Samsung patents stacked oxide layers for semiconductor devices
Samsung has filed a patent for a semiconductor component that uses a specific stack of three different oxide materials. The design places layers of titanium oxide, aluminum oxide, and a third oxide material between two conductive layers to form the device structure.
In the filing’s own words
A semiconductor device including a first conductive layer; a first dielectric layer on the first conductive layer; a second conductive layer on the first dielectric layer; and a second dielectric layer formed between the first dielectric layer and the second conductive layer. The second dielectric layer includes a first layer including titanium oxide, a second layer including aluminum oxide, and a third layer including niobium oxide, vanadium oxide, or tantalum oxide, which are sequentially stacked on the first dielectric layer.
What exactly they claim (claim 1)
1. A semiconductor device comprising: a first conductive layer; a first dielectric layer on the first conductive layer; a second conductive layer on the first dielectric layer; and a second dielectric layer formed between the first dielectric layer and the second conductive layer, wherein the second dielectric layer includes a first layer including titanium oxide, a second layer including aluminum oxide, and a third layer including niobium oxide, vanadium oxide, or tantalum oxide, which are sequentially stacked on the first dielectric layer.
