Labels:text OCR: ELECTRONIC COMPONENTS TRANSISTOR INSULATING SILICON DIOXIDE LAYER CONDUCTIVE SEMICONDUCTING ALUMINUM SILICON LAYERS LAYER Manufacturing a silicon chip is a complex process involving the layering of conducting, semiconducting, and insulating materials. These layers are selectively etched away, leaving a microscopic pattern of silicon and aluminum. This pattern forms millions of electronic components, such as diodes, capacitors, and transistors, like the one shown above.
