Patent ID: 11916169
Assignee: PLESSEY SEMICONDUCTORS LIMITED
Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 0:
1. An active matrix LED array precursor comprising:
a common first semiconducting layer comprising a substantially undoped Group III-nitride;
a plurality of transistor-driven LED precursors, each transistor-driven LED precursor comprising:
a monolithic light emitting diode (LED) structure comprising a plurality of III-nitride semiconducting layers, each monolithic LED structure formed on a portion of the common semiconducting layer;
a barrier semiconducting layer formed on a portion of the common semiconducting layer encircling the LED structure configured to induce a two-dimensional electron channel layer at the interface between the common semiconducting layer and the barrier semiconducting layer; and
a gate contact formed over a portion of the two-dimensional electron channel layer, the gate contact encircling the LED structure; and

a common source contact configured to form an ohmic contact to each two-dimensional electron channel layer such that a high electron mobility transistor is provided between the common source contact and each monolithic LED structure for driving each LED structure.
