  • Patent number: 6387774
    Abstract: A method for patterning a layer of a microelectronic device includes the step of forming an etching mask on the layer to be etched opposite the microelectronic substrate. The etching mask defines exposed portions of the material layer and the etching mask has a notch in the sidewall thereof adjacent the material layer. The exposed portions of the material layer are then etched. More particularly, the step of forming the etching mask can include the steps of forming a first patterned mask layer on the layer to be etched and forming a second patterned mask layer on the first patterned mask layer wherein the second patterned mask layer extends beyond the first patterned mask layer thereby defining the notch in the sidewall of the etching mask.

  • Patent number: 6004882
    Abstract: A method for etching a platinum (Pt) layer of a semiconductor device is provided which improves the etching slope of a sidewall of the platinum layer used as a storage node of the semiconductor device. The semiconductor device consists of a semiconductor substrate including a bottom layer on which various other layers are formed. Specifically, according to this invention, a Pt layer is formed on a bottom layer of a semiconductor substrate. An adhesive layer is then formed on the Pt layer while a mask layer is formed on the adhesive layer. After formation of the various layers, the mask layer and adhesive layer are patterned using an etching process to form a mask pattern and an adhesive layer mask pattern, respectively. The semiconductor substrate is then heated and an etching process is performned on the Pt layer using the mask pattern and the adhesive layer mask pattern to form etching slope sidewalls of the Pt layer having etching slopes close to vertical.
