摘要:
Embodiments herein describe techniques for forming multiple cut regions with orthogonal corners on multiple fins of a semiconductor device based on multiple masks formed by using sacrificial layers with embedded grating lines. A cut region with orthogonal corners on a fin may be formed based on a mask with the aid of the grating lines embedded within a sacrificial layer, where the irregular shape of the mask may land on the grating lines without affecting the cut region formed on the fin. Multiple cut regions formed by multiple masks may be accumulated on a sacrificial layer, which may act as an intermediate patterning layer. Multiple cut regions with orthogonal corners on multiple fins may be formed in a single pass based on the multiple cut regions accumulated on the intermediate patterning layer. Other embodiments may also be described and claimed.

Pour obtenir un film en un premier matériau sur un support en polymère : on colle une première plaque sur une seconde plaque (2), l'une au moins de ces plaques comportant au moins une couche du premier matériau située à proximité de l'interface, on creuse dans la première plaque au moins une cavité (4) dont le fond (5), parallèle à l'interface entre les première et seconde plaques, définit dans la première plaque une zone de fond, on forme une couche de polymère (8) dans cette cavité sur une épaisseur contrôlée à partir de son fond, on élimine la seconde plaque sur au moins la majeure partie de son épaisseur, en sorte de libérer, sous la couche de polymère, un film comportant ladite couche du premier matériau.
摘要:
The present invention relates to a method for preparing a substrate (1) with the purpose of detaching a layer, called the detachment layer, from said substrate by irradiation of the substrate with a light flux (F) for heating a buried region of the substrate and bringing about decomposition of the material of that region to detach said detachment layer, characterized by the fact that it comprises the steps consisting of: a) fabricating an intermediate substrate including a first layer (2), called the buried layer, and a second layer (4), called the covering layer, covering all or part of the first layer (2), - the covering layer (4) being substantially transparent to said light flux (F), - the buried layer (2), formed by implantation of particles into the substrate, absorbing said flux (F) for its part, b) selectively and adiabatically irradiating a region, called the treated region, of the buried layer (2) until at least partial decomposition of the material constituting it ensues.

The present invention relates a method for the formation of an at least partially relaxed strained material layer, the method comprising the steps of providing a seed substrate; patterning the seed substrate; growing a strained material layer on the patterned seed substrate; transferring the strained material layer from the patterned seed substrate to an intermediate substrate; and at least partially relaxing the strained material layer by a heat treatment.
