Focused Ion Beam, or FIB circuit edit services allow the customer to cut traces or add metal connections within a chip. Our services include sample preparation, sample analysis, fault isolation, and actual circuit modifications. These circuit edits could support basic electrical design characterization or verification of redesign parameters. Our full range of debug tools enables you to solve even the most vexing logic failures and other anomalies.
FIB circuit edit employs a finely focused Ga+ ion beam to image, etch and deposit materials on an integrated circuit. The beam 4-5 nm resolution allows for extremely precise edits to be made. The FIB is coupled to a navigation system (Knights/Camelot/Lavis) providing a method to find subsurface features and ensuring that the right edits are made. The high energy Ga beam can mill through conductors and, by utilizing the appropriate gas chemistries; tungsten, platinum or silicon dioxide can be precisely deposited using the ion beam.
Focused ion beam circuit edits can be done quickly and easily, at a small fraction of the cost of a new lot of wafers in a fab. Circuit edits are often performed once a design flaw has been identified, to ensure that the proposed fix will solve the complete problem. With our state of the art equipment and specialized techniques, we can edit circuits at advanced process nodes such as 28nm, 20nm and 14 nm with multiple layer metal stacks as well as back side editing for flip chip packages. Our electronics engineers have many years of experience throughout Silicon Valley and have the knowledge and capability necessary to accommodate the most demanding requests. FIB edits often require rapid turnaround and cannot afford mistakes – our years of experience and focus on customer satisfaction make EAG the smart choice in circuit editing.
EAG’s FIB circuit edit services include the following processes, all of which can be performed with approximately 20nm accuracy:
These capabilities allow FIB to perform some key functions:
