Process materials (gases and chemicals)
Which correctly describes a risk related to the supply of semiconductor materials?
- AThere is no risk, because semiconductor materials are easy to obtain anywhere
- BSemiconductors can be made without materials
- CSome high-purity materials and gases have limited suppliers, so supply may be disrupted by disasters or geopolitical circumstances
Show answer and explanation
Answer: C. Some high-purity materials and gases have limited suppliers, so supply may be disrupted by disasters or geopolitical circumstances
Some high-purity gases, chemicals, wafers and resists can be supplied by only a few companies or regions. Disruptions due to disasters, export controls or conflicts would greatly affect semiconductor production, so diversifying suppliers and holding inventory are important countermeasures.
