Claim 14:
15. A method of bonding a plurality of chiplets onto a substrate, comprising:
loading a first type of substrate onto a first loadport of an equipment front end module (EFEM) of a multi-chamber processing tool having a plurality of atmospheric modular mainframes (AMMs);
using an EFEM robot to transfer the first type of substrate to a first buffer disposed in a first AMM coupled to the EFEM;
serially transferring the first type of substrate from the first buffer to a first wet clean chamber to perform a cleaning process, to a first degas chamber to perform a degas process to dry the first type of substrate, to a first plasma chamber to perform a plasma etch process to remove unwanted material form the first type of substrate, and to a bonder chamber;
using the EFEM robot to transfer a second type of substrate, having a plurality of chiplets, to the first buffer;
serially transferring the second type of substrate from the first buffer to a second wet clean chamber to perform a cleaning process, to a second degas chamber to perform a degas process to dry the second type of substrate, to a second plasma chamber to perform a plasma etch process to remove unwanted material from the second type of substrate, to a radiation chamber to perform a radiation process to weaken bonds between the plurality of chiplets and second type of substrate, and to the bonder chamber;
transferring at least some of the plurality of chiplets from the second type of substrate to the first type of substrate in the bonder chamber;
bonding the at least some of the plurality of chiplets to the first type of substrate in the bonder chamber; and
loading the first type of substrate with the bonded plurality of chiplets from a last AMM to a loadport of a second EFEM of the multi-chamber processing tool.
