热隔离微机电系统（MEMS）器件的单片制造
摘要：
本发明涉及热隔离微机电系统（MEMS）器件的单片制造。提供了一种用于制造热隔离微机电系统（MEMS）结构的方法。所述方法包括用玻璃晶片来处理第一材料的第一晶片以形成复合衬底，该复合衬底包括玻璃和第一材料的至少一个牺牲结构；在第二材料中形成MEMS器件；在以下各项中的至少一个上形成至少一个温度感测元件：复合衬底；以及MEMS器件；以及蚀刻掉复合衬底中的第一材料的所述至少一个牺牲结构以形成至少一个热隔离玻璃弯曲部分。在热隔离台阶上通过所述至少一个热隔离玻璃弯曲部分将MEMS器件热隔离。所述至少一个温度感测元件在以下各项中的相应至少一个上：热隔离台阶；以及MEMS器件。
摘要（英）：

The invention relates to monolithic fabrication of thermally isolated microelectromechanical system (MEMS) devices. A method for fabricating a thermally isolated microelectromechanical system (MEMS) structure is provided. The method includes processing a first wafer of a first material with a glass wafer to form a composite substrate including at least one sacrificial structure of the first material and glass; forming a MEMS device in a second material; forming at least one temperature sensing element on at least one of: the composite substrate; and the MEMS device; and etching away the at least one sacrificial structure of the first material in the composite substrate to form at least one thermally isolating glass flexure. The MEMS device is thermally isolated on a thermal isolation stage by the at least one thermally isolating glass flexure. The at least one temperature sensing element in on a respective at least one of: the thermal isolation stage; and the MEMS device.
