Title: Innovations of Li-Yen Liang in Semiconductor Technology
Introduction
Li-Yen Liang is a prominent inventor based in Kaohsiung, Taiwan. He has made significant contributions to the field of semiconductor technology, holding three patents that showcase his innovative approach to device design and manufacturing.
Latest Patents
Li-Yen Liang's latest patents include a circuit structure, a semiconductor device, and a method of manufacturing the same. This semiconductor device is applicable in a three-dimensional AND flash memory device. It features a dielectric substrate that consists of a first region and a second region. The composite stack structure is positioned over the dielectric substrate in both regions. Additionally, a vertical pillar array is integrated within the composite stack structure in the first region, while a resistor is laterally adjacent to the vertical pillar array, extending below, through, and above the composite stack structure.
Another notable patent is for a 3D AND flash memory device, which comprises a gate stack structure, a channel pillar, first and second conductive pillars, a charge storage structure, and a protective cap. The gate stack structure is situated on a dielectric substrate and includes alternating gate layers and insulating layers. The channel pillar penetrates through the gate stack structure, while the first and second conductive pillars are located within the channel pillar and also penetrate through the gate stack structure. The charge storage structure is positioned between the gate layers and the sidewall of the channel pillar, and the protective cap covers the top surface of the channel pillar, isolating the conductive pillars from the top gate layer.
