Embodiment Construction

[0021] figure 1 This figure is drawn to describe the cross-sectional structure of one point of heater board IC 20 , a heater device for an inkjet print head formed in one embodiment of the present invention. The heater board IC 20 is an IC (integrated circuit) used for a print head such as a thermal (heating) inkjet printer.

[0022] The heater board IC 20 has a base layer 22 disposed on a semiconductor substrate, and a wiring layer 26 disposed in contact therewith so as to partially cover the base layer 22 . The base layer 22 is made of an insulating material—silicon oxide (SiO 2 )constitute. The wiring material constituting the wiring layer 26 is not particularly limited, but in this embodiment, aluminum·copper (Al—Cn) is used as the wiring material.

[0023] A portion of the base layer 22 not covered by the wiring layer 26 is referred to as a "heater arrangement portion 22a". The heater layer 24 is arranged in contact with them, and covers the heater arrangement portio...

Abstract

This invention has disclosed a kind of complex type and gushed out the black head printer, through setting up the compounding type to gush out the black head module in the printer, its compounding type gushes out the black head module and contains gushing out the black head of two or more, and drip the same color of offering different size blackly separately, among it is so can at one time reciprocating motion with when offer there aren't size China ink more than of two kinds, and then reduce the number of times of typing reciprocating motion , namely promote it and type the speed and maintain the photograph to type quality.

Description

technical field [0001] The invention relates to a heater device for an inkjet print head and a manufacturing method thereof, in particular to a heater device for a thermal inkjet print head. Background technique [0002] A heater board IC (Integrated Circuit) used in a heater device for a thermal inkjet print head has long been known. (For example, refer to Japanese Patent Application Laid-Open No. 2002-339085). Figure 6 is a figure drawn to describe the dot cross-sectional structure of such a conventional heater board IC. [0003] Heater board IC2, with silicon oxide (SiO 2 ) composed of base layer 4, heater layer 6 composed of tantalum silicon nitride (Ta SiN), wiring layer 8, plasma nitride film 10 composed of silicon nitride (SiN), and tantalum (Ta) Heater protective layer 12. A portion of the heater layer 6 not covered by the wiring layer 8 is a heater portion 14 . [0004] When printing is performed using the heater board IC 2 , printing ink is supplied onto the h...
