Latest Patents

Among his latest patents is a semiconductor interconnect structure. This invention provides an interconnect structure for a semiconductor device, which includes a first metal layer containing a first metal line. The structure also features a dielectric layer located over the first metal layer, which contains a first sub-via electrically coupled to the first metal line and a second sub-via that is different from the first. Additionally, there is a second metal layer located over the dielectric layer, which contains a second metal line electrically coupled to the second sub-via. Notably, no other metal layer is situated between the first and second metal layers.

Another significant patent is a method for integrated circuit mask patterning. This method transforms an integrated circuit (IC) pattern into one or more patterns suitable for subsequent processing, such as mask fabrication. It involves receiving an IC pattern with an arbitrary shape and using a computer to derive an approximation IC pattern that is user-defined and fabrication-friendly. The method includes calculating a pattern approximation error and checking if it meets a user-defined threshold. If it does, the IC pattern is replaced with the approximation for further fabrication.
