WebThis paper presents the 14 nm chip and package interaction (CPI) challenges and development by using 140 um minimum pitch with SnAg bump in a flip chip BGA package. We evaluated 14 nm back end of line (BEOL) film strength/structure/ adhesion with a large die size of 21x21 mm~2 and optimized bumping technology by passing all the CPI … WebCost is a factor in selection of integrated circuit packaging. Typically, an inexpensive plastic package can dissipate heat up to 2W, which is sufficient for many simple applications, though a similar ceramic package can …

WebOct 1, 2024 · It is attributed mainly to various combinations of the Chip-Package-Interaction (CPI) effects. This challenge is further amplified by the adoption of Cu Pillars to replace conventional solder bump flip chip interconnects as the device bump pitch shrinks and the demand for higher I/O counts per area soars. Furthermore, the adoption of Cu … cinesercla shopping cajazeiras
Chip-Package Interaction, Characterization and …
WebThe residual stresses generated during different processing steps and during thermal cycling of 3D stack packages, mimicking its service life, are quantified by Finite Element Modeling (FEM) together with measurements of dedicated FET arrays used as CPI sensors. Thermo-mechanical deformation of the package can be directly transferred to the Cu/low-k … WebMay 29, 2024 · In this work the focus is on thermo-mechanical aspects of Chip Package Interaction (CPI) in flip-chip Chip Scale packages (fcCSP) packages. To minimize mechanical stress induced during flip-chip process, the laminate substrate with very low coefficient of thermal expansion (CTE) of the core material (?5 ppm/°C) is used. … WebAug 12, 2024 · Within CTO, the Chip-Package Interaction team enables waferfab technologies to NXP Chip-Package Interaction requirements in assembly, test, and over product life through deep understanding of assembly and package induced stresses on IC chips, characterization, and definition of processes and design rules. cinesesc twitter
