Your university's engineering department must hold an active institutional membership with the respective aggregator.
Companies with an active foundry service agreement with TSMC can download the PDK directly from the TSMC Online customer portal. tsmc 65nm pdk download
Students, professors, and academic researchers rarely coordinate directly with TSMC. Instead, they access the 65nm PDK through regional non-profit silicon brokers and government-sponsored consortia: Muse Semiconductor or CMC Microsystems. Europe: Europractice.
