Vertex identification is one of the crucial tools in reconstructing particle physics collision events. The corresponding detectors come with some of the most demanding requirements, being close to the primary interaction point with a high track density, and stringent requirements on efficiency and precision. 

At a future lepton collider, as suggested by the European strategy update for particle physics, precision physics will allow to further dive into the properties of the Standard Model and possible extensions. However, the corresponding detector requirements enabling these measurements surpass these of the current LHC detectors by an order of magnitude in resolution, material budget and timing constraints. 

A particularly well-suited technology to tackle the task of designing such a detector are monolithic active silicon pixel sensors, which allow to combine the sensing volume and its front-end electronics in the same thin layer of silicon. This seminar will provide an overview of ongoing efforts in designing a vertex detector for a future lepton collider, dive into the different technology options for silicon sensors current available, and will sketch the road ahead.
