The Test Spring School (TSS) is the main international event where Ph.D. and M.Sc. students can learn about the leading-edge semiconductor test technology. It is organized in conjunction with ETS, taking place during the three days prior to the kick-off of ETS. Traditionally, renowned experts from academia and industry guarantee an exciting technical program introducing into the challenges of dependability, test and diagnosis. TSS will be a fully in-person event this year (no hybrid). As in previous years, TSS will give the students the opportunity to earn credits and a certificate by passing an online exam. To maintain the typical TSS atmosphere and support interaction during the event, the number of participants is strictly limited to 30 on a first-come first-serve basis. TSS also welcomes participation of academic and industrial professionals at a higher registration rate.
