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

Claim 0:
1. A voltage regulator comprising:
an input node to receive an input voltage;
an output node;
a voltage regulator circuit to receive the input voltage at the input node and generate a regulated output voltage at the output node, wherein the voltage regulator circuit includes a thin-film transistor (TFT);
wherein the TFT includes a channel layer that includes an oxide semiconductor material, wherein the channel layer includes a dopant; and
wherein the dopant includes a concentration gradient within the channel layer, wherein a higher concentration of the dopant is at a side of the channel layer proximate to a source or a drain of the TFT, and wherein an entirety of a bottom of the channel layer is in a same plane, and wherein the channel layer is a back end of line channel layer, wherein the TFT is over one or more back end of line interconnect layers, and wherein the one or more interconnect layers are over a front-end transistor.
