摘要： The present invention relates to a method for forming a VIA in an Inter Metal Dielectric (IMD) containing Spin On Glass (SOG). The IMD is formed by 1) depositing a first silicon dioxide layer through a Chemical Vapor Deposition (CVD) process; 2) depositing a Spin On Glass (SOG) layer; and 3) depositing a second silicon dioxide layer through a Chemical Vapor Deposition process. Afterward, before the VIA is formed by an Inter Metal Dielectric (IMD) etching process, a selective ion implantation process is performed to densify the Spin On Glass(SOG) layer. By this arrangement, the outgassing effect of the Spin On Glass (SOG) during a subsequent metal deposition process can be therefore prevented.

摘要： The present invention relates to a stacked capacitor of a DRAM cell, particully remarkably increasing a surface area of a storage electrode of a stacked capacitor without increasing an occupation area and a complexity of fabrication thereof. According to the invention, by use of depositing a protection polysilicon layer on a rugged polysilicon layer, which can provide an increased surface area of a storage electrode, a chemical oxide layer underlying the rugged polysilicon layer is protected by the protection polysilicon layer during a HF dip and thus a peeling of the rugged polysilicon layer as a result of the chemical oxide loss will not occur, thereby preventing a production yield loss.

摘要： The present invention relates to a rugged stacked oxide layer structure which remarkably increases an area of a subsequent deposition layer over the rugged stacked oxide layer. The enlargement of the area of a deposition layer over the rugged oxide layer enables one to ameliorate an electrical characteristic of a device and provide a higher integration density. For example, the rugged stacked oxide layer can be used to provide a higher capacitance by enlarging the area of a storage electrode of a capacitor. Similarly it can also be used to increase light absorption of a photodetector per unit area by enlarging an interfacial area of a P-N junction of the photodetector.

摘要： The present invention relates to a stacked memory capacitor of a DRAM cell, particularly, relates to a DRAM cell having a memory capacitor whose storage electrode possesses a remarkably increase area without increasing its occupation area and the complexity of fabrication thereof. By disposing the storage electrode of the memory capacitor on a rugged stacked oxide layer, the area of the storage electrode is remarkably enlarged since the growing of the storage electrode made of a doped polysilicon layer is followed along the topography of the rugged stacked oxide layer, thereby, resulting in a rugged surface thereof. The entire rugged surface of the storage electrode is covered with a dielectric layer to form a plate electrode made of a doped polysilicon layer. The memory capacitor provided by the invention achieves a higher capacitance while maintaining the same occupation area and packing density as that of the conventional arts.

摘要： A system and method for modifying an integrated circuit (IC) layout includes performing a correction process, such as an optical proximity correction (OPC) process, only on regions within designated blocks that are defined around respective modified structures. An IC layout can be compared to a modified version of the IC layout to detect modified structures. One or more large blocks can then be defined around respective modified structures. A correction process can then be performed on only the one or more large blocks. Small blocks within respective large blocks can then be extracted from the modified IC layout and merged with the original IC layout to generate a final modified and corrected IC layout.
