Method of producing vertical interconnects between thin film microelectronic devices and products comprising such vertical interconnects

A method of producing a vertical interconnect between a first and second thin-film microelectronic device, wherein a vertical interconnect area is provided which is an area of overlap of a stack of layers comprising a first electrically conducting area, an organic electrically insulating area, a second organic electrically conducting area, and optionally an organic electrically semiconducting area, said layers of said stack being formed one by one, and at least one of said first or said second electrically conducting areas being positioned adjacent to and after said organic electrically insulating area, said first electrically conducting area being electrically connected to a terminal of said first thin-film microelectronic device and second organic electrically conducting area being electrically connected to a terminal of said second thin-film microelectronic device, characterized in that

• said organic electrically insulating area comprises photoresist material,
• said insulating area is removed within said area of overlap before said adjacent first or second electrically conducting area is positioned, and
• said removed insulating area is substituted by an electrically conducting area which is extended from at least said first or said second electrical conducting area, thereby forming the vertical interconnect;
• wherein an outer part outside of said area of overlap is maintained as an electrically insulating area.
