CONTACT FUSE WHICH DOES NOT TOUCH A METAL LAYER

摘要

The invention provides a semiconductor device fuse (100), comprising a metal layer (105) and a first semiconductor layer (110) that electrically couples the metal layer to a fuse layer (115), wherein the fuse layer is spaced apart from the metal layer. The semiconductor device fuse further comprises a second semiconductor layer (120) that forms a blow junction interface (125) with the fuse layer. The blow junction interface is configured to form an open circuit when a predefined power is transmitted through the second semiconductor layer to the fuse layer.
