We take electronics for granted in todays society. Microchips are in everything! Computers, TVs, Smart Phones, Microwaves even your car! If it plugs in and turns on there’s a good chance a microchip will be inside.
Have you ever wondered what is a microchip? I don’t want to cover the history of chips or integrated circuits (IC) in this article, however lets leave it as miniaturized electronic components on a die that is encased in a plastic shell. The components are usually transistors and millions of them can be on a die to compose a single chip.
These are older microchips and the there are a few where you can actually see the die through a small window. These chips were know as EPROMs and were programmable!
Actual Microchip Die!
This is the inside Die Chips found in sophisticated IC’s. The die was fully processed and the next step was to bond gold wires to the different connection points on the IC die and connect them to pins on a plastic IC package. This step was not done.
These are fascinating to study under a strong magnifying glass or microscope. Great for making “electronic jewelry”, study and training.
Have you ever wondered what your life would be like if we never invented the micro chip? Micro chips and to that extent the micro processor should be hailed as one of the greatest inventions of all time. Most of our modern life would not be possible if we were not able to fit billions of transistors in the space of a postage stamp silicon wafer. Just think about that statement for a moment! Your mobile phone would be the size of a car, your home computer the size of a room in your house. Constantly swapping out burnt vacuum tubes.
Micro chips to the rescue.
A Silicon Wafer Is Born:
Ever wondered how these chips are made? I never gave it a thought myself until I stumbled across these Silicon Wafers. For some reason or another these wafers were deemed defective so they were unable to continue the journey into computers, phones and other electronics. Some of the wafers were destined to become DRAM’s (memory) some designed to be micro processors, while others custom circuits for a specific job.
