Manufacturing method of bonded-substrate article, manufacturing method of liquid discharge head, bonded-substrate article, and liquid discharge head
First Claim
1. A manufacturing method for a bonded-substrate article where a first substrate has a first bonding region and a second bonding region that are both bonded to a second substrate, and the second substrate has a third bonding region and a fourth bonding region that are both bonded to the first substrate, the method comprising:
- first bonding, where the first bonding region of the first substrate and the third bonding region of the second substrate are bonded at a first temperature; and
second bonding, following the first bonding, where the second bonding region of the first substrate and the fourth bonding region of the second substrate are bonded at a second temperature,wherein the first temperature is lower than the second temperature.

Abstract
A manufacturing method for a bonded-substrate article includes a first bonding where a first bonding region of a first substrate and a third bonding region of a second substrate are bonded at a first temperature, and a second bonding, following the first bonding, where a second bonding region of the first substrate and a fourth bonding region of the second substrate are bonded at a second temperature. The first temperature is lower than the second temperature.
