Abstract: A flow sensor is provided having a substrate with a sensing element and flow channel aligned over the sensing element. The sensing element senses at least one property of a fluid. The flow channel is aligned by one or more guide elements formed in an alignment layer. The flow channel across the sensing area is accurately and precisely aligned due to the guide elements provided at the wafer-level, facilitating reliable, low-cost, and consistent results among multiple flow sensors. The flow sensor is adapted for use in harsh environments.

Abstract: A robust sensor that incorporates the necessary physical structure and thermal characteristics is capable of measuring fluid flow and properties under harsh environmental conditions. The sensor die is made of a material with thermal conductivity tailored to provide the thermal transmission characteristics necessary to avoid saturation of the sensor, thus enabling the measurement of high mass flux airflow and liquid properties under high pressure and often harsh environments not previously available for silicon based sensors. The robust sensor further has internal vias for back-side electrical connection, thus avoiding electrical and mechanical interference with the measurements. All of these features come together to provide a microsensor which is capable of reliable, i.e. stable, wide dynamic range and rapid-response operation under harsh environments.
Abstract translation: 结合必要的物理结构和热特性的坚固的传感器能够在恶劣的环境条件下测量流体流动和性能。 传感器芯片由具有导热性的材料制成，以提供避免传感器饱和所必需的热传递特性，从而能够在高压和常常恶劣的环境下测量高质量通量气流和液体性能，以前不可用于硅 基于传感器。 坚固的传感器还具有用于背面电气连接的内部通孔，从而避免了电气和机械干扰测量。 所有这些特征汇集在一起，以提供能够在恶劣环境下可靠，即稳定，宽动态范围和快速响应操作的微型传感器。
