Claim:
1. A method of forming a microreactor, comprising: forming an elongated microfluidic first chamber within a body, the first chamber having a top and a bottom and first and second sides formed in the body, the first sides extending along a length of the first chamber between a first end and a second end of the first chamber and the second sides extending along a width of the first chamber, the length being greater than the width; forming a second chamber in the body; forming interconnections in the body, the interconnections fluidly coupling the first chamber and the second chamber, the interconnections having interconnection inlets on the bottom at a second end of the first chamber, the second end of the first chamber being nearer than the first end to the second chamber; forming a fluid inlet in the body fluidly coupled to the first chamber, the fluid inlet being on the top at the first end of the first chamber; and forming a vent passage in the body and having a vent outlet in the second chamber and at least one vent inlet on the bottom of the first chamber, at a location between the fluid inlet and the interconnection inlets along the length of the first chamber, wherein: forming the first chamber includes forming the first chamber in a first semiconductor substrate; and forming the vent passage includes forming a microfluidic channel in a second semiconductor substrate, wherein; forming the first chamber includes forming the first chamber with a hydraulic equivalent diameter; and forming the vent inlet includes forming the vent inlet in the first chamber at a distance of about one hydraulic equivalent diameter from the second end of the first chamber.
