Overview

Thin Film Electronics Standard Technology

Creating wafers with the TFE process will result in a chip with up to four layers: two polyimide layers and two metal layers.

Layer name Thickness (µm) Purpose
Metal 10.24 This layer is ideal for routing traces and defining electrode sites.
Top metal0.10 This layer is ideal for remetallizing electrode sites and connection pads.
Polyimide 15 This layer forms the base of the device.
Polyimide 25 This layer insulates the routing traces.
