Abstract: A field emission device (1) may be used for emitting electrons in, for example, a field emission display (FED). Field emission tips (40) are used for the emitting of electrons in the field emission device (1). In operation of the field emission device (1) a voltage is applied between a first electrode (4) having electrical contact with the field emission tip (40) and a second electrode (34) to make the field emission tip (40) emit electrons. To form a field emission tip (40) a layer of liquid material is applied on a substrate (2) provided with the first electrode (4). The layer of liquid material is embossed with a patterned stamp and subsequently cured to form a field emission tip structure (20). A conductive film (38) is applied on the field emission tip structure (20) to form a field emission tip (40) that has electrical contact with the first electrode (4).

Preferably, the salt is a salt of magnesium acetate. The compositions can be used to make temperature-resistant electrically-conductive silver-containing layers, for instance for use in AMLCD.

Abstract: A field emission device (100) is provided with a cathode electrode (120) and a gate electrode (140). Between these electrodes, a patterned dielectric layer (130) is provided. According to the invention, this dielectric layer (130) is manufactured from a liquid precursor material (131) which is patterned by means of a liquid embossing step, i.e. engaging a patterned stamp (150) with the liquid material (131). After removing the stamp (150), the liquid material is cured to form the patterned dielectric layer (130). Preferably, in a subsequent manufacturing step, the cathode electrode (120) or the gate electrode (140) is formed over the patterned dielectric layer (130) in a self-aligned way.
