Latest Patents
One of Case's latest patents is the "Mobius strip belt for linear CMP tools." This innovative tool is designed for the linear polishing of substrates and features an endless belt constructed as a Mobius strip. The design includes a 180-degree twist along its length, which effectively doubles the time interval between necessary belt changes due to wear-and-tear. This advancement significantly reduces costs associated with polishing by minimizing downtime. The belt is made from a rubberized, urethane composition, providing the necessary flexibility and strength to withstand the pressure applied during the polishing process.
Another significant patent by Case is the "Process for fabricating integrated circuits having shallow junctions." This process allows for direct contact to shallow junctions in integrated circuits, utilizing a specific aluminum CVD process. By depositing aluminum with a triisobutyl aluminum precursor onto a substrate with a nucleation layer, such as titanium nitride, Case's method ensures suitable contact while avoiding void defects that can occur without such a layer.
