Abstract

"DISPOSITIVO DE EJEçãO DE MICROFLUIDO QUE TEM CIRCUITOS LóGICOS E ACIONADORES EFICIENTES". A presente invenção refere-se a um substrato semicondutor para um cabeçote de ejeção de microfluido. O substrato inclui uma pluralidade de atuadores de ejeção de fluido colocados no substrato. Uma pluralidade de transistores acionadores é colocada no substrato para acionar a pluralidade de atuadores de ejeção de fluido. Cada um dos transistores acionadores tem uma área ativa que varia de cerca de 1000 até menos do que cerca de 15.000 <109>m¬ 2¬. Uma pluralidade de circuitos lógicos que incluem no mínimo um transistor lógico é acoplado aos transistores acionadores. Os transistores acionadores e lógicos são fornecidos por meio de um sistema de alta densidade de transistores MOS no qual, no mínimo, os transistores lógicos têm um comprimento de porta de cerca de 0,1 a menos do que cerca de 3 mícrons.
