But because it is already a mature field with a stable pace of research and development, and the technology can be bought, recruitment needs are limited. "But in electrical engineering, from the vacuum tubes of many years ago to the semiconductors of today, new devices with new applications are always being developed, and this has created ever greater demand.
就工學院的領域來說，「其實化工才是無所不在，但因為研發穩定，技術可以用買的，已經成為成熟領域，所以對人才的需求有限」，李嗣涔說，相對的，電機系早期研究真空管，現在是開發半導體，不斷有新功能湧現，才導致需求越來越大。
