A process for effectively reducing reactivity of a surface of a semiconductor substrate is described. The process includes: (1) oxidizing in an oxidizing environment the semiconductor substrate surface, the semiconductor substrate having a dopant concentration profile that extends across a depth of the semiconductor substrate; and (2) annealing the semiconductor substrate surface in an inert gas environment, wherein the oxidizing and the annealing of the semiconductor substrate surface are performed at a temperature that is sufficiently low to substantially preserve the dopant concentration profile in the semiconductor substrate. A surface passivation apparatus is also described. The apparatus includes: a heating source for heating a substrate surface; an ozone generator; and a chamber for exposing a substrate surface to an oxidizing environment that includes a gas composition, wherein the ozone generator is configured to produce ozone within the chamber using the gas composition.

The scanning unit includes a scanning plate with a first and second scanning fields that are arranged offset from each other in a measuring direction (x) by a distance, D. A first deflection element associated with the first scanning field and a second deflection element associated with the second scanning field, wherein the first and second deflection elements spatially separate the phase-shifted partial signals from the first and second scanning fields. First and second detector elements are placed downstream of the scanning plate and associated with the first scanning field. Third and fourth detector elements are placed downstream of the scanning plate and associated with the second scanning field. The first and second scanning fields are arranged on the scanning plate so that the offset distance D=TP/2*(N+1/4), wherein N=0, 1, 2, . . .

摘要:
A position measuring apparatus includes an optical instrument placed in a first plane, a first diffraction grid placed in a second plane, parallel to the first plane, a retro-reflecting element, a second diffraction grid, and an optical element, preferably placed in the first plane. The optical instrument splits a beam of light into at least two divergent partial beams which are diffracted by the first diffraction grid into parallel partial beams. The parallel partial beams are conducted through the retro-reflecting element and then impinge onto the second diffraction grid. The second diffraction grid diffracts the partial beams and causes them to interfere with each other at the optical element. A detection device measures a change (.DELTA.OPD) of path difference of the partial beams which is directly proportional to the change in distance between the first and second planes. This change (.DELTA.OPD) of the path difference can be detected by the detection device as a light-dark modulation at the optical element.
摘要:
The concentration of internal gettering sites within a semiconductor wafer is controlled by two-step thermal processing. In a concentration reduction phase, the wafer is rapidly heated to an elevated temperature in the range from about 900.degree. to 1350.degree. C., resulting in the partial or total dissolution of precipitable impurities within the wafer. In a concentration enhancement step, the wafers are subjected to a relatively low temperature anneal process where the density of potential internal gettering sites is increased. By properly controlling the processing temperatures and treatment times, the two steps may be performed in either order to obtain wafers having internal gettering site concentrations within a desired range.
摘要:
A mixing apparatus utilizes piston burettes driven by stepping motors as metering pumps to deliver component liquids to be mixed into a liquid stream in a selectable constant mixing ratio. A computer-based automatic control system is used to control the regulated take up of the respective components by the burettes and the delivery of them to a mixing device. The computer calculates the rates of stepping of the respective motors so that each component is delivered over the same period of time and at a respective uniform rate. The computer also controls associated switching valves via an interface device and may be a desk top machine with keyboard or pre-programmed data input.
