Patent number: 7643268Abstract: Disclosed are embodiments of a capacitor with inter-digitated vertical plates and a method of forming the capacitor such that the effective gap distance between plates is reduced. This gap width reduction significantly increases the capacitance density of the capacitor. Gap width reduction is accomplished during back end of the line processing by masking connecting points with nodes, by etching the dielectric material from between the vertical plates and by etching a sacrificial material from below the vertical plates. Etching of the dielectric material from between the plates forms air gaps and various techniques can be used to cause the plates to collapse in on these air gaps, once the sacrificial material is removed. Any remaining air gaps can be filled by depositing a second dielectric material (e.g., a high k dielectric), which will further increase the capacitance density and will encapsulate the capacitor in order to make the reduced distance between the vertical plates permanent.Type: GrantFiled: August 20, 2008Date of Patent: January 5, 2010Assignee: International Business Machines CorporationInventor: Anil K.

Patent number: 7576968Abstract: A multilayer electronic component includes a plurality of dielectric layers interleaved with a plurality of internal electrodes. Internal and/or external anchor tabs may also be selectively interleaved with the dielectric layers. Portions of the internal electrodes and anchor tabs are exposed along the periphery of the electronic component in respective groups. Each exposed portion is within a predetermined distance from other exposed portions in a given group such that termination structures may be formed by deposition and controlled bridging of a thin-film plated material among selected of the exposed internal conductive elements. Electrolytic plating may be employed in conjunction with optional cleaning and annealing steps to form directly plated portions of copper, nickel or other conductive material. Once an initial thin-film metal is directly plated to a component periphery, additional portions of different materials may be plated thereon.Type: GrantFiled: August 10, 2006Date of Patent: August 18, 2009Assignee: AVX CorporationInventors: Andrew P.
