MICROFLUIDIC CHANNELS SEALED WITH DIRECTIONALLY-GROWN PLUGS - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240014101 titled 'MICROFLUIDIC CHANNELS SEALED WITH DIRECTIONALLY-GROWN PLUGS

Simplified Explanation

The abstract describes a patent application for structures and methods of forming a microfluidic channel. The structure includes a trench in a semiconductor substrate and a semiconductor layer inside the trench. The trench has an entrance and a sidewall extending into the substrate, while the semiconductor layer has a first portion surrounding a portion of the trench to define a cavity and a second portion positioned to obstruct the entrance to the trench. The second portion of the semiconductor layer is thicker than the first portion.

  • The patent application is for a structure and method of forming a microfluidic channel.
  • The structure includes a trench in a semiconductor substrate and a semiconductor layer inside the trench.
