    • A two-axis geomagnetic sensor is disclosed. The two-axis geomagnetic sensor includes a first geomagnetic sensor part including a first wafer and a first geomagnetic sensor on a surface of the first wafer; and a second geomagnetic sensor part including a second wafer and a second geomagnetic sensor on a surface of the second wafer. The first and second geomagnetic sensor parts are bonded to each other, in which the first and second geomagnetic sensors positioned in an orthogonal relation to each other. Accordingly, an occupancy area of the geomagnetic sensor can be reduced. Further, the geomagnetic sensor on each axe can have the same magnetic material properties, and alignment deviation cannot be generated.
    • 公开了一种双轴地磁传感器。 双轴地磁传感器包括第一地磁传感器部分,其包括在第一晶片的表面上的第一晶片和第一地磁传感器; 以及第二地磁传感器部分,其包括在第二晶片的表面上的第二晶片和第二地磁传感器。 第一和第二地磁传感器部分彼此结合,其中第一和第二地磁传感器以彼此正交的关系定位。 因此,可以减少地磁传感器的占用面积。 此外,每个斧头上的地磁传感器可以具有相同的磁性材料性质,并且不能产生对准偏差。

    • A method of fabricating inkjet print heads usable in an ink jet printer. The method of fabricating ink jet print heads includes preparing a plurality of ink jet print heads on a wafer while forming sub sidewalls around the ink jet print heads when the ink jet print heads are being prepared, attaching protection films onto the sub sidewalls of the wafer and the ink jet print heads, and dicing the ink jet print heads and detaching the individual ink jet print heads from the wafer. In the method, the ink jet print heads are diced in a wafer unit. Particularly, connect pads of the ink jet print heads can be prevented from being contaminated by the protection films.
    • 一种制造可用于喷墨打印机的喷墨打印头的方法。 制造喷墨打印头的方法包括:当准备喷墨打印头时,在晶片上准备多个喷墨打印头,同时在喷墨打印头周围形成副侧壁,将保护膜附着在晶片的子侧壁上 和喷墨打印头,并且对喷墨打印头进行切割并将各个喷墨打印头从晶片上分离出来。 在该方法中,喷墨打印头在晶片单元中切割。 特别地,可以防止喷墨打印头的连接垫被保护膜污染。
