IQE sues Tower Semi over porous silicon

Welsh wafer maker IQE has filed a lawsuit against foundry Tower Semiconductor in Israel.

IQE, based in Cardiff, claims there is evidence suggesting misappropriation of IQE’s trade secrets relating to its “porous silicon” technology. The porous silicon could underpin device used in 5G cellular communications and to make sensors.

Tower is in the process of being acquired by Intel in a deal worth $5.4bn.

IQE filed its complaint in US federal court in California (case number 8:22-cv-00867) under federal and California state law in relation to the misappropriation of trade secrets, correction of inventorship, breach of contract, unfair competition, and intentional interference with prospective economic advantage.

“We brought about these claims as we have significant reason to believe that Tower has misappropriated IQE’s proprietary trade secrets for its own benefit,” said Tom Dale, general counsel at IQE. “Our technology, processes and intellectual property are vital in underpinning IQE’s products and solutions and in maintaining our market-leading position in advanced semiconductor materials. We will vigorously protect them and will provide further updates as material developments occur.”
