Abstract:
1. An oxidized low density lipoprotein sensing device for a gallium nitride process, which is a gallium nitride high electron mobility transistor (GaN HEMT) device, comprising: a gateless AlGaN/GaN sensing transistor device, being an epitaxial wafer structure having a GaN layer and an aluminum gallium nitride layer, and the aluminum gallium nitride layer being disposed on the GaN layer, and the aluminum gallium nitride layer including aluminum of a weight percentage and the aluminum gallium nitride layer having a thickness for achieving a lattice match; a testing window, disposed on the epitaxial wafer structure; a source, disposed at the epitaxial wafer structure and on a side of the testing window; a drain, disposed at the epitaxial wafer structure and on another side of the testing window; two metal connecting wires, disposed on the source and the drain respectively, and provided for taking a measurement; and a passivation layer, covered onto an external surface of the gateless AlGaN/GaN sensing transistor device except the testing window, for sensing the level of oxidizing proteins in a human body.
