2. Semiconductors in everyday life

How semiconductors are used in everyday life? Since semiconductor itself is not sold in stores as electrical appliances, it may to be hard to understand, but in fact it is used in many electric appliances.
For example, temperature sensors used in air conditioners are made with semiconductors. Rice cookers cook rice perfectly because semiconductors control the temperature precisely. CPUs that operate personal computers are also made with semiconductors. Many digital consumer products in everyday life such as mobile phones / smartphones, digital cameras, televisions, washing machines, refrigerators and LED bulbs also use semiconductors.
In addition to consumer electronics, semiconductors play a central role in the operation of bank ATMs, trains, the internet, communications and other parts of social infrastructure, such as the medical network used for the care of elderly, among other things. Furthermore, efficient logistics systems help save energy and promote the preservation of the global environment. The number of car-mounted semiconductor devices has been increasing steadily. There are many types of car-mounted semiconductors. Particularly for future ADAS (Advanced Driver Assistance Systems), more semiconductors are expected to be used.
In this way, semiconductors help us to live comfortable lives.
