Latest Patents

One of Kim's latest patents focuses on a TDDB test pattern and method for testing the dielectric of MOS capacitors. This innovative test pattern circuit is designed to reduce testing time while statistically improving measurement precision. The circuit includes multiple unit test patterns, each featuring a capacitor connected to a stress voltage. As the stress voltage is applied, the current flowing from the capacitor is measured over time. The dielectric in the capacitor experiences breakdown over time, leading to a sudden change in current. Traditional test pattern circuits require serial testing of each unit cell, resulting in significant measurement time when many unit cells are involved. Kim's circuit allows for simultaneous measurements across all unit cells, greatly reducing testing time, enhancing data collection, and improving statistical accuracy while also lowering costs.
