Title: Method of manufacturing electronic component
Inventor: TAKAHASHI KOICHI
IPC: H01L21/52
Filed: 2000-04-10
Abstract: PROBLEM TO BE SOLVED: To provide a method of manufacturing electronic component by which the occurrence of defective resin encapsulation can be prevented. SOLUTION: In this method of manufacturing electronic component constituted by mounting semiconductor chips on a substrate, a die bonding step for mounting the semiconductor chips on the substrate and bonding the chips to a plurality of mounting points of the substrate is performed prior to a resin encapsulation step. When a bad mark is detected from one mounting point as a result of recognizing the mounting points in the die bonding step, the mounting point is discriminated as a defective mounting point, and a defective chip which is discriminated as defective among the semiconductor chips is mounted on the mounting point.  In the resin encapsulation step, consequently, the injected quantity of the resin used for the encapsulation can be made uniform by eliminating the occurrence of mold cavities in a state where the chips are not mounted and the occurrence of the defective resin encapsulation can be prevented by preventing the occurrence of defective injections caused by the quantity fluctuation of the resin.

IPC: G10L21/02
Filed: 2000-04-27
Abstract: PROBLEM TO BE SOLVED: To normalize individual differences resulting from peculiarities of vocalization with a small amount of voice data. SOLUTION: In a learning mode, a matching and averaging processing part 6 finds a frequency warping function regarding spectrum envelopes of an object speaker and a standard speaker to find and stores a mean value for every 'phonemes', 'similar phonemes', 'voiced sound sections/voiceless sound sections', and 'the whole voice section'. In recognition mode, spectrum envelope conversion from the object speaker to be recognized to the standard speaker is performed by using the mean frequency warping function and the obtained speaker-normalized spectrum envelope is used to recognize phonemes. At this time, the frequency warping frequency is computed by using mean spectrum envelopes averaged for every phoneme, so individual differences resulting from peculiarities of vocalization can be normalized.  When the amount of voicing data of the object speaker is small, a mean frequency warping frequency of 'similar phonemes', 'voiced sound sections/voiceless sound sections', etc., is used.
