Tower Semiconductor company started out as a manufacturing plant for National Semiconductor in Migdal Haemek, Israel. The plant was established by the initiative of Israel engineer Dr. Giora Yaron, who began working as a physicist at the head office of National Semiconductor in Santa Clara, California in 1979, and persuaded the management to invest in Israel. Initially establishing a research and development center in Herzliya and in 1984 laid the cornerstone for the production plant. Mayor of Migdal Haemek Shaul Amor, was able to change the status of the city to a development zone area, to allow National Semiconductor to win this maximum state benefits provided by the investment encouragement law. Construction of the plant was completed in 1989. One of the first products that were manufactured by the company was an EPROM memory chip, which was developed by theFlash memory innovator Boaz Eitan at start-up company WaferScale Integration at the time.
