Abstract:
PURPOSE: An infrared detector is provided to increase the temperature of an absorbing body effectively by the generation of heat caused by absorbing infrared rays. CONSTITUTION: An infrared detector(10) comprises a substrate(11), a resonator(30), a thermoelectric material layer(50), a lead line(60), a thermal isolation layer(70), and a ground plate layer(90). The resonator absorbs infrared rays becoming incident. The thermoelectric material layer is in contact to the resonator, and a resistance value of the thermoelectric material layer is varied according to a temperature change caused by the absorbed infrared rays. The lead line electrically connects the thermoelectric material layer and the substrate. The thermal isolation layer is arranged between the substrate and the thermoelectric material layer, thereby preventing thermal transmission to the substrate. The ground plate layer prevents the infrared rays toward the substrate.

Abstract:
A resonator, an apparatus having the same, and a method for manufacturing the resonator are provided to improve a roll off characteristic of an electronic component by freely adjusting an effective piezoelectric thin film coefficient in a wide range. A resonator includes a substrate(110), a resonating unit(135), and first and second electrode layers(141,142). The resonating unit includes a lower electrode, a piezoelectric film, and an upper electrode which are sequentially laminated on the substrate. The first and second electrode layers are made of the same material with differential crystalline properties, so that a resonance piezoelectric thin film coefficient is adjusted. One of grain sizes or surface roughness properties is different in the first and second electrode layers.

PURPOSE: A method for manufacturing a metal structure using a trench is provided to be capable of simplifying the manufacturing process and easily carrying out a post process. CONSTITUTION: A plurality of trenches are formed in a substrate(100). A seed layer(102) is deposited along the upper surface of the resultant structure. An insulating layer(103) is deposited on the seed layer. The insulating layer on the trenches is partially removed to expose the seed layer. The trenches are then filled with a metal layer(104). The insulating layer and the seed layer are removed from the resultant structure. Preferably, the insulating layer formed at the bottom of the trench is removed for obtaining a metal structure.
