Study Notes
Microchip Structure
- A microchip is a set of electronic circuits on a small flat piece of silicon.
- Transistors on the chip act as miniature electrical switches that can turn a current on or off.
Silicon in Microchips
- Silicon is the material of choice in the chip industry due to its semiconductor properties.
- Silicon can be found everywhere, made from sand, and is the second most abundant element on earth after oxygen.
- Silicon wafers are made using silica sand, melted and cast into a large cylinder called an ingot, then sliced into thin wafers.
Microchip Features
- A microchip can contain billions of transistors, requiring extremely small features.
- Chip features are measured in nanometers, with the most advanced microchips containing features just a few dozen nanometers in size.
- Extreme Ultraviolet Technology enables the reduction of feature sizes even further.
Categorization of Microchips
- Microchips can be categorized by functionality and type of integrated circuitry.
- In terms of circuitry, a chip can be analog, digital, or mixed signal.
- Analog chips process continuous signals, while digital chips process binary signals.
Types of Microchips
- There are four main categories of microchips: Logic chips, Memory chips, application-specific integrated chips (ASICs), and system-on-a-chip devices (SoCs).
- Logic chips, such as CPUs and GPUs, process information to complete tasks.
- Memory chips, including volatile and non-volatile types, store information.
- ASICs are simple single-purpose chips used for repetitive processing tasks.
- SoCs are integrator chips that combine multiple chips and circuits in a single chip.
This quiz covers the basics of microchips, also known as computer chips or integrated circuits, including their structure, function, and materials used.
