Provided is a method of fabricating a semiconductor device. According to the invention, the catechol-PEG derivative can be site-specifically conjugated with the N-terminal amine group of a protein or peptide, so that a homogeneous polyethylene glycol-protein or -peptide conjugate can be obtained in high yield. Upon the detection of one or more faults within the interconnect resources, the faulty interconnect resources are identified and a determination is made whether utilization of the faulty interconnect resources is compatible with an intended operation of the FPGAs. The data processing facility also includes a plurality of redundant data historians that are communicatively coupled to each other and to the cluster of redundant servers for storage of process data and analysis results. The invention features various orientations for mounting a pair of loudspeakers within an automobile which directly radiate sound out of a rear opening of the automobile.
