Patent number: 8138093Abstract: A lithographic material stack including a photo-resist and an organic planarizing layer is combined with an etch process that generates etch residues over a wide region from sidewalls of etched regions. By selecting the etch chemistry that produces deposition of etch residues from the organic planarizing layer over a wide region, the etch residue generated at the sidewalls of the wide trench is deposited over the entire bottom surface of the wide trench. An etch residue portion remains at the bottom surface of the wide trench when the organic planarizing layer is etched through in the first trench region. The etch residue portion is employed in the next step of the etch process to retard the etch rate in the wide trench, thereby producing the same depth for all trenches in the material layer into which the pattern of the lithographic material stack is transferred.Type: GrantFiled: August 12, 2009Date of Patent: March 20, 2012Assignee: International Business Machines CorporationInventors: Hakeem B.

Patent number: 8125053Abstract: A system, method, and apparatus for suppressing cracks in the wafer dicing process. A wafer includes a plurality of die attached to a frame and mounting tape, with the die separated by a plurality of scribe lanes. An existing die seal generally protects the boundary of the die but can still fail to fully protect the die from excessive cracks induced by dicing damage, particularly when dicing through brittle, low-k dielectrics. The system, method, and apparatus includes embedding a crack arrest structure (CAS) between adjacent scribe lanes. Upon a mechanical saw dicing the wafer, the CAS creates a moisture diffusion block, and can absorb or significantly diminish the energy of cracks propagating towards the individual die seals. Furthermore, the system, method, and apparatus can be implemented without the need to increase the width of the scribe lanes.Type: GrantFiled: February 4, 2009Date of Patent: February 28, 2012Assignee: Texas Instruments IncorporatedInventors: Jeffrey A.
