Rearview Mirror Assemblies With Anisotropic Polymer Laminates

Anisotropic film laminates for use in image-preserving reflectors such as rearview automotive mirror assemblies, and related methods of fabrication. A film may comprise an anisotropic layer such as a light-polarizing layer and other functional layers. The film having controlled water content is heated under omnidirectional pressure and vacuum to a temperature substantially equal to or above a lower limit of a glass-transition temperature range of the film so as to be laminated to a substrate. The laminate is configured as part of a mirror structure so as to increase contrast of light produced by a light source positioned behind the mirror structure and transmitted through the mirror structure towards a viewer. The mirror structure is devoid of any extended distortion and is characterized by SW and LW values less than 3, more preferably less than 2, and most preferably less than 1.

Methods of producing a heterogeneous semiconductor structure

The present invention relates to a method for forming a heterogeneous assembly of first and second materials having different coefficients of thermal expansion. The method includes bonding a surface of a first substrate of a first material to a surface of a second substrate of a second material wherein the first substrate includes a zone of weakness therein to define a transfer layer adjacent the first surface, providing a stiffening substrate of a third material to maintain sufficient flatness and prevent breakage of the transfer layer during detachment from the first substrate, and detaching the transfer layer from the first substrate along the zone of weakness to form a heterogeneous assembly of the transfer layer and second substrate. The stiffening substrate is bonded to one of the first or second substrates and the third material has a coefficient of thermal expansion that is the same as or close to that of the material of the substrate to which the stiffening substrate is bonded to facilitate a successful detachment of the transfer layer from the first substrate.
