Abstract
Description
Technical Field
[0001] The utility model mainly relates to a process technology used in a production process, and specifically relates to a fixture for adjusting the crystal orientation of a crystal rod. Background Art
[0002] There is a slicing process in the semiconductor wafer manufacturing process, which is used to cut the crystal rod into chips for subsequent processing. Before cutting the crystal rod, it is necessary to measure and confirm the crystal orientation of the crystal rod. If there is a problem with the crystal orientation of the crystal rod, the crystal orientation of the chip after cutting will not meet the production requirements, causing all the chips to be scrapped, resulting in great losses. At present, the industry adjusts the crystal orientation by placing iron blocks on both sides of the resin strip on the steel plate after the crystal rod is bonded. The crystal orientation is adjusted on the optical ruler by pushing the iron blocks so that the crystal orientation of the crystal rod meets the production requirements. In the current process, if the number of crystal rods bonded is small, the number of iron blocks required will not be greatly affected. However, after the number of bonding increases, the number of iron blocks required will increase, resulting in increased costs and inconvenience in collection and management. This fixture adopts an integrated design solution. After placing the crystal rod on the optical ruler, the fixture is put on the steel plate to adjust the crystal orientation, and then removed after adjustment. One fixture can complete the adjustment, reducing costs and facilitating collection and management. Utility Model Content
[0003] In order to improve the above situation, the purpose of the utility model is to provide a fixture for adjusting the crystal orientation of a crystal rod.
[0004] The purpose of the utility model can be achieved through the following technical solutions: the jig is composed of a left fixing groove, a right fixing groove, a front fixing groove and a socket, and is used in the crystal orientation adjustment process of the crystal rod. The jig is installed on a steel plate for adjustment, which can meet the operating requirements of resin strips of different lengths, reduce costs, and facilitate collection and management.
[0005] In one embodiment of the utility model, the fixture can be adjusted in a certain proportion according to the specifications of the steel plate and the resin strip.
[0006] In one embodiment of the utility model, the left fixing groove, the right fixing groove and the front fixing groove of the fixture correspond to the size of the steel plate and are complementary in shape, thereby playing a fixing and limiting role.
[0007] In one embodiment of the present invention, there are insertion holes on the left fixing groove and the right fixing groove of the fixture for placing a device for adjusting the crystal orientation of the crystal rod.
[0008] In one embodiment of the present invention, the front fixing groove of the fixture is used to connect the left and right fixing grooves, while ensuring that the fixture will not loosen or fall off, thereby playing the role of connection and fixed limit.
[0009] Based on the above, the advantages and characteristics of the embodiment of the utility model are that the fixture adopts an integrated design scheme, has a simple structure, is easy to install and remove, is easy to switch specifications, can reduce costs, and is easy to collect and manage. The fixture can be applied to the crystal rod crystal orientation adjustment process, can meet the operating requirements of resin strips of different specifications, and is easy to install and remove, which can reduce production costs.
