    Abstract: Disclosed is a method for processing a two layer mask for use in fabrication of semiconductor devices whereby the critical dimension (CD) of a semiconductor device being fabricated with the mask can be controlled. After forming a carbon mask layer, preferably by a spin-on process, and a silicon containing photoresist layer on the carbon mask, a two-step process forms openings in the carbon mask layer, as required for subsequent device fabrication. The structure is placed in a plasma processing chamber, and an oxygen plasma is employed to partially etch the carbon layer. The oxygen plasma reacts with silicon in the photoresist to form a hard silicon oxide layer on the surface of the photoresist. A hydrogen plasma is then employed to complete the etch through the carbon layer with a reduced critical dimension.

    Abstract: Ferrocapacitors having a vertical structure are formed by a process in which a ferroelectric layer (33) is deposited over an insulator (31). In a first etching stage, the ferroelectric material is etched to form openings (35) in it, leaving the insulating layer substantially intact. Then a conductive layer (39) is deposited into the openings formed in the ferroelectric layer, forming electrodes on the sides of the openings. Further etching is performed to form gaps in the AI 2 O 3 layer (31), for making connections to conductive elements (3) beneath it. Thus, by the time the second etching step is performed, there are already electrodes overlying the sides of the ferroelectric material, without insulating fences in between.
