Title:
【発明の名称】インクジェットヘッド及び該ヘッド用基体の製造方法
Document Type and Number:
Japanese Patent JP2971473
Kind Code:
B2
Abstract:
A process for preparing an ink jet head having a support (1), an electrothermal transducer provided on the support and having a heat-generating resistor (8) and a pair of electrodes (3) electrically connected to the heat-generating resistor (8), a first upper layer (4-1) provided. on the electrothermal transducer, a second upper layer (4-2) provided on the first upper layer and a liquid path (6) communicated with a discharge opening (7) for discharging liquid and formed on the support so as to correspond to the heat-generating portion of the electrothermal transducer formed between the pair of electrodes (3) comprises the steps of: forming the first upper layer (4-1) by the bias sputtering method at the absolute value of the bias voltage of 50V or less and forming the second upper layer (4-2) by the bias sputtering method at the absolute value of the bias voltage higher than 50V.
