摘要:
An equipment for manufacturing semiconductor devices, comprises a processing tool which processes a to-be-processed surface of a semiconductor workpiece to a target shape, a monitor which three-dimensionally monitors a shape of a processed surface of the semiconductor workpiece while the semiconductor workpiece is set in the processing tool, and a controller which controls the processing tool in a feedback manner on the basis of the shape of the processed surface monitored by the monitor. If the shape of the processed surface deviates from the target shape, the controller adjusts process conditions of the processing tool so that the target shape can be obtained.

An electrically conductive mask having openings formed is located above a semiconductor substrate and ions are implanted into the surface of the semiconductor substrate through the electrically conductive mask, thereby forming ion implanted layers. For ion implantation under different conditions, a dedicated electrically conductive mask is used wit each ion implantation step.

A heating method for heating an object by making use of a heating apparatus comprising lamps and light transmissive columnar bodies each being positioned in front of and in the light irradiating direction of each of the lamps and having a fore-end constituting a light-receiving face for taking up an irradiated light from the lamp and a rear-end constituting a light-irradiating face for irradiating light; the object being disposed to face the light-irradiating faces of the light transmissive columnar bodies and heated by the irradiation of light transmitted via the light transmissive columnar bodies from the lamps. A distance between the light-irradiating faces of the light transmissive columnar bodies and the object is set to around 0.3L or not less than 0.8L (herein, L is a width of the light-irradiating face).
摘要:
A method of maintaining cleanliness of substrates including a first step for accommodating at least a piece of substrate having a gaseous impurity-trapping filter arranged close thereto in a hermetically sealed box, and a second step for circulating the atmosphere in the box at a rate of two or more times a minute so that impurities in the atmosphere are adsorbed by the gaseous impurity-trapping filter. A box for accommodating substrates includes a housing in which space for accommodating the substrates is hermetically closed with a lid, a gaseous impurity-trapping filter arranged in the housing and adapted to adsorb impurities contained in the atmosphere in space, and an atmosphere-circulating device having a ratio of the circulating capacity to the space volume of not smaller than 2 in order to circulate the atmosphere so as to pass it through the gaseous impurity-trapping filter.
摘要:
The purpose of the present invention is to avoid a decrease in the mechanical strength of a Si substrate because of the repetition of ion-implantation and annealing processes. As ions are implanted while the Si substrate surface temperature is kept at as low as −60° C. or less. Then the Si substrate is heated to recover the implantation defects caused by the ion-implantation. Such a combination of the low temperature ion-implantation and the annealing processes is repeated as required.
