Work History
Senior Module Development Engineer
Intel Foundry
08.2022 - Current
In charge of Pathfinding and Module Engineering roadmap execution, playing a leading role inside laser and lithography module to develop next generation vertical Cu- interconnect technology development for high performance AI computing
Developed integrated process flow for multiple NPI lots with a strong cross-functional knowledge of design tradeoff, reliability checkpoints and the integrated assembly flow and their interdependence i.e. metallization, plating, lamination, CMP, laser and lithography loop, flip chip packaging, die attach, epoxy and thermal compression bonding etc.
Led the equipment and rapid process development of two first-of-a-kind laser tools from inception to HVM tracking milestone i.e. supplier audit, NPI and final tool qualification to semi-HVM operations
Managed multiple suppliers from different geographical areas i.e. Taiwan, Japan, Korea, Germany and USA
Steered the process development effort for the Bessel beam picosecond laser tool to handle wide range of substrate thickness and size for hyper large form factor substrates for advanced AI applications
Leading three very forward-looking projects: (i) industry’s most advanced excimer laser tool development with a target of 1um overlay (ii) Laser induced selective surface activation and plating project to reduce layers and attain zero misalignment bump and (iii) dual damascene process to replace traditional lithography loop with mask-based excimer laser
Conducted multiple DOEs to architect test vehicles for advanced laser recipe development for multi-stack dielectric layers with precision alignment compensation for next-gen EMIB-T technology development
Manufactured the key patterning features (i.e. Blind/Buffer via, TGV, fiducial, unit level traceability mark, Cavity and bridge via) by laser recipe development extracting design collaterals using DFX and ODB packages
Navigated design tradeoff by conducting test, DFX review and provided valuable inputs to the design team during the design rule scoping for final package layout and floor plan architecture to improve thermal and mechanical reliability
Translated system level product package requirement to module level and engineered the way to circumvent different manufacturing challenges which affects the thermal, mechanical, chemical and electrical performance of the package
Led the effort of gaining insight into glass processing and chemical strengthening with glass substrate suppliers and completed hands-on DOEs involving i.e. low and high CTE glass- to resolve system level product failure and reliability
Designed and developed test wafers and coupons for refractive index study in glass using ellipsometry and analyzed evolution of TGV, LAZ area and photo-elastic stress mapping to seamless connect with co-packaged optics
Received three times department level recognition for equipment qualification ramp to HVM and highest utilization
Patents: 3 patents granted for filing by Intel patent review committee
Research Associate
Advanced Materials & Manufacturing Lab, ASU
05.2019 - 07.2022
Maneuvered NSF funded research project on the materials development and scaling of the dynamic viscosity of metal-polymer matrix composite (PLA and Ni-Cu alloy) system to resolve critical manufacturing challenges of Injection molding/extrusion to produce highly dense 3D printed metal parts
Architected a completely new type of composite using capillary infiltration of polymers in metal nano-pores via low-cost 3D printing technology, technology which can be used to make low-cost 3D printed battery electrodes
Patents: 2 granted patents from PhD research and another new patent recently filed
