A semiconductor processing method includes forming a conductively doped plug of semiconductive material within a first insulative layer. The use of the symmetric pin allows automatic insertion of the pin in that the orientation of the pin relative to the board is unimportant. In one implementation, the ductile metallic members are generally rectangular and each has a pair of longitudinal ends. Thereby, near-field light effuses from the plasmon probe into a very small area and heats the magnetic bit of the magnetic disk. The indicator is configured to indicate a position of the down stop. The method further comprises connecting a signal wire at one end to the accelerometer and at an opposite end to a signal processor, and increasing the signal output’s signal-to-noise ratio.
