Patent ID: 11916022
Assignee: TAIWAN SEMICONDUCTOR MANUFACTURING COMPANY LTD.
Field: Semiconductors (Electrical engineering)
Classification: CPC H  G | IPC G  H

Claim 0:
1. A semiconductor processing system, comprising:
a bonding device configured to perform a bonding process that bonds a first wafer to a second wafer, wherein the bonding device comprises a plurality of wafer pins configured to mechanically-align the second wafer over the first wafer before performing the bonding process;
an overlay (OVL) shift measurement device configured to determine an OVL shift between the first wafer and the second wafer, whcrcin the sccond wafcr ovcrlics the first wafer;
a photolithography device configured to perform one or more photolithography processes on the second wafer; and
a controller configured to perform an alignment process on the photolithography device according to the determined OVL shift, wherein the photolithography device performs the one or more photolithography processes based on the OVL shift.
