In a semiconductor integrated circuit a programmable element comprises an aluminium track (15b) disposed between glass insulator layers (14, 16) and adjacent a polysilicon heater (13). Passage of a current through the heater causes reaction of the aluminium with the glass to provide a permanent open circuit condition. In a modification of this technique the aluminium track may be short circuited to the heater on the application of heat. The structure may be used e.g. in an uncommitted logic array. <IMAGE> |
