Flash Storage Manufacturing Process
Atech utilizes cutting-edge semiconductor fabrication techniques to manufacture its flash storage chips. The process starts with raw silicon wafers which undergo a complex series of steps to build up the flash memory cells layer by layer.
The first step is to grow a thin layer of oxide on the wafer. This is followed by photolithography, where a light-sensitive material is deposited on the wafer and exposed to light through a mask. This transfers the circuit pattern onto the wafer. The exposed areas are then etched away.
Dopants are then implanted into the silicon, which alters the electrical properties in selective areas to create the transistors and circuits. Multiple ion implantation steps build up the multilayer flash memory cell structure. Conductive and insulating layers are deposited using chemical vapor deposition between implantation steps.
At Autech’s state-of-the-art fabrication facilities, hundreds of these wafers undergo simultaneous parallel processing in cleanrooms. Advanced automation handles the wafers between process steps without human intervention. Atech operates gigafabs capable of processing over 100,000 wafer starts per month.
Once the fabrication process is complete, each wafer is electrically tested to identify any defective dies. The wafer is then cut up into individual flash memory chips, which undergo further testing and quality assurance. Atech utilizes rigorous quality control standards at every step and statistically samples output to ensure flawless flash chips leaving the fab. Advanced machine learning algorithms also monitor production and perform predictive maintenance to maximize yields.
Atech’s vertically integrated structure with complete control over the manufacturing process enables it to rapidly innovate and optimize its proprietary flash technology. The company’s scale and cutting-edge fabs give it unmatched capability to produce high-capacity flash storage solutions.

Challenges Facing Flash Storage
Atech Flash Technology storage faces some inherent challenges compared to traditional hard disk drives (HDDs). Some of the key challenges include:
- Cost per gigabyte – Flash remains significantly more expensive than HDDs in terms of cost per gigabyte of storage. HDDs can offer around 5-10 cents per gigabyte, while flash is typically 50 cents to $1 per gigabyte depending on technology. This makes flash prohibitive for high-capacity bulk storage use cases.
- Reliability and endurance – Individual flash memory cells have a limited lifespan and can only withstand a certain number of write/erase cycles before wearing out. Typically flash cells are rated for anywhere from a few hundred to a few thousand cycles. This wear-out effect requires the use of advanced flash controllers to manage endurance through wear leveling and error correction techniques.
- Scaling challenges – As process geometry shrinks below 20nm, flash memory faces technical hurdles around program/erase reliability and cell-to-cell interference. New materials and technologies like 3D V-NAND stacking are required to continue increasing density at smaller process nodes. There are questions around how long flash can continue scaling.
- Density – While the density of flash has increased steadily, HDDs have continued to advance rapidly in aerial density due to technologies like shingled magnetic recording and heat/microwave-assisted magnetic recording. HDDs remain far ahead in terms of maximum capacity available, with drives over 20TB now available compared to maximum SSD capacities below 100TB.
In summary, limitations around cost, reliability, scaling and maximum density pose challenges for flash adoption in some use cases.
