Abstract:
PROBLEM TO BE SOLVED: To test simultaneously various chips of one substrate with improved economical efficiency. SOLUTION: The invention relates to a method for arranging chips (102-110) of a first substrate (100) on a second substrate (111). In this method, the chips are grouped into at least first chips (102) and second chips (103); the first chips (102) of the first substrate (100) are individualized; and individualized first chips (102) are arranged on the second substrate (111) in agreement, so that each of the first chips (102) is assigned uniquely to the first chips (102), belonging to the first substrate (100) on the second substrate (111).

Abstract:
The invention relates to an electronic switching circuit in which a plurality of test circuit blocks is provided, whereby every test circuit block comprises a first sub-circuit block and at least one second sub-circuit block. A field effect transistor in the first sub-circuit block has a gate insulation layer that is thicker than the gate insulation layer of a field effect transistor in the second sub-circuit block.
Abstract:
The invention relates to a system for connection in integrated MOS structures, wherein various levels and/or elements of a semiconductor chip are interconnected by means of connecting elements. The aim of the invention is to provide a system for connection in MOS structures which, when an affected element causes a high quadrature-axis component of current, allows for a reduction of current conduction or disconnection of the affected element. According to the invention, the connecting elements of the semiconductor chip are arranged and dimensioned in such a manner as to produce electromigration-critical areas by dimensioning a connection of various levels and/or the element in such a manner that electromigration is triggered when the current increases beyond a maximum value.

Abstract:
In the proposed process, a masking layer (L) is deposited on the semiconductor material (1) and structured in the following way: a first region (6) where the contact is located is provided with an aperture (10) with an aspect ratio such that the aspect angle (20) between a diagonal and the normal onto the semiconductor material is less than an angle of incidence (30) onto the masking layer; in a second region where the doped region (7) is located, a ridge (12) of masking layer is left, the doped region being created by oblique implantation of atoms of a first conductivity at an implantation angle equivalent to the angle of incidence (30) and the contact (40) being formed by substantially vertical implantation of atoms of a second conductivity. The invention facilitates implantation of a mask onto a semiconductor well, the source and drain regions of the MOS transistors in the said well, and the contact regions of the complementary well.
Abstract:
Fluorine is deposited on a semiconductor substrate surface according to a novel process. A semiconductor substrate is placed in a reaction chamber and the substrate surface is wetted with water and/or alcohol. A compound containing fluorine is led to the substrate surface, so that a cleaned semiconductor surface covered with fluorine is produced, and the compound containing fluorine is removed from the reaction chamber. The cleaned semiconductor surface covered with fluorine is then wetted with a mixture containing at least 10% by volume of water and at least 10% by volume of alcohol, for producing a cleaned semiconductor surface covered with a predetermined amount of fluorine. The predetermined amount of fluorine is lower the higher a proportion of water in the mixture is chosen to be. Then, the water and the alcohol are removed from the semiconductor surface.
