Claim 11:
12. A substrate module, comprising:
a first substrate; and
a transistor unit disposed on the first substrate, wherein the transistor unit comprises:
an active layer, wherein the active layer has a first surface and a second surface, and the first surface is opposite to the second surface; and
a first electrode and a second electrode, wherein the first electrode and the second electrode at least partially overlap the active layer,
wherein the second surface contacts the first electrode and the second electrode,
wherein a first gallium concentration, a first zinc concentration, and a first indium concentration exist within a first range in the active layer, the first range is adjacent to the second surface of the active layer, a second gallium concentration exists within a second range in the active layer, the second range is adjacent to the first surface of the active layer, the first gallium concentration is higher than the second gallium concentration, and the first zinc concentration is higher than the first indium concentration.
