摘要： A pyroelectric element includes a pyroelectric substrate; a light-receiving section composed of a front-side electrode, a back-side electrode, and a light-receiving portion; and a light-receiving section composed of a front-side electrode, a back-side electrode, and a light-receiving portion. Since the pyroelectric substrate warps in a cavity-facing region opposite a cavity, the light-receiving area of the light-receiving sections is greater than that in the case where there is no warp. It is thus possible to improve detection sensitivity of the pyroelectric element without making the size of the pyroelectric element larger than that in the case where there is no warp.

摘要： A metal film is formed on at least a surface of a second substrate composed of ceramic (step c), and a first substrate composed of a group nitride is bonded to the second substrate through the metal film (step d). Since the metal film generally has higher thermal conductivity than oxide films, a composite substrate having high heat dissipation can be produced as compared with a case where the first substrate is bonded to the second substrate through an oxide film. In addition, a step of out diffusion is not required because of nonuse of an oxide film, thereby simplifying the process.
摘要翻译：在由陶瓷（步骤c）构成的第二基板的至少一个表面上形成金属膜，通过金属膜将由氮化物构成的第一基板接合到第二基板（步骤d）。由于金属膜通常具有比氧化膜更高的热导率，所以与第一衬底通过氧化膜结合到第二衬底的情况相比，可以制造具有高散热性的复合衬底。此外，由于不使用氧化膜，不需要扩散步骤，从而简化了工艺。
