    摘要: Semiconductor devices including a plurality of gate structures disposed on a semiconductor substrate are provided. Each of the gate structures includes a tunnel dielectric layer, a floating gate, an inter-gate dielectric layer, a control gate, and a mask layer. Liners cover opposing sidewalls of adjacent floating gates. Spacers are disposed on the liners, the spacers protruding from opposing sidewalls of adjacent ones of the gate structures, and a top of each of the spacers is disposed below a top of a corresponding one of the gate structures. The liners define sidewalls of respective air gaps and the spacers define tops of the respective air gaps.

    摘要: A method of forming a semiconductor device, where the method may include forming a first trench in a semiconductor substrate, forming first device isolation patterns that fill the first trench, forming spacers on sidewalls of the first device isolation patterns, forming a second trench in the semiconductor substrate between first device isolation patterns, and forming second device isolation patterns that fill the second trench. The second trench is formed using an etching process adopting the first device isolation pattern and the spacer as a mask.

    摘要: A non-volatile memory device including a barrier spacer that serves to protect a control gate, including a metal layer, from damage that may result from exposure to a cleaning solution and/or oxygen. With the barrier spacer layer, a cleaning process using a high-power cleaning solution may be used to effectively remove etch byproducts. An oxidation process may be performed to cure etch damage of an intergate dielectric pattern, a floating gate and a gate insulator. The barrier spacer and/or the oxidation process enable a non-volatile memory device having enhanced speed and reliability to be formed.

    摘要: Non-volatile memory devices and fabrication methods thereof are provided. The device includes a plurality of isolation layers formed at a semiconductor device, a plurality of stacked gates crossing over an active region between the isolation layers, and an oxidation barrier layer covering the stacked gate. Each of the stacked gates has a control gate electrode crossing over the active region, a floating gate interposed between the control gate electrode and the active region, and an inter-gate dielectric layer interposed between the control gate electrode and the floating gate. Also, the inter-gate dielectric layer has a bottom dielectric layer, an intermediate dielectric layer and a top dielectric layer which are sequentially stacked. The oxidation barrier layer is formed prior to a subsequent thermal oxidation process for curing etch damage that occurs during formation of the stacked gates.

    摘要: Provided are a non-volatile flash memory device and a method of making the non-volatile flash memory device. A common source line is formed simultaneously with the formation of stacked transistors. The common source line is formed of the same material layer as floating gate pattern. The common source region and a scribe line region are simultaneously formed thorough the same photolithography process in a semiconductor substrate. Additionally, the common source line and butted contact are patterned simultaneously through the same photolithography process. Accordingly, the common source line process can be advantageously completed with very low cost and simplicity.
