  • Patent number: 12189299
    Abstract: A digital lithography system includes adjacent scan regions, exposure units located above the scan regions, a memory, and a processing device operatively coupled to the memory. The exposure units include a first exposure unit associated with a first scan region and a second exposure unit associated with a second scan region. The processing device is to initiate a digital lithography process to pattern a substrate disposed on a stage in accordance with instructions. The processing device is to further perform a first pass of the first exposure unit over a stitching region at an interface of the first scan region and the second scan region at a first time. The processing device is to further perform a second pass of the second exposure unit over the stitching region at a second time that varies from the first time by less than forty seconds.

  • Patent number: 9647138
    Abstract: A metal oxide semiconductor transistor includes a gate, a metal oxide active layer, a gate insulating layer, a source, and a drain. The metal oxide active layer has a first surface and a second surface, and the first surface faces to the gate. The gate insulating layer is disposed between the gate and the metal oxide active layer. The source and the drain are respectively connected to the metal oxide active layer. The second surface defines a mobility enhancing region between the source and the drain. An oxygen content of the metal oxide active layer in the mobility enhancing region is less than an oxygen content of the metal oxide active layer in the region outside the mobility enhancing region. The metal oxide semiconductor transistor has high carrier mobility.

  • Patent number: 8927330
    Abstract: Disclosed herein is a method for manufacturing a metal-oxide thin film transistor. The method includes the steps of: (a1) forming a gate electrode on a substrate; (a2) forming a gate insulating layer over the gate electrode; (a3) forming a metal-oxide semiconductor layer having a channel region on the gate insulating layer; (a4) forming a source electrode and a drain electrode on the metal-oxide semiconductor layer, wherein the source electrode is spaced apart from the drain electrode by a gap exposing the channel region; (a5) forming a mobility-enhancing layer on the channel region, wherein the mobility-enhancing layer is not in contact with the source electrode and the drain electrode; and (a6) annealing the metal-oxide semiconductor layer and the mobility-enhancing layer in an environment at a temperature of about 200° C. to 350° C.
