Samsung patents special glass mix for faster computer memory

Patent drawing from the official filing.

Samsung has secured a patent for a specific chemical recipe for a dielectric material, which is a substance that helps store electrical charge in memory chips. The formula combines barium titanate with small amounts of rare earth metals like thulium or lutetium to create a stable solid solution.

Why it mattersThis type of material science work is essential for making memory chips that hold data reliably, though it is a very technical step in chip manufacturing.

In the filing’s own words

The preset invention relates to dielectric material, and device, and memory device comprising the same. According to an aspect, provided is a dielectric material having a composition represented by Formula 1: <Formula 1> (100-x-y)BaTiO 3.xBiREO 3.yABO 3. wherein, in Formula 1, RE is a rare earth metal, A is an alkali metal, B is a pentavalent transition metal, and 0<x<50, 0<y<50, and 0<x+y<50 are satisfied.

What exactly they claim (claim 1)

1. A dielectric material having a composition represented by Formula 1: (100- x - y)BaTiO 3.x BiREO 3.y ABO 3 <Formula 1> wherein, in Formula 1, RE is at least one of thulium (Tm) or lutetium (Lu), A is an alkali metal, B is a pentavalent transition metal, and 0<x≤20, 0<y≤10, and 0<x+y≤30, wherein the dielectric material is a solid solution.
