"The equipment used in IMEC’s facilities is essentially the same equipment as used in commercial high-volume fabs. If 4DS demonstrates their memory technology is manufacturable at IMEC’s facilities, using commercially available state-of-the-art semiconductor equipment, the company can then engage in commercial discussions with potential licensees or strategic partners.Migrating from lab to fab is not simply copy/pasteFor 4DS, the key point of working with IMEC is (i) to develop a transferable production-compatible process flow for its Interface Switching ReRAM technology, (ii) to demonstrate this process on IMEC’s megabit test chip, and (iii)to collect statistically significant and meaningful data on yield, speed, endurance and data retention for high-volume memory makers to base the ir licensing or acquisition decisions on. But fabricating memory cells in an R&D lab is very different from manufacturing multiple wafers using state-of-the-art semiconductor manufacturing equipment at IMEC, let alone manufacturing in a commercial setting where processing speed and up-time is essential."

"4DS’ design to be mounted on IMEC’s megabit memory vehicle
Once 4DS and IMEC complete the memory technology transfer to300mm commercially available semiconductor manufacturing tools, the next step will be to mount this memory technology on IMEC’s standard megabit memory vehicle with all the required circuitry to connect memory cells using 4DS’ interface switching ReRAM technology to the outside world."

"Compared to transferring the core chip design from lab to fab, integrating this design with IMEC’s megabit memory vehicle should be relatively straightforward given IMEC has done this numerous times and the platform is a standard design. It will require some rigorous testing, though, specifically for yield, speed, endurance and retention. With all memory cells in a memory chip, they are accessible and testable at standard memory speeds –rather than individually as is the case in 4DS’ lab setting."

"Whoever licenses or buys the technology will likely want to further fine-tune the technology for specific applications. E.g. a memory manufacturer will want to tweak the technology further to suit a specific memory application, such as data-center orsmart phone.However,this further fine-tuning is beyond 4DS’ current scope of workas the company envisions any prospective licensee or acquirer will conduct their own final tweaking of the technology."
