METHOD OF PROTECTION AGAINST ELECTROSTATIC DISCHARGE IN DEVICE OF THREE-DIMENSIONAL (3-D) MULTILEVEL INTEGRAL CIRCUIT, DEVICE OF THREE-DIMENSIONAL (3-D) MULTILEVEL INTEGRAL CIRCUIT AND METHOD OF ITS MANUFACTURING Russian patent published in 2012 - IPC H01L25/65 

Abstract RU 2469434 C1

FIELD: electricity.

SUBSTANCE: device of a three-dimensional (3-D) multilevel integral circuit comprises first and second semiconductor crystals applied one onto another, multiple through transition holes, formed to pass substantially between active layers of the first and second semiconductor crystals and arranged as capable of providing connection between the first and second semiconductor crystals, and an active circuit formed at least partially inside at least one of many through transition holes, besides, the first and second semiconductor crystals jointly use an active circuit at least for protection against an electrostatic discharge.

EFFECT: invention makes it possible to save space and reduce area of a crystal required for a circuit of an ESD-protection.
