    • Apparatus for automatic scribing and breaking of semiconductor wafers wherein scribing is performed at a scribing station (S) and the scribed wafer transported in the X direction to a breaking station (B) on an X-Y table (3, 9). Scribing and breaking of parallel lines is accomplished by transporting the wafer step-wise in the Y direction by the Y table (3). Rotation of the wafer for scribing and breaking along sets of lines perpendicular to one another is accomplished by a theta table (18) carried on the Y table (3). An impulse bar (28) is carried by the X table (9) for applying force to the bottom surface of the wafer during both scribing and breaking. Scribing and breaking parameters needed to scribe and break the wafer are entered into computer memory and operated upon by computer controls to automate the scribing and/or breaking process.
    • 用于自动刻划和断裂半导体晶片的装置,其中在划线台(S)上进行刻划,并且将在X方向上传送的划片片移动到X-Y台(3,9)上的断裂台(B)。 平行线的划线和断裂是通过Y平台(3)沿Y方向逐步输送晶片来实现的。 通过在Y台(3)上承载的θ台(18)来实现用于划线和沿着彼此垂直的线组断开的晶片的旋转。 冲压棒(28)由X台(9)承载,用于在划线和断开期间将力施加到晶片的底表面。 将划片和断开晶片所需的刻划和断开参数输入到计算机存储器中,并通过计算机控制进行操作,以使划线和/或断开过程自动化。
