Assignee: INTEL CORPORATION
Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 14:
15. A system comprising:
a thin film transistor (TFT) structure, comprising:
a gate electrode;
a gate dielectric layer on the gate electrode;
a channel layer on the gate dielectric layer, wherein the channel layer comprises a semiconductor material with a first polarity and comprising a first metal and oxygen;
a multi-layer material stack on the channel layer, opposite the gate dielectric layer;
a dielectric material over the multi-layer material stack and beyond a sidewall of the channel layer;
a source and drain contacts through the dielectric material, and in contact with the channel layer, wherein the multi-layer material stack comprises:
a first layer comprising oxygen and a second metal, wherein the second metal is absent from the channel layer, wherein the first layer is in contact with the channel layer, and wherein the first layer has a second polarity, complementary to the first polarity; and
a second layer in contact with the first layer, wherein the second layer and the ILD dielectric material have a different composition; and

a memory element coupled with the drain contact.
