The electrically conductive carrier of the semiconductor into which the donor impurity is doped is mainly the electron in the conduction band, and the semiconductor into which the acceptor impurity is doped is of hole type conduction. Semiconductor degreasing agent is a key material used for removing photoresist in semiconductor manufacturing, and its performance directly affects the device yield and process efficiency.
