Abstract:
PROBLEM TO BE SOLVED: To easily form a circuit member at an upper position of a cavity buried in a substrate, on the substrate of an integrated electronic circuit. SOLUTION: The upper part of the cavity C formed in the substrate 100 of the integrated electronic circuit is closed, and a hollow E is formed. The hollow E is buried by a material 10 selected so that reflection of a lithography radiation F1 may be weakened. If the radiation is irradiated after a resist layer 3 is laminated on the circuit, a portion positioned at the upper part of the hollow E of the resist layer 3 is exposed to a dosage which is lower than a threshold of development of a resist only by primary flux F1. A portion outside the hollow of the resist layer 3 is exposed to the higher dosage than the threshold, by the primary flux F1 and secondary flux F2 reflected from a surface of the substrate 100. When the resist layer 3 is developed, a mask M2 is obtained only at the upper part of the cavity C. COPYRIGHT: (C)2007,JPO&INPIT

Abstract:
A surface of a substrate (2) comprising microcavities (1) leading out of the substrate is placed in contact with an aqueous solution comprising a plurality of suspended particles (4) and a fabric (3). Perpendicular pressure is applied the expanse of the substrate (2) between the fabric (3) and the surface of the substrate (2), and relative movement of the fabric (3) and the surface is applied to the expanse of the substrate. At least one particle (4) is thus fed into each microcavity (1), therein forming a porous material that is a catalyst material for nanothread or nanotube growth.
Abstract:
The present invention relates to a method for position-controlled fabrication of a semiconductor quantum dot, the method comprising: providing a substrate (102) of a substrate material; depositing a sacrificial layer (108) of a sacrificial material; depositing an active layer (110) of a semiconductive active material on the sacrificial layer, wherein the substrate, sacrificial and active materials are chosen such that the sacrificial layer is selectively removable with respect to the substrate and the active layer, depositing and patterning a mask layer on the active layer so as to define desired quantum-dot positions in lateral directions, fabricating a lateral access to the sacrificial layer in regions underneath the patterned mask layer; selectively removing, with respect to the substrate and the active layer, the sacrificial layer from underneath the active layer at least under the patterned mask layer; and etching the active layer under the patterned mask layer from underneath the active layer so as to assume a desired quantum-dot shape.
Abstract:
A method for manufacturing a semiconductor device includes providing a patterned hard- mask layer (41). The hard-mask layer (41) is provided on an exposed surface (16) of one or more layers to be patterned of a semiconductor intermediate product (1). The hard-mask layer (41) covers the exposed surface (16) in covered areas (46) of the one or more layers to be patterned and does not cover the exposed surface (16) in bared areas (47) of the one or more layers to be patterned. One or more recesses (17,48,50) are formed in the layers to be patterned by at least partially removing the layers to be patterned in the bared areas (47). The hard-mask layer (41) is ten removed. After removing the hard-mask layer (41) the recess (17,48,50) is filled with a filling material (31,32).

The present invention relates to a test structure that comprises at least two devices under test DUT, which respectively have a first electrical device resistance in a non- defect state and a second electrical device resistance in defect state, the first being higher than the second electrical device resistance. In the test structure the DUTs are connected in parallel to a first test contact pad via a first conducting line and connected in parallel to a second test contact pad via a second conducting line, and respectively connected to the first conducting line via respective first test resistors, which have known respective electrical test resistances, such that a total electrical resistance between the first an second test contact pads is indicative of the number of DUTs, which have the second electrical device resistance. The test structure allows testing a larger number of DUTs in parallel in a single measurement.
