摘要： Systems and methods are provided for mechanically cleaving a bonded wafer pair by controlling the rate of cleaving. This controlled rate of cleaving results in a reduction or elimination of non-uniform thickness variations in the cleaved surface of the resulting SOI wafer. One embodiment uses flexible chucks attached to the faces of the wafers and actuators attached to the flexible chucks to cleave the bonded wafer pair. Other embodiments also use rollers in contact with the surfaces to control the rate of cleaving.

摘要： This invention generally relates to a process for making a multi-layered crystalline structure. The process includes implanting ions into a donor structure, bonding the implanted donor structure to a second structure to form a bonded structure, cleaving the bonded structure, and removing any residual portion of the donor structure from the finished multi-layered crystalline structure.

摘要： Methods of slicing ingots of semiconductor material into wafers using a wire saw. The wire saw includes a wire that is movable in a forward direction and a reverse direction for slicing the ingots. The methods include defining an identification region of each wafer to be sliced from the ingots and aligning an alignment feature of the ingots in approximately the same position relative to the wire saw for each of the ingots. The identification region of the wafer is adapted for marking with an identification mark after slicing. The methods also include slicing the ingot into wafers with the wire saw. The slicing step includes moving the wire in the forward and reverse directions during slicing except when slicing in the identification region of each wafer and moving the wire only in the forward direction when slicing in the identification region of each wafer. In slicing the ingot into wafers, thickness variations relative to the size of the identification mark are reduced in the identification region.
摘要翻译：使用线锯将半导体材料锭切成晶片的方法。线锯包括可沿向前方向和相反方向移动的线，用于切割锭。这些方法包括定义要从锭切片的每个晶片的识别区域，并且将每个晶锭相对于线锯大致相同位置的锭的对准特征对准。晶片的识别区域适于在切片之后用识别标记进行标记。这些方法还包括用锭锯将锭切成晶片。切片步骤包括在切片期间沿着正向和反向的方向移动导线，除了当在每个晶片的识别区域中切片时，在每个晶片的识别区域中切片并且仅在每个晶片的识别区域中切片时在正向移动线。在将晶片切成晶片时，在识别区域中减小了相对于识别标记尺寸的厚度变化。

摘要： Methods and systems are disclosed for performing a passivation process on a silicon-on-insulator wafer in a chamber in which the wafer is cleaved. A bonded wafer pair is cleaved within the chamber to form the silicon-on-insulator (SOI) wafer. A cleaved surface of the SOI wafer is then passivated in-situ by exposing the cleaved surface to a passivating substance. This exposure to a passivating substance results in the formation of a thin layer of oxide on the cleaved surface. The silicon-on-insulator wafer is then removed from the chamber. In other embodiments, the silicon-on-insulator wafer is first transferred to an adjoining chamber where the wafer is then passivated. The wafer is transferred to the adjoining chamber without exposing the wafer to the atmosphere outside the chambers.

摘要： A method of producing rectangular seed bricks for use in semiconductor or solar manufacturing is disclosed. The method includes connecting an alignment layer to a top surface of a template, drawing alignment lines on the alignment layer to demarcate a plurality of nodes, connecting cylindrical rods to the alignment layer such that a center of each rod is aligned with a corresponding node, and slicing through the rods and the alignment layer with a wire web to produce rectangular seed bricks.
