Thermomigration of non-oriented aluminium-rich liquid zones through (110) silicon wafers by Оlекsіі Polukhin, Vitalii Kravchina

“…It is shown that in the manufacture of semiconductor chips with a large perimeter and a reverse voltage of 2000 V, the conditions sine qua non to create isolating walls on silicon wafers with an orientation different from (111) are to form an ensemble of linear zones by the method of high-temperature selective forced wetting (HSV) and to fulfill a number of requirements to the “thermomigration” photomask and zones immersion stage during TM at high temperatures. …”
