摘要:An upper electrode of a capacitor has a two-layer structure of first and secondupper electrodes. A gate electrode of a MOS field effect transistor and a fuse areformed by patterning conductive layers used to form the lower electrode, first upper
electrode and second upper electrode of the capacitor. In forming a capacitor and a fuseon a semiconductor substrate by a conventional method, at least three etching masks areselectively used to pattern respective layers to form the capacitor and fuse before wiringconnection. The number of etching masks can be reduced in manufacturing a
semiconductor device having capacitors, fuses and MOS field effect transistors so thatthe number of processes can be reduced and it becomes easy to improve theproductivity and reduce the manufacture cost.
