Patent ID: 11923339
Assignee: YANGTZE MEMORY TECHNOLOGIES CO., LTD.
Field: Semiconductors (Electrical engineering)
Classification: CPC H  G | IPC H

Claim 4:
5. A method for forming a three-dimensional semiconductor device, comprising:
forming a first memory chip, comprising:
forming at least one first memory cell on a first substrate; and
forming a first interconnect layer on the at least one first memory cell;

forming a second memory chip, comprising:
forming at least one second memory cell on a second substrate; and
forming a second interconnect layer on the at least one second memory cell;

bonding the first interconnect layer of the first memory chip with the second interconnect layer of the second memory chip, such that the at least one first memory cell of the first memory chip is electrically connected with the at least one second memory cell of the second memory chip;
forming a microprocessor chip, comprising:
forming at least one microprocessor device on a third substrate; and
forming a third interconnect layer on the at least one microprocessor device; and

bonding the third interconnect layer of the microprocessor chip with the first substrate of the first memory chip, such that the at least one microprocessor device of the microprocessor chip is electrically connected with the at least one first memory cell of the first memory chip.
