Title:
インクジェット印刷ヘッド
Document Type and Number:
Japanese Patent JP4749546
Kind Code:
B2
Abstract:
An ink jet printhead optimally utilizes the surface area of the upper face of a silicon die, even in the case of a non-monochromatic head having plural ink tanks. For each tank of ink, the ink includes one pass-through slot that departs from the lower face of the silicon die and terminates in a wider trench in the upper face. The pass-through slot is made using a chemical etching type incision technique known as "inductively coupled plasma" (ICP), thus maximizing the distance between the different ink tanks and, simultaneously, minimizing the distance between the different groups of nozzles on the upper face of the die. Accordingly, the risk of the silicon substrate breaking during any of the various stages of manufacture is considerably reduced.
