IPC: H01L21/28
Filed: 2000-10-11
Abstract: PURPOSE: A method for fabricating a contact hole of a semiconductor device is provided to reduce fabricating cost, by forming a fine contact hole fabricated in inexpensive exposure equipment without using expensive exposure equipment. CONSTITUTION: An interlayer dielectric(2) is formed on the first layer(1) like a semiconductor substrate, a metal interconnection or polysilicon. A photoresist layer is applied on the interlayer dielectric, and an exposure process is performed by using a mask of which the diameter is large as compared with a design. The photoresist layer is developed to form a photoresist layer pattern. After an insulation layer is formed on the resultant structure, a dry etch process is performed to make the insulation layer left only on the sidewall of the photoresist layer pattern. The exposed interlayer dielectric under the photoresist layer pattern and the sidewall of the photoresist layer pattern is etched by using as a mask the insulation layer left on the photoresist layer pattern and on the sidewall of the photoresist layer pattern. The insulation layer left on the photoresist layer pattern and on the sidewall of the photoresist layer pattern is eliminated. The fine contact hole corresponding to the diameter of the design is formed.
