Tower Semiconductor

Tower Semiconductor (TSEM), an Israeli contract chipmaker that builds other companies' designs, specialising not in the smallest transistors but in analog and mixed-signal work: radio-frequency, power management, image sensors and silicon photonics. Founded in Migdal Haemek in 1993, it agreed to be bought by Intel in 2022, and the deal collapsed in 2023 when Chinese regulators did not clear it. TSEM on Robinhood Chain is a Robinhood Stock Token, a tokenised debt security issued by Robinhood Assets (Jersey) Limited and backed by Tower Semiconductor shares held in custody at Alpaca Securities.
