1. What is IC Chips?
IC chips are sets of electronic circuits on a small flat silicon semiconductor material or a chip.
It is a semiconductor wafer with millions of tiny capacitors, transistors, and resistors.
Integration of a higher number of minute MOS transistors into smaller chips results in faster and less expensive devices.
2. What do IC Chips do?
You can use IC chips for different functions depending on the applications such as:
- Timer as it is in integral device in digital watches
- Computer memory being an integral device in the RAM and ROM drives.
3. What is Inside IC Chips?
IC chips consist of millions of different components that assist in the normal function of the IC chip.
The main components of the IC chips include:
- Resistors that control the flow of current to other components on the device.
- Capacitors which are used in the storage of electrostatic energy in electric fields.
- Transistors which you can use in switching or amplifying electrical power and electronic signals.
- Semiconductor wafers such as silicon
- Copper which acts as the main electric conductor
4. How are IC Chips made?
In order to make an IC chip, you need to follow the following steps:
Step One: Preparation Stage
At this point you need to have the blue print of the IC chip that you intend to make ready.
You need to come up with a proper design which can either be standard or it can also be unique.
Standard designs are available for you to choose from different shelves such as amplifiers, and analog switches among others.
Unique designs will require research, development and extensive design work such coming up with new microprocessors for computers.
With the design at hand, you will need to find the raw materials for making the integrated circuit chips.
The main raw materials that you will need include:
- Pure silicon as the basis of most IC chips
- Aluminum which acts as the connector between different IC chip components.
- Mounting package which can either be plastic or ceramic among other materials.
You have to ensure that you are working in a clean room with filtered air, light frequencies and no foreign particles.
The operators within the clean room should also have gloves, lint-free garments, and covers for their feet and head.
Step Two: Actual Manufacturing Process
First you will make a single yet thin slice of silicon consisting of hundreds of integrated circuits.
After that you will cut the individual IC circuits apart thus making individual IC chips.
The manufacturing process begins with:
i. Preparation of Silicon Wafer
You will heat the silicon to melting point of about 1400 degrees Celsius inside a vacuum chamber.
Make sure that you avoid contamination by containing the heated region by surface tension which gets rid of impurities.
The impurities flow down to the base of the silicon which you will cut off completely and remain with pure silicon.
Using a wafer slicer, you will cut a thin round silicon wafer according to size specifications before polishing the surface.
Coat the layer of silicon wafer using silicon dioxide resulting in the formation of insulating base and prevent further oxidation.
Using a computer aided drafting machine, you will prepare the design and then make the image into a mask.
After that you will optically reduce the mask and transfer it to the surface of the wafer.
The mask has cleat and opaque parts depending on the design with integrated images of all the components.
You will place a drop of photoresist material at the center of silicon wafer and spread it by spinning rapidly.
Bake the photoresist after spreading to remove the solvent before irradiating using short wave ultraviolet light.
Remove the mask and dissolve portions of the photoresist before chemically etching the areas that are still uncovered.
You can as well subject it to chemical doping in an attempt to create layers of P and N regions.
You will then dope the device by either atomic diffusion or Ion implantation.
Doping involves the addition of a layer that will create P or N regions.
Atomic diffusion involves placing wafers in a quartz tube oven and heating to about 816 – 1205 degrees Celsius.
You will add the doping chemical on an inert gas which will deposit on the hot surface of the wafers without masks.
Ion implantation involves ionizing dopant gas to provide high energy dopant ions and then fired to specific regions.
The ions will go through the wafer and remain implanted.
Step Three: Making of Successive Layers
In this stage, you will repeat all the process in step two for every successive layer of the chips.
You might need to lay down a layer of silicon dioxide that will provide an insulator between the components.
You can achieve this through the process of chemical layer deposition before placing a final layer of silicon dioxide.
You will also perform final etching that will open up the contact points before depositing a layer of aluminum.
The layer of aluminum will make the contact pads after which you will test the individual layers for electrical functionality.
Step Four: Making Individual IC chips
In this case, you will separate the hundreds of individual chips by scoring cross hatches of line using fine diamond cutters.
After that, you will place the sheets under pressure and they will separate thus forming individual IC chips.
You will inspect the individual chips to remove any damaged chips as well as chips that fails the electrical test.
The good chips are bonded individually into mounting packages before connecting the thin wire leads by thermocompression or ultrasonic bonding.
You will then mark the chips using identity marks such as part numbers as well as other information.
Step Five: Final Packaging
After the final testing you will package the IC chips in a hard plastic package.
This is the part that you will see when you look at the motherboard of a computer or any device with IC chips.
The package has connection pins that connect the IC chips to the printed circuit board.
After that, the integrated circuit chip will be ready for shipping.

- Drag soldering
In this guide, we will focus on drag soldering as the main process of mounting IC chips.
Step One: Preparation Stage
At this stage you will collect all the materials that you need such as solders, soldering station, flux, and clean wipes.
You will also clean all the equipment as the process does not require any form of contamination.
Step Two: Mounting Process
First, you will apply fresh amounts of fresh flux and then place the IC chip carefully on the board.
You should make sure that the pins line up as proper as they can be.
After that you can either tack a few pins or use high temperature adhesives to hold the IC chip in place.
Step Three: Soldering Process
You can start by tinning the tip after cleaning and filling the bevel with some solder.
The solder will glide over the pins, heating them, and depositing the right amount at the end of every pin.
The right amount of solder will deposit at the end of every pin due to the flux, temperature difference and surface tension.
It results in high quality fillets that require no solder wick as the right amount of solder deposits at every transition.
You have to be careful not to put too much solder that will overload the pocket.
Glide the pins gently with minimal pressure to allow the pins to mount properly on the board.
After that, you need to clean the area with clean water or alcohol to get rid of any impurities left.
