Method of manufacturing a capacitor including dielectric structure formed of sintered body

A manufacturing method for a capacitor, the capacitor comprising:

• a first substrate constituting a bottom surface of the capacitor, a second substrate constituting a top surface of the capacitor, a plurality of layer portions stacked in a first direction provided between the first substrate and the second substrate, wherein each of the plurality of layer portions includes:
• a dielectric structure formed of a sintered dielectric a first electrode formed of a conductor and a second electrode formed of a conductor,
• the dielectric structure includes at least one continuous wall,
• the first electrode and the second electrode are insulated from each other by the at least one continuous wall,
• the at least one continuous wall has a height and a thickness, the height being a dimension in the first direction, the thickness being a dimension in a second direction orthogonal to the first direction,
• the height is greater than the thickness,
• the at least one continuous wall has a non-straight shape when seen in the first direction,
• the first electrodes of the plurality of layer portions are electrically connected to each other, and
• the second electrodes of the plurality of layer portions are electrically connected to each other,
• the manufacturing method comprising a layer-portion formation step repeated for forming each of the plurality of layer portions stacked in the first direction, the layer-portion formation step including the steps of:
• forming the dielectric structure formed of a sintered dielectric including at least one continuous wall provided over the first substrate;
• wherein the at least one continuous wall has a height and a thickness, the height being a dimension in a first direction perpendicular to the first substrate, the thickness being a dimension in a second direction orthogonal to the first direction, the height is greater than the thickness, the at least one continuous wall has a non-straight shape when seen in the first direction;
• and
• forming the first electrode and the second electrode simultaneously by applying a conductor film to either side of at least one continuous wall after the formation of the dielectric structure such that the first electrode and the second electrode are insulated from each other by the at least one continuous wall
• wherein the first electrodes of the plurality of layer portions are electrically connected to each other, and
• the second electrodes of the plurality of layer portions are electrically connected to each other.
