A method of forming a curved semiconductor includes: forming a device layer on a semiconductor substrate; forming a metal layer on the device layer; removing the semiconductor substrate from the device layer; and curving the device layer and the metal layer.

Curved semiconductor and method of forming the same

A method of manufacturing a hybrid focal-plane array includes: forming a read-out integrated circuit with integral bending slit; forming a detector die separately from the read-out integrated circuit and including a detector with integral bending slit; and joining the read-out integrated circuit and the detector die to each other such that the read-out bending slit and the detector bending slit are aligned with each other.

Hybrid focal-plane array and method of manufacturing the same

A method of manufacturing a curved semiconductor die includes: designing a semiconductor die design by conducting finite element analysis of an initial semiconductor die design having a partial spherical curvature, the initial semiconductor die design including a shape of a semiconductor die and a location and shape of a slit in the semiconductor die; when a size of a gap at the slit in the curved semiconductor die is outside a tolerance, modifying the initial semiconductor die design to provide a revised semiconductor die design and conducting another finite element analysis thereof; when the size of the gap at the slit in the curved semiconductor die is within the tolerance, manufacturing a microfabrication mask utilizing the initial semiconductor die design or the revised semiconductor die design having the size of the gap within the tolerance; forming a semiconductor die by utilizing the microfabrication mask; and curving the semiconductor die.
