Microchips are tiny marvels of engineering, cramming billions of transistors onto a fingernail-sized piece of silicon. Making them involves a complex, super precise process done in special cleanroom facilities. Here's a simplified breakdown:
1. **Starting with Silicon:**
- Ultra-pure silicon, derived from sand, is grown into cylindrical ingots.
- These ingots are sliced into thin wafers, the base for the microchip.
2. **Layering and Patterning:**
- Different materials are deposited on the wafer in precise layers.
- A light-sensitive material called photoresist is applied.
- Using a special mask and light exposure, the desired circuit patterns are transferred onto the photoresist.
3. **Building the Circuits:**
- The photoresist is developed, etching away unwanted material to form the circuit features.
- This process is repeated to build up the intricate layers of transistors and connections.
4. **Finishing Touches:**
- The wafer is cleaned and inspected to ensure everything is perfect.
- Finally, the wafer is diced into individual microchips, ready for packaging and use.
This is a simplified view, the actual process involves hundreds of steps and takes months to complete.

Day 5
The semiconductor industry employs highly sophisticated and standardized processes for manufacturing chips, also known as integrated circuits (ICs), to achieve high performance, reliability, and yield.
This multi-step process involves precisely layering and patterning various materials on a silicon wafer to create the desired electronic circuits. Here's a breakdown of the key stages in standard chip manufacturing:
The process starts with a thin slice of single-crystal silicon, called a wafer. The silicon is meticulously cleaned and polished to provide a pristine foundation for the circuit layers. the wafer. Here's the general flow:
1. Wafer Preparation: Silicon wafers are cleaned and polished to remove contaminants and imperfections, ensuring a smooth and uniform surface.
2. Deposition: Thin films of materials, such as silicon dioxide (SiO2), silicon nitride (Si3N4), metals, and polysilicon, are deposited onto the wafer using techniques like chemical vapor deposition (CVD), physical vapor deposition (PVD), or atomic layer deposition (ALD).
3. Photolithography: Each layer's pattern is transferred onto the wafer using photolithography. This involves coating the wafer with a photoresist, exposing it to UV light through a mask, and then developing the pattern.
4. Etching: Unwanted material is selectively removed from the wafer using wet or dry etching techniques, defining the features of the integrated circuit.
5. Doping: Dopant atoms are introduced into the wafer to modify its electrical properties and create regions with specific conductivity types (n-type or p-type). This is typically done using ion implantation or diffusion processes.
6. Annealing: The wafer undergoes annealing processes to activate dopants, repair crystal defects, and relieve stress induced by fabrication processes.
Throughout the entire manufacturing process, strict quality control measures are implemented to ensure that the fabricated chips meet the required specifications and standards. Additionally, advanced process technologies and materials are continually being developed to enable higher performance, smaller feature sizes, and increased functionality in semiconductor devices.

Today, I focused on learning the industry standard for making chips.
In my research, I stumbled upon this video, and these are the steps involved in the making of ICs that were mentioned:
a) Gathering of semiconductor materials
This involves gathering materials that have a high concentration of silicon, e.g., sand.
b) Next, the sand is melted in a crucible to separate the silicon from the sand because the sand contains silicon, carbon, and oxygen.
c) Then, further processing is done to generate ultra-pure silicon.
d) Thereafter, a seed crystal is placed in contact with molten silicon and then slowly pulled away.
e) This results in silicon atoms being deposited on the bottom surface, which forms a large cylindrical boule or a single crystal ingot of pure silicon.
f) The boule is then sliced into thin wafers (usually 1–12 inches in diameter).
g) Thereafter, the production of the chip begins.
h) Firstly, a thin, non-conducting layer of silicon dioxide is grown or deposited on the wafer surface. This process is called deposition.
I) Then, the silicon wafer is coated with photosensitive and light resistant materials to prepare it for lithography.
j) Next, the prepared silicon wafers are placed in a lithography machine and exposed to UV light, which results in the exposed area getting hardened while the unexposed areas are etched away by hot gases.
k) Then, the electrical conductivity of different parts of the chip is altered by doping them with chemicals under heat and pressure.
l) Next, a thin layer of metal (usually aluminum) is overlaid onto the chip to create the conducting parts between the components, and the etching process is used to remove the unneeded aluminum and leave the conducting pathways.
m) Lastly, each chip is tested for performance before it is separated from other chips on the wafer with a saw.
This video was very informative. It explained in detail what chips are, the materials they are made from, and how they are made in the industry. It also contained pictorial representations of the various steps and materials.
I really enjoyed it. If you are interested in watching the video, this is the link.

Understanding How Your Computer Works
Have you ever thought about how your computer works? More precisely, what is your computer's processor made of, or how is it created?
The processor, often called the computer's "brain", is a marvel of modern engineering. It performs millions of calculations per second, enabling everything from browsing the internet to running complex applications. But what exactly goes into making this crucial component?
The Journey of Processor Creation:
- Design Phase: It all starts with a design. Engineers use specialized software to create intricate blueprints for the processor. This design phase can take years and involves extensive research and development.
- Raw Materials: The primary material used in processors is silicon, which is derived from sand. This silicon is purified and shaped into wafers.
- Fabrication: The silicon wafers undergo a process called photolithography, where they are exposed to light through a mask, creating intricate patterns that define the processor's circuits. This process is repeated multiple times to build up the layers of the processor.
- Assembly and Testing: Once the wafers are complete, they are cut into individual chips and tested rigorously to ensure they meet performance standards. Only the best chips pass these tests and move on to the final assembly stage.
- Packaging: The final step involves packaging the chip in a protective case, which is then integrated into the computer's motherboard.
Next time you use your computer, take a moment to think about the journey of its processor, from raw silicon to a powerful computing device.
Look at this amazing video below, where you can learn a bit more about the creation process of a computer processor.

Day 5,
we dive into the standard way of making IC chips.
Chips are the backbone of our modern technology, powering everything from smartphones to cars. Here are some standard way of making a chip.
Silicon Wafer Production:
The journey begins with silicon, a special material that serves as the foundation for chips. Silicon is derived from sand and undergoes a purification process to achieve high purity.
The purified silicon is then sliced into thin, circular discs called wafers. These wafers act as the starting point for chip fabrication.
Photolithography:
Engineers create a blueprint for the chip using a process called photolithography. Think of it as designing a detailed map that outlines how the chip’s components will be arranged and connected.
The smaller and more intricate the blueprint, the more powerful the resulting chip can be.
Transistor Fabrication:
Next, tiny components called transistors are built on the wafer. Transistors are the fundamental building blocks of chips.
This step involves selectively removing material and adding new substances to create the transistors.
Metallization:
To connect the transistors, a thin layer of metal is deposited on the wafer. This process is known as metallization.
The metal layer forms the intricate wiring that links different parts of the chip.
Wafer Dicing:
Once all components are in place, the wafer is cut into individual chips. Each chip contains a complete circuit.
These chips are then tested rigorously to ensure they function flawlessly.
Packaging:
The chips are encapsulated in protective casings through a process called packaging.
In summary, making computer chips invhttps://lnkd.in/ePr_yfat a clever interplay of science and engineering.
