An oscillator includes a resonant circuit of at least one inductance device and at least one tunable capacitance. The device includes a handset interface, a first converter, an encryption processor, a second converter, and a host interface. Thus, a MOS transistor having a structure in which the surfaces of the source region and the drain region are elevated over the surface of the silicon substrate is formed. The paused flow sends a request for permission to resume execution to a sync servlet. The first area of the first mask layer covers sidewalls of adjacent mold mask patterns from among the plurality of mold mask patterns by being located between the adjacent mold mask patterns, and the second area of the first mask layer covers portions of the sidewalls of the plurality of mold mask patterns, the portions corresponding to an outermost sidewall of a mold mask pattern block. According to the invention, only the reflecting surface intended to form an illuminating or indicating beam is metallised or metallic, and the mask is made of transparent material.
