An optoelectronic device may include an insulating substrate, a semiconductor channel region located on the insulating substrate, and a source region and a drain region in contact with the semiconductor channel region. Other forms of the invention encompass other processes, improved packets and packet ensembles, integrated circuits, chipsets, computer cards, information storage articles, systems, computers, gateways, routers, cellular telephone handsets, wireless base stations, appliances, and packet networks, and other forms as disclosed and claimed. The SOM can be provided as a form of a monomer having an aromatic ring with various polarity, flexible side chain and hydrophilic dibasic acid, as a form of a complex consisting of the monomers linked by a hydrogen bond or a metal coordinate bond or as a form of a whole aromatic polymer having NRCO, NROSO nSO3H, nCO2H or -tert-butyloxycarbonyl) and OCO. A bypass connects one of the electric paths connected to one of both ends of the conductive member; and the other of the pair connected to the other of the both ends. If the testing pole is capable of being inserted into the test hole, the coaxial accuracy between the test and standard holes of the object is qualified.
