Abstract
A method of manufacturing a microelectric device containing, on a substrate, a plurality of interconnected elements, comprising the steps of manufacturing on a substrate cells of elements, testing of the cells in order to distinguish the valid cells, formation of junction bands in an electrical conductive material connecting at least one valid cell, the junction bands being formed in fields, each field comprising an overlapping area with at least one neighboring field.
Claims10
A method of manufacturing and reconfiguration of a microelectronic device containing, on a substrate, a plurality of interconnected elements, comprising the steps of:
- (a) manufacturing cells on a substrate, each of the cells having at least one element, each of the cells being electrically isolated from each other, and at least one element of each of the cells having at least one connection terminal for interconnecting the cells according to a given connection plan;
- (b) testing the cells in order to distinguish cells having valid elements from cells containing at least one invalid element;
- and
- (c) forming junction bands in an electrical conductive material connecting at least one connection terminal of at least one element of a valid cell with at least one element of another valid cell, the junction bands being formed in valid, substantially identical fields, each valid field covering respectively a valid cell and comprising at least one marginal overlapping zone with at least one neighboring valid field, the overlapping zone comprising at least one portion of a junction band.
