The microchip is one of the most important inventions and innovations of modern times. Almost all modern technology uses microchip technology, but most people do not know much about this powerful little item. To better understand the importance of microchip technology, it is important to know a bit more about the item itself.
What Is A Microchip?
A microchip is a device, often as small as a fingernail, which contains computer circuitry known as an integrated circuit. Microchips are generally manufacturer using semiconducting materials such as germanium and silicon. The microchip will generally be used as the logical brain of a device and for computer memory or RAM.
A microchip will have a set of interconnected electronic components including capacitors, resistors and transistors. These components will either be imprinted or etched into a small, extremely thin chip. The size of the chip will vary depending on the intended use.
The integrated circuit of the microchip is used as a control switch to perform certain tasks within a device. The capacitors in the circuit control the release of electricity and will generally be linked to a diode which stops the flow of electricity. The resistor considers the electrical current when it moves between the transistors, which are the components which function as the on and off switches.
How Microchips Are Made
To build a microchip, a wafer of semiconductor material will be needed. The microchip will then be build layer by layer onto the wafer. The process of building these layers is known as photolithography and will use a combination of light, chemicals and gas.
When making a microchip, a layer of silicon dioxide will be placed on the surface of the semiconductor material. This will then be covered by a photoresist. This is a material which is light-sensitive and will form the patterned coating on the surface of the chip with ultraviolet light. When the light shines on the material, it will harden in the exposed areas.
Gas will then be used to etch into the soft areas of the chip. This is a process that will be repeated and modified in order to build the component circuitry. To create the conducting paths for the chip, a thin layer of metal will be placed on the chip. The most common metal used is aluminum. Etching and photolithography are then used to remove the excess metal and only leave the pathways.
The Uses Of Microchips
Microchips are found in almost every modern device from computers to identification cards. Smartphone, computers and tablets are the most commonly used devices to have microchips in them. These microchips will enable users to connect to the internet and video call.
Microchips are everywhere in the modern world, but most people do not even think about them. These small devices power various functions in commonly used items such as smartphones and GPS devices. It is important that you know a bit about the microchip so that you can truly understand how important it is to daily life. Checkout Xilinx parts for sale online and grab the best deals now!
