Bubble tolerant manifold design for a liquid ejecting head

A liquid ejecting head, comprising:

• a pressure generating chamber plate defining pressure generating chambers therein;
• a vibrating plate disposed above the pressure generating plate and defining a pressure generating element for generating pressure within the pressure generating chambers;
• a nozzle plate defining nozzles that communicate with respective pressure generating chambers, wherein the pressure generating element is configured to cause liquid to be ejected through the nozzles;
• a manifold plate disposed above the nozzle plate and defining a manifold that communicates with a liquid introduction opening and that serves as a common flow channel for the multiple pressure generating chambers;
• a communication chamber plate disposed below the pressure generating chamber plate and defining liquid supply channels;
• and
• a supply opening plate disposed between the manifold plate and the communication chamber plate and defining liquid supply openings that open into the manifold, that communicate between the manifold and the liquid supply channels;
• wherein at least one of the liquid supply openings is physically separated from at least one adjacent one of the liquid supply openings.

A method of manufacturing a liquid ejecting head, comprising:

• providing a pressure generating chamber plate, which defines pressure generating chambers therein;
• attaching a vibrating plate above the pressure generating plate, where the vibrating plate comprises a pressure generating element for generating pressure within the pressure generating chambers;
• providing a nozzle plate, which defines nozzles for communicating with respective pressure generating chambers, wherein the pressure generating element is configured to cause liquid to be ejected through the nozzles;
• attaching a manifold plate above the nozzle plate, where the manifold plate defines a manifold that communicates with a liquid introduction opening and that serves as a common flow channel for the multiple pressure generating chambers;
• attaching a communication chamber plate below the pressure generating chamber plate, where the communication chamber plate defines liquid supply channels;
• attaching a supply opening plate below the communication chamber plate, where the supply opening plate defines liquid supply openings configured to open into the manifold, for communicating between the manifold and the liquid supply channels;
• providing a depression plate substrate;
• forming at least one depression in the depression plate substrate to thereby form a depression plate;
• and
• attaching the depression plate between the manifold plate and the supply opening plate such that at least one of the liquid supply openings is disposed in the depression, such that the depression physically separates the liquid supply opening from at least one adjacent one of the liquid supply openings.
