Heterogeneous Integration Fabric

In the past five decades, the semiconductor industry has gone through two distinct eras of scaling: the geometric (or classical) scaling era and the equivalent (or effective) scaling era. As transistor and memory features approach sub-10 nanometer, it is apparent that room for further scaling in the horizontal plane is running out. Further, the rise of data abundant computing is exacerbating the interconnect bottleneck that exists in conventional computing architecture between the compute cores and the memory blocks. In this talk, I will discuss how electronics is poised to enter a new, third, era of scaling – hyperscaling – in which resources are added in a flexible way when needed to meet the demands of data abundant workloads. This era will be driven by advances in embedded non-volatile memories, hybrid devices with merged logic and memory functionalities, monolithic three-dimensional integration, and heterogeneous integration techniques.

August 6th, 2020: All-Printed Supercapacitors for In Space Manufacturing and Terrestrial Applications

All-Printed Supercapacitors for In Space Manufacturing and Terrestrial Applications

Dr. Myeonglok Seol, NASA Ames Research Center

Printing technology has evolved from traditional quick writing tools to the modern
manufacturing methods for functional devices and systems. The benefits of printing-based
manufacturing include less material waste, fast-turn around prototyping due to simple
design customization and wide substrate compatibility. In this presentation, all-printed
supercapacitors, where all the components are made by printing, are introduced. Because
the device is manufactured only by printing, the complexity of manufacturing facilities can
be minimized and the resource efficiency and versatility are maximized, which are
particularly important in places where the supply of material and human resources are
limited such as rural areas, environmental monitoring of nuclear sites and space exploration
missions. We have fabricated electrical double layer capacitors and pseudocapacitors, both
with high electrochemical performance and cyclic durability and the results will be discussed
in detail.

Quantitative Plasmonic Sensing with Single-Chip Inkjet Dispense Surface Enhanced Raman Spectroscopy (ID-SERS)

Dr. Fausto D’Apuzzo, Optical Scientist, HP Labs

Tues June 9

Noon-1:30PM Pacific Time, Virtual Meeting via Zoom

Register Here ! (Note: FREE to attend, but limited to 100 attendees! Registration ends at 10AM Pacific Time June 2nd.)



In this talk, I will present our Laboratory work on highly-quantitative plasmonic sensing based on Surface Enhanced Raman Spectroscopy (SERS). I will first describe our nano-imprinted SERS substrate architecture and performance. Then I will show how inkjet dispensing can be used in conjunction with SERS to encode each sensor with a calibration pattern of microdroplets (~30 pico-liters), with the aim of locally calibrating sensor performance. This way, we demonstrate that Measurement Uncertainty of the SERS signal can be reduced below 2%, which to our knowledge, is a new record for plasmonic sensing platform. Furthermore, the use of inkjet dispensing in combination with Raman mapping improves assay throughput (100-fold) and reduces sample volume consumption (105-fold) in an automated and reproducible fashion. Since this approach overcomes important practical hurdles, we believe that this work reignites interest in the potential commercialization of plasmonic-based chemical sensors.

Recent paper for reference:  A Generalizable Single-Chip Calibration Method for Highly Quantitative SERS via Inkjet Dispense.

In this talk, I will present our laboratory’s recent research efforts in rapid 3D bioprinting to create 3D tissue constructs using a variety of biomaterials and cells. These 3D biomaterials are functionalized with precise control of micro-architecture, mechanical (e.g. stiffness), chemical, and biological properties. Such functional biomaterials allow us to investigate cell-microenvironment interactions at nano- and micro-scales in response to integrated physical and chemical stimuli. From these fundamental studies we have been creating both in vitro and in vivo precision tissues for tissue regeneration, disease modeling, and drug discovery. To vascularize these engineered tissues, we have also developed a prevascularization technique by using the rapid 3D bioprinting method. Multiple cell types mimicking the native vascular cell composition were encapsulated directly into hydrogels with precisely controlled distribution.
As the Chair of the NanoEngineering Department, I will also discuss several cutting-edge research areas by our outstanding faculty.

Location: EAG Laboratories – 810 Kifer Road, Sunnyvale

Electron backscattered diffraction (EBSD) is a rapidly developing technique in the material characterization field. The technique gives microstructure information in the meso-scale which includes grain size, crystal orientation, grain boundaries, dislocations, and phase identification that all contribute to the device performance and reliability. Typical components that benefit from the EBSD analysis includes bond pads, solder joints, thin wires and capacitors. Electron channeling contrast imaging (ECCI) is a derivative technique from EBSD that gives quantitively defect density measurement of single crystals. The scanning area is on the order of several tens to hundreds of micrometers making this measurement ideal for high quality crystals (defect density 108/cm2 to 105/cm2).

Dr. Jingyi Zhang 
is an EBSD Scientist at EAG Laboratories, which she joined in 2018 after completing a doctorate in Mechanical Engineering at Washington State University. Her thesis was on mechanical and microstructural characterization of friction welds of dissimilar aluminum alloys. Previously she had earned an MS in Materials Science and Engineering at Iowa State University, and a BS in Materials Science at Tianjin University.

 Tremendous effort has been made in exploring novel channel materials to complement silicon for future nanometer-scaled transistors. Among the viable options, carbon nanotubes (CNTs) are a potential candidate due to their high mobility and injection velocity despite their ultra-thin body thickness of 1 to 2 nm. Although carbon nanotube field-effect transistors (CNFETs) enable high-performance and energy-efficient digital systems, there are challenges that have yet to be solved.

The demand for storing electricity is growing more rapidly than ever with the increased use of the mobile Internet of Things (IoT) devices and electric vehicles. Thus, safe and cost-effective batteries with high energy density are drawing significant interest in the field.
In this presentation, a sustainable method to develop battery electrode materials will be presented. By using biomaterials, a rod shape virus (M13 bacteriophage) or a cylindrical shape microbe (Escherichia coli, called as E. coli), the electrodes for lithium-based batteries were fabricated in an environmentally friendly way. Through the interaction between precursor ions and protein assemblies of virus molecules, a wide range of transition metal oxides nanowires has been synthesized at room temperature under aqueous synthesis conditions. Besides, microbes were used as a pore template to create an interconnected pore structure by using lengthy E. coli. These biotemplates are about one million times cheaper and are easier to remove than synthetic porogens such as silica or polystyrene beads.
The battery electrodes made in a bioinspired method have presented significant performance improvements in Li-ion batteries as well as Li-oxygen batteries. We believe that biomaterials driven material research can provide an efficient and environmentally benign way to build a high-performance device, in particular, next-generation energy storage system.
