Three-dimensional isotropic microfabrication in glass using spatiotemporal focusing of high-repetition-rate femtosecond laser pulses

Opto-Electronic Advances, 2023
To improve the processing efficiency and extend the tuning range of 3D isotropic fabrication, we apply the simultaneous spatiotemporal focusing (SSTF) technique to a high-repetition-rate femtosecond (fs) fiber laser system. In the SSTF scheme, we propose

Stepwise neuronal network pattern formation in agarose gel during cultivation using non-destructive microneedle photothermal microfabrication

Scientific Reports, 2021
Conventional neuronal network pattern formation techniques cannot control the arrangement of axons and dendrites because network structures must be fixed before neurite differentiation. To overcome this limitation, we developed a non-destructive stepwise

Artifact‐Minimizing Ultrathin Transparent Electrodes Fabricated via iCVD for In Vivo Optogenetic Stimulation and Neural Signal Monitoring of Primary Visual Cortex

Advanced Functional Materials, EarlyView.
We present ultrathin flexible transparent electrodes through iCVD‐enabled molecular control of 10 nm gold films on poly(dimethylaminomethylstyrene). In vivo validation demonstrated photoelectric artifact reduction vs. opaque electrodes and preservation of natural neural dynamics.

Metal-Assisted Etching of p-Type Silicon Using Patterned Platinum and Silver Films in Single Layers and Bimetal Double Layers

Electrochemistry
Metal-assisted etching (metal-assisted chemical etching) is a promising wet process for silicon (Si) microfabrication. The etching behavior depends on the catalyst metal, but detailed differences are not fully understood.

Microfabrication of Transparent Thermoplastic Resin Plates by Dry Etching

Journal of the Vacuum Society of Japan, 2009
This paper describes the microfabrication of transparent thermoplastic plates, polymethyl-methacrylate, polycarbonate, and cyclic olefin polymer by an electron cyclotron resonance-reactive ion etching (ECR-RIE) system. The system was adopted for the microstructure with smooth surface and high-aspect ratio.
