Publication number: 20230327019Abstract: Some embodiments include a ferroelectric transistor having a first electrode and a second electrode. The second electrode is offset from the first electrode by an active region. A transistor gate is along a portion of the active region. The active region includes a first source/drain region adjacent the first electrode, a second source/drain region adjacent the second electrode, and a body region between the first and second source/drain regions. The body region includes a gated channel region adjacent the transistor gate. The active region includes at least one barrier between the second electrode and the gated channel region which is permeable to electrons but not to holes. Ferroelectric material is between the transistor gate and the gated channel region.Type: ApplicationFiled: June 9, 2023Publication date: October 12, 2023Applicant: Micron Technology, Inc.Inventors: Kamal M.

Patent number: 11594611Abstract: Some embodiments include a semiconductor construction having a gate extending into a semiconductor base. Conductively-doped source and drain regions are within the base adjacent the gate. A gate dielectric has a first segment between the source region and the gate, a second segment between the drain region and the gate, and a third segment between the first and second segments. At least a portion of the gate dielectric comprises ferroelectric material. In some embodiments the ferroelectric material is within each of the first, second and third segments. In some embodiments, the ferroelectric material is within the first segment or the third segment. In some embodiments, a transistor has a gate, a source region and a drain region; and has a channel region between the source and drain regions. The transistor has a gate dielectric which contains ferroelectric material between the source region and the gate.Type: GrantFiled: February 19, 2021Date of Patent: February 28, 2023Assignee: Micron Technology, Inc.Inventors: Durai Vishak Ramaswamy, Kirk D.
