ABSTRACT:
An enhancement implant used in late programming of a ROM in an integrated circuit is combined with a depletion implant used much earlier in the fabrication process to also permit late programming of power paths in the integrated circuit. The implants must be matched and the IC heated after the enhancement implant.
