Abstract: PURPOSE: A method for forming a bit line contact hole of a semiconductor device is provided to maximumly control corrosion of a nitride layer constituting a cap layer and a sidewall spacer which cover a gate electrode layer, by performing an etch process for forming a bit line contact hole in an etch condition in which selectivity of the nitride layer is not lower than an etch condition of a self-aligned contact hole. CONSTITUTION: The gate electrode(108) capped with the nitride layer is formed on a semiconductor substrate(100), and a self-aligned contact hole is opened. A polysilicon contact plug is formed inside the open self-aligned contact hole. An oxide layer(114) is applied on the semiconductor substrate having the contact plug. A photoresist pattern for a bit line contact is formed on the oxide layer. The oxide layer is etched by using the photoresist pattern as an etch mask in an etch condition in which the selectivity of the nitride layer is not lower than the etch condition of the self-aligned contact hole.
