A Platform Technology for Producing Flexible Silicon Substrate

Technology Overview

This technology provides a futuristic approach for the electronics and gadgets industry. It takes on the challenge of manufacturing semiconductor substrates, such as silicon, in a flexible transparent form. We anticipate that this technology will revolutionize the industry of electronics and gadgets by providing entirely modern and futuristic flexible, smart-looking, and transparent devices and products with enhanced performance. All this can be done with even cheaper and low-cost manufacturing capabilities using conventionally known standard electronic manufacturing processes such as CMOS. 

Technology Features & Specifications

This technology follows a process that enables the production of flexible and transparent substrates such as monocrystalline silicon that can be used as a platform for semiconductor printing and wiring in electronic devices.

The process is cost-effective and can be made compatible with the conventional CMOS process. It involves various steps of oxidation, etching, implantation, and masking to create vertical channels across the substrate in a controlled manner. Once this has been achieved, anisotropic etching can be done smoothly before peeling off a thin layer of the substrate that can be monitored down to sub-micron levels in thickness. The resulting substrate from this technology has excellent properties of optical transparency, mechanical flexibility and strength. 

The only low-cost process that is capable of providing electronic substrates. The process is compatible with widely used CMOS process. It provides for effective usage of electronic substrates with excellent high-throughput and effective utilization and recyclability of substrate materials.

Potential Applications

The new platform technology leads to application areas that were not possible with conventional electronic processes. This is a revolutionary field showing numerous emerging technologies with high potential such as: 

  • Photovoltaics panels, lighting, displays
  • Ultra-mobile computation devices
  • Bio-integrated electronics, medical devices
  • Micro and nano membranes 
  • And wearable electronics components: medical devices, smart textiles

Customer Benefits
