This semiconductor device comprises a semiconductor chip, a signal lead connected to a signal electrode of the semiconductor chip, an external signal electrode connected with the signal lead, a ground lead extending along the signal lead, and a sealing resin sealing these elements. The external signal electrode is formed as a protruding electrode protruding from an undersurface of the sealing resin. One surface of the signal lead is exposed on the undersurface of the sealing resin.

Disclosed is a method to determine a needle mark, which can more accurately determine whether marks formed on electrode pads of devices are probe needle marks, thereby significantly reducing misdetermination of the marks as the probe needle marks. The method includes giving scores, which are used to determine the quality of marks as probe needle marks, to marks formed on a plurality of electrode pads of a plurality of devices, and selecting, based on the scores, an object device including an object electrode pad with an indefinite mark formed thereon, and selecting four comparison devices preceding the object device and nine time-successive comparison devices following the object device at successive times along the test direction, and determining if the indefinite mark of the object device is good or bad as a probe needle mark, by comparing a value of the score given to the indefinite mark of the object device plus scores given to marks formed on the comparison devices' comparison electrode pads corresponding to the object electrode pad, with a reference value.

A probe cleaning apparatus includes a cleaning-conditions database. The probe cleaning apparatus removes contamination from a probe by irradiating the probe by a laser beam, refers to the cleaning-conditions database based on information about the probe, such as material and shape, and controls properties of the laser beam, such as output intensity, pulse interval, wavelength, and pulse width, so that the probe cleaning apparatus removes the contamination from the probe without damaging the probe by heat.

A method of testing semiconductor devices includes an adhering step, a position correcting step, and an electrical test step. The adhering step includes adhering either a semiconductor device collective body or a plurality of individual semiconductor devices onto an adhesive tape provided on a tape-holding member, the semiconductor device collective body being constructed by a plurality of semiconductor devices integrated together. The position correcting step includes positioning the semiconductor devices by mounting the tape-holding member on a position correction unit and, using an image processing technique, implementing position recognition and position correction of the semiconductor devices adhered on the adhesive tape. The electrical test step includes implementing an electrical characteristic test on the semiconductor devices positioned in the position correction step by connected the semiconductor devices on a testing contactor.
