A method for adhesive stacking includes dispensing a first line of adhesive onto a first substrate; dispensing at least one additional line of adhesive stacked onto the first line of adhesive; and placing a second substrate onto the at least one additional line of adhesive to join the first and second substrates.

Stacked adhesive lines

In an embodiment, a fluid ejection device includes a die including a fluid feed slot that extends from a back side to a front side of the die, a firing chamber formed on the front side to receive fluid from the feed slot, a fluid distribution manifold adhered to the back side to provide fluid to the feed slot, and a corrosion-resistant layer coating the back side of the die so as not to extend into the feed slot.

Fluid ejection device and methods of fabrication

A micro electro-mechanical system (MEMS) device includes an electrical wafer, a mechanical wafer, a plasma treated oxide seal bonding the electrical wafer to the mechanical wafer, and an electrical interconnect between the electrical wafer and the mechanical wafer.

Micro electro-mechanical system packaging and interconnect

A packaged micro-electromechanical systems (MEMS) device assembly includes a MEMS device, a substrate within which the MEMS device is disposed, and a lid disposed over the substrate. The assembly may include one or more first cavities within the lid having a predetermined volume satisfying packaging specifications for the packaged MEMS device assembly. The assembly may include one or more second cavities within the lid and one or more corresponding overflow areas within the lid, where each second cavity contains a material and each corresponding overflow area is adapted to catch overflow of the material. The assembly may include one or more third cavities within the lid and one or more channels within one of the substrate and the lid to fluidically connect the MEMS device to the third cavities.

Packaged MEMS device assembly

In one embodiment, a package for a micro-device includes a substrate, a transparent material covering the substrate, and a bond ring bonding the transparent material to the substrate. The bond ring comprises a silicon oxide layer on one of the substrate or the transparent material bonded to a silicon layer on the other of the substrate or the transparent material.
