PRINTHEADS WITH EPROM CELLS HAVING ETCHED MULTI-METAL FLOATING GATES

摘要

In one example in accordance with the present disclosure a printhead with a number of EPROM cells is described. The printhead deposits fluid onto a print medium. The printhead also includes a number of EPROM cells. Each EPROM cell includes a substrate having a source and a drain disposed therein, a floating gate separated from the substrate by a first dielectric layer. The floating gate includes a multi-metal layer that is a metal etched layer. Each EPROM cell also includes a control gate separated from the multi-metal layer of the floating gate by a second dielectric layer.
