    • The present invention provides a SONOS type nonvolatile or flash memory device and related programming/erasing methods. The device has a deep well region of a first conductive type that isolates a well region of a second conductive type from a substrate to enhance programming and erasing operation characteristics. In the erasing method, first electrons are erased by one of Hot Hole Injection (e.g., gate-to-drain Hot Hole Injection) or tunneling in a first step, and second electrons that are not erased in the first step are erased by the other of tunneling (e.g., gate-to-body tunneling) or HHI in a second step. Preferably, a time gap intervenes between the first and second steps.

    • An STI structure and fabricating method thereof are disclosed. The STI fabricating method comprises forming a pad oxide layer and a first nitride layer on a substrate. A trench is formed by etching the first nitride layer, the pad oxide layer and the substrate. An oxide and a second nitride layer are deposited on the surface of the substrate including the trench. A spacer is formed on the lateral walls of the trench by etching the second nitride layer. A buried oxide is grown in the substrate underneath the trench by performing thermal oxidation on the substrate. The trench is then filled by depositing an insulating layer after removing the spacer and performing a planarization process. The STI fabricating method can reduce substantially a total parasitic capacitance. Therefore, gate RC delay is reduced and the operating speed of a transistor increases. In addition, the STI fabricating method can substantially reduce junction leakage because the junction between the bottom of the source/drain and N-well or P-well is not formed. The STI fabricating method can improve isolation characteristics of P-well and N-well, and increase a circuit design margin due to the improvement of latch-up characteristic.
    • 公开了STI结构及其制造方法。 STI制造方法包括在衬底上形成焊盘氧化物层和第一氮化物层。 通过蚀刻第一氮化物层,衬垫氧化物层和衬底形成沟槽。 在包括沟槽的衬底的表面上沉积氧化物和第二氮化物层。 通过蚀刻第二氮化物层,在沟槽的侧壁上形成间隔物。 通过在衬底上进行热氧化,在沟槽下方的衬底中生长掩埋氧化物。 然后通过在去除间隔物并进行平坦化处理之后沉积绝缘层来填充沟槽。 STI制造方法可以实质上减少总的寄生电容。 因此,栅极RC延迟减小,晶体管的工作速度增加。 另外,由于不形成源极/漏极的底部与N阱或P阱之间的结,因此STI制造方法可以显着地减少结漏电。 STI制造方法可以改善P阱和N阱的隔离特性,并且由于闩锁特性的改善而增加了电路设计裕度。

    • Non-volatile memory elements having a high programming speed and a reduced constant voltage requirement for data storage are disclosed. Each memory cell of a disclosed example non-volatile SRAM includes an SRAM unit and a non-volatile memory unit. When power is off, the data levels of data nodes of the SRAM unit are programmed into a corresponding non-volatile memory element through a pass transistor connected to the data node. When the power is on, the data levels programmed into the non-volatile memory elements are recalled to the corresponding data nodes through the pass transistors, and then the programmed non-volatile memory element is erased. The non-volatile memory element has an oxide stack including a tunnel oxide film, a storage oxide film, and a blocking oxide film. A potential well where the SRAM unit is formed is isolated from a potential well where the non-volatile memory unit is formed. Bias voltages are applied during program, recall and erase modes to the potential well where the non-volatile memory unit is formed.
