Purpose of procurement
KTH is seeking tenders for a new hybrid thin film deposition system to be used for micro- and nanostructure fabrication.
The main application of the procured tool will be metallization of microelectronic circuits and hardmasks for etching using photoresist-liftoff techniques, making temperature control vitally important to avoid resist burning. Substrates will be mainly individual chips (possibly up to 80% of the usage) and wafers up to 4’’ diameter (remaining 20%), but with other new purchases and our recent push towards 4’’ processing, this ratio may shift in the near future. As requested by our user base and as a new capability for our lab, the system must come equipped with an ion gun for sample cleaning prior to deposition and low-energy ion-bombardment during evaporation for modified film properties.
