True or False: Most semiconductors today are made from metal oxides.

The statement that "Most semiconductors today are made from metal oxides" is inaccurate. The primary materials used to fabricate most semiconductors, especially in the context of modern electronics, are silicon and gallium arsenide, rather than metal oxides. Silicon is the most widely used semiconductor material due to its well-established processing technology and excellent electrical properties.

While metal oxides can be used in some specific applications, such as in transparent conductive oxides (e.g., indium tin oxide) and certain types of thin-film transistors, this does not account for the majority of semiconductor devices. Therefore, the answer is better reflected as "False," because silicon and gallium arsenide remain the dominant materials in the semiconductor market.
