This invention relates to a TFT-LCD and a manufacturing method therefor which etches triple layer patterns in a single process step. The lamps are electrically interconnected via standard wiring and adhesively affixed along the bed frame. Between the TFT substrate and the counter substrate, a columnar spacer is disposed in a center portion of a pixel region so as to at least partially overlap with the storage capacitor counter electrode. The interfaces may comprise a backplane PHY, for example, a 10 GBASE-KR, a 10 GBASE-KX4 andor a 1 GBASE-KX PHY which may perform FEC. A die attach machine may include a control system for automatically implementing such method. A probability calculator calculates a probability indicating a degree of coincidence among the target voice signal and a plurality of words in sample data.
