Apparatus and methods are described for aligning diagnostic and therapeutic iris images, via iris pattern recognition, for effecting more accurate laser treatment of the eye. The semiconductor device includes a LDMOS, a source plug electrically coupled to a source region of the LDMOS, a source wiring disposed over the source plug, a drain plug electrically coupled to a drain region of the LDMOS, and a drain wiring disposed over the drain plug. The loudspeaker is accommodated in the shell, dividing an inner space of the shell into a first resonance chamber and a second resonance chamber. on a conveyor belt, to produce reflected radiation and distinctive spectral features are measured indicative of the degree of degradation or oxidation of the oil sand ore. The latch member is provided with a pressed portion, and when the operation member is moved downward in a state that the latch member is engaged with the socket body, an engagement releasing member formed to the operation member presses the pressed portion to rotate the latch member so as to release the engagement of the latch member with the socket body. Provided is a semiconductor device that can reduce collapse of a pattern shape even if a shock is applied to the pattern formed with the phase transition material that is liquefied when the environmental temperature is not sufficiently controlled.
