Title: Innovations of Chuan H Liu

Introduction

Chuan H Liu is a notable inventor based in Taipei, Taiwan. He has made significant contributions to the field of semiconductor technology, holding a total of 5 patents. His work primarily focuses on methods that enhance the reliability and performance of dielectric thin films and oxide layers in electronic devices.

Latest Patents

One of his latest patents is a method for fabricating an oxide layer on silicon with carbon ions introduced at the silicon/oxide interface. This innovative fabrication method aims to reduce hot carrier effects, which is crucial for the performance of flash memory devices. The process involves conducting a first inert ambient annealing, followed by the growth of an oxide layer on the silicon substrate. A second inert ambient annealing is then performed on the oxide layer, after which carbon ions are incorporated into the interface between the oxide layer and the silicon substrate. Finally, a third ambient annealing process is conducted to complete the fabrication.

Another significant patent by Liu is a reliability testing method for dielectric thin films. This method employs an exponential current ramp test with a delay time to assess the reliability of the dielectric thin film. The results yield an exponential current ramp charge-to-breakdown distribution, represented by cumulative distribution failure percentages. This method allows for the calculation of various constants related to current stress and charge-to-breakdown, ultimately determining the reliability of the dielectric thin film.
