A semiconductor wafer dicing process is disclosed for dicing a wafer into individual dies. Scribe lines are formed within a polymer coating to expose regions of wafer to form a pre-processed product. The pre-processed product within the chamber is plasma etched to remove the exposed regions of the wafer to separate the individual dies and form a processed product. A frame cover is then removed and the processed product, wafer frame and adhesive tape are exposed to an oxygen plasma within the chamber to partially remove an outermost region of the polymer coating, which is most heavily contaminated with fluorine, to leave a residual polymer coating on the individual dies and form a post-processed product. The residual polymer coating on the individual dies of the post-processed product is then removed.

A workpiece unit that includes a workpiece, a tape stuck to the workpiece; and an annular frame to which an outer circumferential edge of the tape is stuck and which has an opening defined centrally therein. The workpiece is disposed in the opening in the annular frame and supported on the annular frame by the tape, and at least one of the tape and the annular frame has an irreversible discoloring section that discolors in response to an external stimulus. Such a configuration makes it possible to determine whether or not a process involving an external stimulus has been carried out on the workpiece unit, based on the appearance of the workpiece unit (i.e., based on whether the irreversible discoloring section has been discolored or not).

A substrate positioning apparatus includes a holder and a rotating device. The holder is configured to hold a substrate. The rotating device is configured to rotate the holder. The rotating device includes a rotation shaft, a bearing member, a base member, a driving unit and a damping device. The rotation shaft is fixed to the holder.

The apparatus including a heater and a substrate holder with a substrate holder surface, wherein the substrate to be heated can be placed on the substrate holder surface, the apparatus further includes means for exerting forces on the heater, the apparatus further includes a control unit for controlling the means, wherein the heater is deformable by the means.

A bonding system includes a bonding device, an inspection device and a controller. The bonding device forms a combined substrate by bonding a first substrate and a second substrate to each other. The inspection device inspects the combined substrate. The controller controls the inspection device. The controller includes a measurement controller, a comparison unit and a re-measurement controller. The measurement controller causes the inspection device to measure the combined substrate at a first number of measurement points. The comparison unit compares, with a reference, an inspection result including a deviation amount between the first substrate and the second substrate in the combined substrate based on a measurement result. The re-measurement controller causes the inspection device to re-measure the combined substrate at a second number of measurement points greater than the first number of measurement points based on a comparison result obtained by the comparison unit.

A wafer processing apparatus includes a pressure applying element, a rotatable element, a control element, and a heat source. The pressure applying element includes a first pressure applying head having a first working surface and a second pressure applying head having a second working surface. The rotatable element and the pressure applying element are connected. The control element is electrically connected to the rotatable element. The heat source is disposed beside the pressure applying element.

A method for producing an edge structure of a semiconductor component includes: providing a semiconductor body having at least two mutually spaced-apart main faces respectively having an edge, between which edges an edge face extends; and etching a predetermined edge contour by purposely applying a chemical etchant onto the edge face by an etchant jet with simultaneous rotation of the semiconductor body about a rotation axis. The etchant jet is guided with a predetermined jet cross section, while being directed tangentially with respect to the edge face, such that the etchant jet impinges on the edge face only with a part of the jet cross section. A corresponding device for producing an edge structure of a semiconductor component is also described.

Cleave systems for cleaving a semiconductor structure are disclosed. The cleave systems may include a cleave arm that is moveable from a starting position to a raised position in which a cleave stress is applied to the semiconductor structure. Spring members store energy as the cleave arm is raised with the stored spring energy causing the structure to cleave into two pieces upon initiation of the cleave across the structure.

A processing method of a workpiece used when the workpiece is processed is provided. The processing method of a workpiece includes a disposing step of disposing the workpiece in a gas containing a substance that generates an active species that reacts with the workpiece, a measurement step of measuring the distribution of the thickness of the workpiece disposed in the gas, and a laser beam irradiation step of irradiating the workpiece in the gas with a laser beam of which the power is adjusted based on the distribution of the thickness measured in the measurement step. In the laser beam irradiation step, the removal amount by which a region irradiated with the laser beam in the workpiece is removed by the active species is controlled by irradiating the workpiece with the laser beam of which the power is adjusted.
