Title: Yi-Jen Tsai: Innovator in Semiconductor Technology
Introduction
Yi-Jen Tsai is a prominent inventor based in Taipei, Taiwan. He has made significant contributions to the field of semiconductor technology, holding 2 patents that showcase his innovative approaches to device fabrication.
Latest Patents
One of Yi-Jen Tsai's latest patents is a method of planarizing semiconductor devices. This method involves forming a first region and a second region on a semiconductor substrate, where the first region has a larger thickness than the second. An interlayer dielectric layer is conformally deposited on both regions, followed by the formation of a photoresist on the second region. A bottom anti-reflective coating layer is then applied, and a planarization process is performed to remove portions of the interlayer dielectric layer, photoresist, and BARC layer.
Another notable patent focuses on sidewall protection of memory cells. This memory device includes a bottom electrode, a resistance switching element, a top electrode, a spacer, and a conductive feature. The resistance switching element is positioned over the bottom electrode, while the top electrode is situated above the resistance switching element. The spacer abuts the resistance switching element, and the conductive feature is placed over the top electrode, with the spacer partially located between the conductive feature and the top electrode.
