Moore’s Law states that, every eighteen months, the number of components that can exist on an integrated circuit doubles. At a certain point, we have to worry about transistors no longer being able to block electrons, which leads to many false positives. There’s also the question of how small we want the transistors to be on a practical level. Currently, much research is focusing on bismuth (BI), a semi-metal. It’s important to note that silicon is just one of many substances that can be used to create transistors, and it wasn’t chosen for its size it was chosen because it’s the second most common element on the periodic table of elements.Įven to get something as small as the 1nm transistor, it’s advantageous to choose a different element. Suffice it to say, it would be impossible to create a silicon transistor smaller than that. What Problems Have to Be Solved to Miniaturize Transistors? The Atomic Size of Common Semiconductor Materials Most devices at this point are sub-100 nanometers. They’re currently roughly 7-10 nanometers in size, and they’re on track to shrink even further to 5 nanometers. Smartphones lead the way when it comes to consumer products. If you’re trying to determine the transistor size that will be the best for you, it’s useful to understand what the current industry standards are. They can give you personalized recommendations based on your situation. If you’re unsure which chip is best for your needs, we recommend speaking with a wafer manufacturer.
