Abstract

PURPOSE: To improve the current closing to the stripe domain and lower the operating current, by providing the current block domain in advance to the part in which the stripe is not formed on the semiconductor base of the first conduction type, and providing the second conduction layer on this and the active domain to the part in which stripe is formed.
