27. Difficulties in Manufacturing Microchips

1. According to the essay, what is the primary reason microchip factories must be extremely clean?
1. To protect the health of the engineers and scientists.
2. Because the machines used are very sensitive to temperature.
3. Because even a tiny particle of dust can destroy a microchip.
4. To keep the expensive chemicals from becoming contaminated.
The essay states that only a few companies and countries can make the most advanced chips. What is the main reason given for this?
1. The high cost of building the factories and buying the machines.
2. shortage of skilled engineers and scientists worldwide.
3. The limited supply of silicon needed for the chips.
4. The long time it takes to train people for the manufacturing process.
Based on the information in the essay, which of the following is NOT listed as a major difficulty in manufacturing microchips?
1. The need for constant improvement due to fast-changing technology.
2. The difficulty of sourcing the necessary raw materials.
3. The extremely small size of the circuits on the chip.
4. The lengthy and complex multi-step production process.
The author compares the size of the microchip's circuits to a human hair to show that they are:
1. fragile and flexible.
2. much thinner.
3. made of similar materials.
4. essential for modern devices.
What is the overall purpose of the essay?
1. To explain why microchips are becoming more expensive for consumers.
2. To describe the steps involved in the microchip manufacturing process.
3. To argue that more countries should invest in microchip production.
4. To outline the key challenges faced when manufacturing microchips.
