Prospects for new measurements using advanced silicon technologies in ALICE

<!--HTML-->A Large Ion Collider Experiment plans intensive use of silicon technologies for extensions of the experiment, beyond the currently ongoing upgrade during the Long Shutdown 2 of the LHC. For Run 4, we will discuss the plans for the installation of three new layers of the Inner Tracking system, based on wafer-sized sensors sufficiently thinned to be rolled to a cylinder. This will lead to an unprecedentedly low material budget, and consequently drastically reduced interaction probabilities and unparalleled vertexing performance. For Run 5 and beyond, we will present ideas for a next-generation heavy-ion experiment fully based on silicon sensors for tracking, time-of-flight and shower measurements. This combines the advantages of extremely low material budget, fast read-out and high resolution.
