Latest Patents
One of Cheevers' latest patents is a fluidic ejection device with layers having different light sensitivities. This invention describes a method for forming a fluidic ejection device that includes depositing a first layer on a silicon wafer, which consists of a first photoresist. The method involves exposing a portion of the first photoresist at a first energy level. Following this, a second layer is deposited on the first layer, which includes a second photoresist that is more sensitive to light than the first. The second energy level used for exposure is less than the first energy level. The process concludes with the development of unexposed portions of both photoresists to create an enclosed firing chamber and a nozzle.
Another significant patent involves interconnects through dielectric vias. In this invention, a dielectric layer includes a reflow via, which is formed by the reflow of the dielectric layer away from a raised feature. An interconnect is then established in contact with the raised feature through the reflow via.
