Foldable layered connection, and method for manufacturing a foldable layered connection

A method for manufacturing a foldable layered connection (500) on a substrate (502), the method comprising:

• providing a substrate (502) having a first major surface (504) and an opposing second major surface (506);
• providing a first layer of sacrificial material (508) over the first major surface (504);
• providing a first layer of flexible material (516) over the first layer of sacrificial material (508), thereby at least partially encapsulating the first layer of sacrificial material (508);
• providing an opening in the first layer of flexible material (516), thereby exposing at least a portion of the substrate (502);
• providing a first layer of connector material (518) over the first layer of flexible material (516) and the substrate (502), the first layer of connector material (518) being in contact with the substrate (502), thereby forming a first contact of connector material and a node of connector material (520);
• providing a second layer of flexible material (522) over the first layer of connector material (518), the second layer of flexible material (522) being in contact with the first layer of flexible material (516), thereby at least partly encapsulating the first layer of connector material (518);
• exposing at least a portion of the first layer of connector material (518), thereby forming a second contact of connector material (524);
• and
• removing the first layer of sacrificial material (508) and a portion of the substrate (502), thereby forming a released extension (526) which is foldable towards the second major surface of the substrate (506), the released extension (526) comprising at least part of the first and second layer of flexible material (516, 522), and the at least partly encapsulated first layer of connector material (518).
