    摘要: A method for increasing landing pad area is disclosed. Firstly, providing a fundamental structure, wherein shallow trench isolation (STI) is used and acting as an electrical isolation inside of substrate. Moreover, there are at least two gates with an isolation layer on top of the substrate and covered with a dielectric layer. Between the neighboring gates there is a contact hole that penetrates the dielectric layer from the top of the dielectric layer to the substrate. Taking this fundamental structure as the starting point for forming a conductor within the contact hole. Etching back the dielectric layer and exposing its top surface and a portion of sidewalls. Finally, a protection layer on top of the exposed portion of sidewalls of the conductor is formed in order to expand the landing pad area. After all, one would still be able to increase the landing pad area even though the distance between two gates is rather small. This method can solve all the puzzles caused by alignment accuray shift during post-process.

    摘要: A method of making contact openings for memory cell units of DRAM IC devices is disclosed. The contact opening is used to connect the cell transistor source/drain terminal to the storage capacitor electrode located substantially above. The method includes the step of first patterning the initial opening in a shielding layer for the contact opening. The diameter of the initial opening is then reduced by the formation of sidewall spacers in initial opening. The initial opening in the shielding layer is then used to implement the etching for the formation of the contact opening. Due to reduced size of the contact opening, short-circuiting situations arising between the via formed in the contact opening and the bit lines next to the via as a result of misalignment in the process of fabrication can be reduced, thereby improving the device fabrication yield rates.

    摘要: A method is provided for use on a DRAM (dynamic random access memory) device for forming a data storage capacitor with a wide electrode area, and thus a high capacitance, for the DRAM device. The high capacitance allows the data storage capacitor to preserve high data retaining capability when the DRAM device is downsized for high integration. The method is characterized in the forming of silicon-nitride based sidewall spacers in openings formed in oxide layers that allows the subsequently formed contact window to be formed with a reduced width, thereby preventing the subsequent etching process to damage the nearby polysilicon-based bit lines and gate electrodes due to misalignment in the etching. Moreover, the method allows the resultant data storage capacitor to have a wide electrode area that helps increase the capacitance thereof, thereby allowing the DRAM device to preserve a high and reliable data retaining capability to the data stored therein.
