Ink-jet type recording head and monolithic integrated circuit suitable therfor |
摘要 |
A recording head comprises a liquid emission member having an orifice through which an ink is emitted, an electro-thermal converter element for generating a thermal energy which is utilized to emit the ink introduced into the liquid emission member, and a functional element disposed on a same substrate on which the electro-thermal converter element is disposed for driving and controlling the electro-thermal converter element. The functional element includes an NPN bipolar transistor for driving the electrothermal converter element and a CMOS transistor composed of an NMOS transistor and a PMOS transisfor for controlling an operation of the bipolar transistor. The NMOS transistor being formed in a P well diffusion layer in an N- type epitaxial growth layer which is grown on a surface of a P type semiconductor substrate. The PMOS transistor being formed in an N well diffusion layer in the N- type epitaxial growth layer which is grown on the surface of the P type semiconductor substrate.
