Title: Method for forming contact plug in semiconductor device
Inventor: OH CHAN GWON
IPC: H01L21/283
Filed: 2000-06-30
Abstract: PURPOSE: A method for manufacturing a contact plug of a semiconductor device is provided to prevent a wordline insulation layer in a peripheral circuit region from being excessively lost, by making the depth of a plug in a cell region the same as the depth of a plug in the peripheral circuit region when the second contact plug is formed. CONSTITUTION: The first contact plug(24) is formed on a semiconductor substrate(21). Polysilicon for the second contact plug(25a) is formed on the entire surface including the first contact plug. The polysilicon for the second contact plug is selectively etched to form a contact hole of a bitline interconnection by using a damascene mask. The bitline interconnection filled in the contact hole for the bitline interconnection is formed. Etch targets in the cell region and the peripheral circuit region become the same to selectively etch the polysilicon for the second contact plug in a portion for the peripheral circuit region and the cell region. After a bitline insulation layer is formed on the resultant structure, the bitline insulation layer is chemical and mechanically polished until the bitline interconnection is exposed so that the completely-separated second contact plug is formed.
