Abstract

As a process for fabricating uniform patterns fine enough to produce a quantum size effect, the use of electron halography is proposed. Disclosed examples employing a process are methods of manufacturing a semiconductors laser whose threshold current is approximately 1 mA, and a permeable transistor and bistable device whose response rates are 100 GHz.
