The transistor, a tiny device smaller than your fingernail, revolutionized electronics upon its invention in 1947. This semiconductor invention replaced bulky vacuum tubes, paving the way for smaller, more efficient, and powerful electronic devices. Today, transistors are the unsung heroes underpinning modern technology. billions of them working together form the heart of every smartphone, computer, and internet server. From the apps you use to the websites you browse, transistors control the flow of electricity, enabling the digital world we know. Despite their age, they continue to be refined and miniaturized, constantly pushing the boundaries of what’s possible in electronics.
