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

Claim 7:
8. A method of manufacturing a semiconductor device, comprising:
forming a first insulator on a first substrate;
forming a first pad in the first insulator;
forming a second insulator on a second substrate;
forming a second pad in the second insulator; and
bonding the first substrate to the second substrate such that the second insulator is arranged on the first insulator, and the second pad is arranged on the first pad, wherein
the first insulator is formed to include a first film that is in contact with the first pad and the second insulator, and a second film provided at an interval from the first pad and the second insulator, and including a portion provided at a same height as at least a portion of the first pad, and
the second film includes polysilazane.
