Latest Patents
One of his latest patents is titled "Method for Asymmetric Spacer Formation." This method integrates into the manufacturing process for semiconductor devices, allowing for the formation of asymmetric spacers that improve device performance. The process involves creating a gate structure over a substrate and forming a sidewall layer that includes a first portion overlying the gate structure. A photoresist structure is then formed adjacent to this first portion and subjected to an ion beam, which shields part of the first portion from radiation damage. This innovative approach enables faster etching rates for unshielded sidewall portions, enhancing the overall manufacturing efficiency.
Another significant patent is "Apparatus to Evaluate Hot Carrier Injection Performance Degradation and Method Therefor." This invention provides a method and apparatus for assessing the performance degradation of semiconductor devices due to hot carrier injection (HCI). The device under test (DUT) undergoes a series of stress cycles, with conditions such as overvoltage applied to evaluate its performance. By characterizing physical parameters like case temperature during benchmark cycles, this method allows for the extrapolation of data to predict the expected lifetime of the DUT under nominal operating conditions.
