Silicon Origins: The journey begins with silica sand, an abundant material found on our planet. This sand undergoes a series of transformations. First, it is heated and spun, creating a molten mixture. Then, a small seed crystal is carefully dipped into this hot concoction. As if by magic, a large single-crystal silicon ingot emerges. This ingot serves as the raw material for microchip production1.
Wafer Formation: The next step involves slicing the silicon ingot into ultra-thin wafers. These wafers act as the canvas for microelectronic devices. Each wafer is meticulously polished to perfection, ensuring a smooth surface for what’s to come2.
Pattern Creation: Engineers design intricate patterns for the microchips. A photosensitive chemical is applied to the wafer, and UV light shines through a stencil, creating the desired layout. Since wafers are large, this photolithography process is repeated multiple times2.
Ion Bombardment: To alter the physical and electrical properties of the patterns, charged atoms or ions bombard the exposed areas on the silicon. This step fine-tunes the microchip’s functionality2
