch silicon chip is used primarily for memory and other products, such as PCs and mobile phones. The 12-inch silicon wafer is the largest in the world, and the demand is increasing year-on-year.

The 12-inch silicon wafer is more efficient for precision processes, which make them more profitable for manufacturers. The downside of this, however, is that the 12-inch silicon wafer also leaves less space for applications of processes larger than 65nm, which leads to increased leakage. The capacity of the 8-inch fab is correlated to the price of the main raw material, the silicon. The supply is low and the price directly affects the downstream market.

There is a huge demand for 12 inch silicon wafers, and if you are not one of the first to purchase this type of silicon wafer, now is the time to buy. There are plenty of 12-inch companies in the market and prices are expected to drop over time. If you're in the market for a semiconductor chip, this is the time to make the switch. The 12-inch silicon fab is one of the best investments you can make.

In the meantime, the 12-inch silicon wafer market is growing. The newest fabs are expected to be ready for mass production by the end of this year. While the eight-inch silicon wafer has been the dominant technology in electronics for many years, the 12-inch version is gaining ground. Moreover, it is now easier to process large chips with this newer technology. Aside from this, it is cheaper to produce.

The 12-inch silicon wafer industry is a major player in the semiconductor industry. Its primary application areas are analog and discrete devices. Other applications are logic and digital processors. While both sizes are used in many fields, they are most commonly used for memory and power chips. And with their low-cost fixed-capacity, they are highly sought-after by many companies. The demand for 12 inch silicon wafers is growing rapidly in several fields, including automotive electronics.

Infineon, STMicroelectronics, and others are all experimenting with 12-inch silicon wafer production. They are aiming to meet the increasing demand for 8-inch silicon fabricated components and a 12-inch silicon wafer is an excellent choice. In addition, it is also the preferred size of the semiconductor industry. The industry is a competitive environment for the semiconductor industry, and it is important to ensure that a company is able to scale.

The eight-inch silicon wafer is a mature specialty-wafer process, which has strict tolerance limits and is used for a variety of applications. Because of the size of the semiconductor device, the eight-inch silicon fab's yields are lower, which is why 12 inch silicon-wafer production is more important for the semiconductor industry. They are not only cheaper to manufacture but also more flexible. They also have a higher yield than the 8-inch fabs.

Infineon is currently building four 12-inch silicon wafer fabs in Austria and plans to construct eight-inch wafers. Nexchip's first 12-inch fab started trial production in June 2017 and will enter mass production in early 2020. During the first quarter of 2018, the capacity of the first fab will reach 10,000 pcs per month and 40,000 pcs per month. By 2019, the 12 inch naysayers have already found their place in the semiconductor industry.

Silicon wafers are produced in U.S. fabs. They are standardized according to SEMI M1-0307 standards, which provide process repeatability and reliability. The current demand for a 12 inch silicon nipple is 5.43M/wpe. This is the maximum capacity for an 8-inch nipple silicon nipple. The nipple silicon niale is a great advancement in semiconductor technology and helps the semiconductor industry.

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."
