A method of forming an opening through a substrate having a first side and a second side opposite the first side includes forming a trench in the first side of the substrate, forming a mask layer within the trench, forming at least one hole in the mask layer, filling the trench and the at least one hole, forming a first portion of the opening in the substrate from the second side of the substrate to the mask layer, and forming a second portion of the opening in the substrate from the second side of the substrate through the at least one hole in the mask layer to the first side of the substrate.

摘要:
An apparatus and a method for introducing a particulate matter along with a driving liquid, such as water, into a ground surface. The apparatus is also highly effective for perforating and thereby aerating the ground surface. The particulate matter may preferably adopt the form of a powder like substance often referred to as "polymer" and which is injected into the ground for purposes of acting as a plant food or a plant additive in various agricultural operations. The apparatus utilizes an injector device for mixing the polymer or other particulate matter with the driving liquid, such as water, at a point in close proximity to the ground surface so that there is no pre-mixing of the particulate matter and the driving liquid. The driving liquid is pumped to the injector at a high pressure and introduced into a high pressure chamber of the injector. The liquid is then forced through a very small diameter nipple opening leading to a low-pressure chamber. This will, in turn, cause a venturi effect in the low pressure chamber and which also causes a sucking or introduction of the particulate matter into the low pressure chamber where the particulate matter and the liquid are mixed and then injected directly into a ground surface. The particulate matter is contained within a collapsible bag such that the bag will collapse around the particulate matter as it is periodically withdrawn therefrom.

In one embodiment, a fluid ejector structure includes an orifice sub-structure and an ejector element sub-structure direct contact bonded together along a direct contact bonding interface. The orifice sub-structure has a plurality of orifices therein. Each orifice is positioned adjacent to a corresponding one of a plurality of fluid ejection elements on the ejector element sub-structure.

A method of forming a MEMS device includes depositing a conductive material on a substructure, forming a first sacrificial layer over the conductive material, including forming a substantially planar surface of the first sacrificial layer, and forming a first element over the substantially planar surface of the first sacrificial layer, including communicating the first element with the conductive material through the first sacrificial layer. In addition, the method includes forming a second sacrificial layer over the first element, including forming a substantially planar surface of the second sacrificial layer, forming a support through the second sacrificial layer to the first element after forming the second sacrificial layer, including, filling the support, and forming a second element over the support and the substantially planar surface of the second sacrificial layer. As such, the method further includes substantially removing the first sacrificial layer and the second sacrificial layer, thereby supporting the second element relative to the first element with the support.
