摘要： ST-cut and AT-cut quartz seed bodies (18,40) for quartz crystal synthesis and method (100) for making the same are disclosed. An extended quartz seed body (18) having an angle of about 42.75.degree. rotated about a X axis (20) from a +Z axis (22) to a -Y axis (24) and defining a ST-cut is provided and a quartz crystal bar (32) is grown thereupon. Analogously, an extended quartz seed body (40) having an angle of about 35.25.degree. rotated about a X axis (20) from a +Z axis (22) to a -Y axis (24) and defining an AT-cut is provided and a quartz crystal bar (48) is grown thereupon. In each case, the subsequent quartz crystal bar (32,48) may be wafered parallel to the seed body (18,40) thereby; reducing waste (68), recovering the seed body (18,40) for reuse, producing wafers (70) without intervening seed portions, and increasing factory capacity.
