Latest Patents

Liu Yaocheng holds a patent for a CMOS structure that includes differential channel stressing layer compositions. This patent describes a CMOS structure comprising an n-FET device and a p-FET device. The n-FET channel region features a first silicon material layer situated upon a silicon-germanium alloy material layer. Meanwhile, the p-FET channel includes a second silicon material layer located upon a silicon-germanium-carbon alloy material layer. The design of these layers is crucial, as the silicon-germanium alloy material layer induces a desirable tensile strain within the n-FET channel, while the silicon-germanium-carbon alloy material layer suppresses undesirable tensile strain within the p-FET channel region. This innovative approach to CMOS technology is a testament to Liu's expertise and creativity in the field.
