Abstract | As the progression of 45/40nm ELK devices into mainstream semiconductor assembly manufacturing process increases, the drive to achieve adoption without major changes to process and equipment infrastructure while meeting the superior yield necessary is high. The main goal of this article is to share learning's and provide solutions for integration of 45/40nm ELK devices into Flip Chip and Wire Bond interconnect technology. The scope of this paper covers from FBGA/PBGA for the WB packages and fcCSP for the Flip Chip Devices. The main challenge and focus point for wire bond 45/40nm interconnects is on the $1^{st}$ bond process. This paper will share some detailed analysis on the following: ✓ WB characterization for 45/40nm ELK ultra-fine-pitch ✓ Key factors for good ball bond integrity and comparison of Au and Cu wire bond process ✓ Recommendations for achieving the required levels of reliability for 45nm Cu ELK integration. The challenges however, for Flip Chip technology are significantly different from the WB process. More and more adoption is being made from conventional eutectic solder bumps or high-lead solder bumps towards the lead-free solder bumps mainly due to the green initiatives. This paper will share analysis on the following: ✓ Thermo-Mechanical Simulation on key input factors and its correlation to actual evaluation results. ✓ Integration of Pb Free ELK Bump with 40nm ELK technology with focus on the critical reflow process. ✓ MUF Technology for Pb Free + ELK devices |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
