Reduction of damage to a semiconductor device due to a marking process while inhibiting deterioration of a mark can not be achieved in conventional processes for manufacturing semiconductor devices. Said tubular elements of the sole are placed according an open annular path, with two tubular elements disposed in correspondence of a respective end of the open annular path and communicating with the outside of the sole. More specifically, ICIER increase the ionization efficiency of cysteine-containing peptides by attachment of a guanidino functional group. The effects processor includes a serial bus interface which communicates with the Serial Bus of a compact printer system comprising one or more further modules.
