Then, a portion of the first dielectric layer is removed to form a contact hole. A conductive plug is formed within the contact hole. A seed layer is formed on the conductive plug. A sacrifice layer is formed on both the seed layer and the first dielectric layer. A predetermined region of the sacrifice layer is removed to form a recess so as to expose the seed layer.

摘要： A process for fabricating a fin type, cylindrical shaped, DRAM capacitor structure, with increased surface area, has been developed. The process features forming a non-continuous layer of discrete regions of silicon, on the surface of a capacitor opening, in a composite insulator layer. The discrete regions of silicon are then used as an etch mask to allow an isotropic etching procedure to create horizontal channels in the sides of the portions of the composite insulator layer exposed in the capacitor opening, creating a capacitor opening comprised with horizontal channnels. An amorphous silicon layer is then deposited and patterned to form a fin type, storage node structure, comprised of amorphous silicon on discrete regions of silicon, in the capacitor opening. Formation of a capacitor dielectric layer, and an overlying top electrode structure, complete the formation of a fin type, cylindrical shaped, DRAM capacitor structure.

摘要： A method for fabricating an interlayer dielectric layer on a semiconductor substrate with a memory cell region and a periphery circuit region is described, wherein semiconductor devices are formed on the memory cell region and the periphery circuit region so as to result in a height variation therebetween. The present method comprises the steps of forming a first dielectric layer blanket-covering the semiconductor substrate, wherein a first height variation exists between the memory cell region and the periphery circuit region. Then, a stop layer is conformally blanket formed on the first dielectric layer. Next, a second dielectric layer is conformally formed on the stop layer. A chemical mechanical polishing process is executed on the second dielectric layer until the stop layer on the memory cell region is exposed. This formation of the structure of a first dielectric layer/stop layer/second dielectric layer is repeated at least two times to achieve a planarized interlayer dielectric layer. A cap layer is formed on the top surface of the planarized interlayer dielectric layer.
