Patent number: 7252861Abstract: Multi-layer structures are electrochemically fabricated by depositing a first material, selectively etching the first material (e.g. via a mask), depositing a second material to fill in the voids created by the etching, and then planarizing the depositions so as to bound the layer being created and thereafter adding additional layers to previously formed layers. The first and second depositions may be of the blanket or selective type.

Patent number: 7252908Abstract: The present invention relates to an electrolytic solution for a lithium battery and a lithium battery using the same. The organic electrolytic solution includes a lithium salt, a mixed organic solvent comprising a high dielectric constant solvent and a low boiling-point solvent, and an additive. The additive used in the electrolytic solution is a heterocyclic compound of Formula (1): where R1, R2 and R3 may each independently be a C1-C10 linear or branched alkyl group; R4 may be a C1-C10 linear or branched alkylene group; X may be a heterocyclic ring containing N and O whereby a tetraallkyl orthosilicate functional group may be linked to N. The lithium battery using the organic electrolytic solution of the present invention is highly reliable and maintains a constant thickness during a charge/discharge cycle.Type: GrantFiled: September 27, 2004Date of Patent: August 7, 2007Assignee: Samsung SDI Co., Ltd.Inventors: Hansu Kim, Myung-Dong Cho, Hyo-Sug Lee, Boris A.
