Title:
SEMICONDUCTOR DEVICE, AND MANUFACTURING METHOD FOR SEMICONDUCTOR DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/003047
Kind Code:
A1
Abstract:
Provided is a semiconductor device enabling high integration. Specifically provided is a semiconductor device which has a transistor, an interlayer film, and a first conductor, and in which: the transistor is provided with an oxide upon a first insulator, a second conductor upon the oxide, a second insulator provided between the oxide and the second conductor and provided in a manner touching the side surfaces of the second conductor, and a third insulator provided to the side surfaces of the second conductor, with the second insulator sandwiched therebetween; the oxide has a first region, a second region, and a third region; the first region overlaps with the second conductor; the second region is provided between the first region and the third region; the third region has a lower resistance than the second region; the second region has a lower resistance than the first region; the interlayer film is provided upon the first insulator and upon the oxide; the first conductor is electrically connected to the third region; the third region overlaps with any one among the third insulator, the first conductor, and the interlayer film; and the top surface of the third insulator is aligned with the top surface of the interlayer film.
