Abstract
A conductor-filter system, a conductor-insulator system, and a charge-injection system are provided. The conductor-filter system provides band-pass filtering function, charge-filtering function, voltage-divider function, and mass-filtering function to charge-carriers flows. The conductor-insulator system provides Image-Force barrier lowering effect to collect charge-carriers. The charge-injection system includes the conductor-filter system and the conductor-insulator system, wherein the filter of the conductor-filter system contacts the conductor of the conductor-insulator system. Method and apparatus on charges filtering, injection, and collection are provided for semiconductor device and nonvolatile memory device. Additionally, method and apparatus on charges injection using piezo-ballistic-charges injection mechanism are provided to the charge-injection system and devices operation. Memory cells and array architectures and manufacturing method thereof are provided.
