Abstract : Investigation continued on the use of larger double-epitaxial slices for the milliwatt logic process, including the creation of special masks and handling equipment. In order to improve epitaxial film thickness and resistivity, a new reactor was installed, tested, and evaluated. More than twice as many slices are being produced with the new reactor. Assembly flow was improved by installing a two-unit magnetic heater on all bonding machines, adding a process for nickel and duplex gold plating headers to reduce discoloration, and implementing improved techniques for checking temperature and pressure on the bonding machine.
