    摘要: A method for protecting extraction electrodes (140) during processing of Spindt-tip field emitters (150, 155) includes the steps of: (i) depositing a parting layer (170) on the extraction electrodes (140) and in an interspace region (145) defined by the extraction electrodes (140), (ii) sharpening the Spindt-tip field emitters (150), (iii) depositing a layer (180) of emission-enhancing material on the sharpened field emitters (155) and on the parting layer (170), and (iv) removing the parting layer (170), thereby lifting off the emission-enhancing material from the extraction electrodes (140) and from the interspace region (145), but not from the sharpened field emitters (155).

    摘要: A mask (12) is applied to a silicon carbide substrate (11) in order to etch the substrate (11). The material used for the mask (12) has a Mohs hardness factor greater than 4 in order to prevent sputtering material from the mask (12) onto the substrate (11). An oxygen and sulfur hexafluoride plasma is utilized to perform the etch.
