Due to the uncertain situation with COVID-19, the organizing committee has decided to have COOL Chips 23 in a web fashion on April 15-17, 2020 instead of holding the conference at the original venue. We are making efforts to keep the program almost same as the past COOL Chips. Only the difference will be that the conference is held digitally. Let’s enjoy the conference as usual.

Registration fee (Updated)

Registration Fees include admission to the virtual symposium on Web, a copy of the proceedings (copies of speakers’ slides) of all plenary and technical sessions presented on April 15-17, 2020. All registration Fees include tax. We will send you a URL and password for the web conference on WebEX after you register with this conference.
