In this study, some properties of the source set of semiprimeness defined as $S_{S} = {\lbrace a\in S \mid aSa =(0)\rbrace}$ for the types semigroups S will be examined. The aim of this study is to get effective solutions to problems with generalizations and connections to be obtained in semigroup theory which is one of the important subjects of mathematics and especially algebra. In addition, investigating this subject in semigroup types will both add new definitions and theorems to the literature, and help establish the relationships between ring theory and semigroup theory.
