    摘要: An apparatus for manufacturing a semiconductor includes a polyhedral transfer chamber, a first process module for forming a gate dielectric layer by ALD, and a second process module for thermally treating the gate dielectric layer. The first process module is in communication with a first side of the transfer chamber. The second process module in communication with a second side of the transfer chamber. The apparatus further includes at least one load-lock chamber in communication with a third side of the transfer chamber.

    摘要: In a method of manufacturing a floating gate of a non-volatile semiconductor memory, a pattern is formed on a substrate to have an opening that exposes a portion of the substrate. A first preliminary polysilicon layer is formed on the pattern and the exposed portion of the substrate to substantially fill the opening. A first polysilicon layer is formed by partially etching the first preliminary polysilicon layer until a first void formed in the first preliminary polysilicon layer is exposed. A second polysilicon layer is formed on the first polysilicon layer.

    摘要: Disclosed herein is a method of forming a floating gate in a non-volatile memory device having a self-aligned shallow trench isolation (SA-STI) structure. First, a tunnel oxide layer is formed on a semiconductor substrate having a SA-STI structure. Next, a first floating gate layer is formed on the tunnel oxide layer at a first temperature of no less than about 530° C. A second floating gate layer is then formed on the first floating gate layer at a second temperature of no more than 580° C. After depositing the first floating gate layer, the second floating gate layer is in-situ deposited to prevent the growth of a native oxide layer on the surface of the first floating gate layer. Thus, gate resistance can be reduced and process time can be shortened.

    摘要: In methods of forming an oxide layer and an oxynitride layer, a substrate is loaded into a reaction chamber having a first pressure and a first temperature. The oxide layer is formed on the substrate using a reaction gas while increasing a temperature of the reaction chamber from the first temperature to a second temperature under a second pressure. Additionally, the oxide layer is nitrified in the reaction chamber to form the oxynitride layer on the substrate. When the oxide layer and/or the oxynitride layer are formed on the substrate, minute patterns of a semiconductor device, for example a DRAM device, an SRAM device or an LOGIC device may be easily formed on the oxide layer or the oxynitride layer.
