摘要： A method of making ink jet printer head body provides a silicon wafer forming a restrictor plate over the silicon wafer by doping an impurity component. A nozzle plate is formed under the silicon wafer by doping an impurity component and a nozzle is formed by etching after the forming of the nozzle plate. A channel going through the restrictor plate and silicon wafer is formed by etching after the forming of the restrictor plate. The channel is formed of a wide upper portion and a narrow lower portion by patterning the silicon wafer and restrictor plate narrowly and etching the silicon wafer and restrictor plate, and then patterning the silicon wafer and restrictor plate widely and etching the silicon wafer and restrictor plate, except for the lower end of the silicon wafer. A restrictor at the restrictor plate is formed by etching after the patternings of the restrictor plate. One or more reservers continue to the restrictor under the restrictor by etching a definite thickness after the patternings of the silicon wafer.

摘要： Disclosed is a method for fabricating a piezoelectric/electrostrictive thick film, using a seeding layer. On a substrate is formed the seeding layer which is prepared from a ceramic sol solution or a ceramic paste, both identical or similar in composition to the piezoelectric/electrostrictive film. The ceramic paste is prepared from a mixture of a ceramic oxide powder, which has a particle size of 5 &mgr;m or less and is prepared from Pb and Ti-based piezoelectric/electrostrictive elements by a non-explosive oxidation-reduction combustion reaction at 100-500° C., and a ceramic sol solution in water or an organic solvent, identical or similar in composition to the ceramic oxide powder. Then, the seeding layer is subjected to an after-treatment. A piezoelectric/electrostrictive film is directly formed on the seeding layer. Alternatively, a piezoelectric/electrostrictive film, separately formed and sintered, is attached on the seeding layer.

摘要： Disclosed is a method for fabricating a piezoelectric/electrostrictive thick film, using photolithography. On a vibrating plate is formed a bottom electrode. Over the bottom electrode, a photoresist is coated, exposed to light and developed to form molds in fine patterns. Separately, a ceramic paste is prepared by mixing a ceramic oxide powder and a ceramic sol solution. The ceramic oxide powder has a particle size of 5 &mgr;m or less and is prepared from Pb and Ti-based ceramic oxide powder by a non-explosive oxidation-reduction combustion reaction at 100-500° C. while the ceramic sol solution, identical or similar in composition to the ceramic oxide powder, uses water or an organic solvent as an base. Next, the ceramic paste is filled in the molds to form a piezoelectric/electrostrictive film, followed by conducting a thermal treatment at 100 to 300° C. to sinter the film. Finally, a top electrode is formed on the film. Alternatively, the bottom electrode may be not formed if the vibrating plate is of electroconductivity. In the micro actuator, a high aspect ratio of fine patterns and a significant improvement in the bonding properties between the film and the infrastructure are achieved. Also, the film is protected from external damage, such as scratching, because the molds surround the film.
