Yield improvement of a large area magnetic field sensor array design using redundancy schemes

Design of a Large Area Magnetic Field Sensor Array (LAMSA) using redundancy schemes concurrently with the laser link technology for fault repairs is presented. Experimental results obtained on a laser restructurable subarray of three magnetic field sensor cells are shown. An experimental yield measurement method to determine parameters of two yield detractors is described. These parameters obtained from regular sized VLSI chips are used to predict the yield of larger sensor array designs implemented with redundancy.
