An isolation system and method are disclosed. The isolation system includes a beam that includes a first end and a second end. The isolation system may include at least one clamping block comprising first elastomeric material, and the first end may be coupled with the first elastomeric material by the at least one clamping block. An end condition of the buckling beam may be varied based on compression stiffening of the first elastomeric material.

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.

A method of testing a SMA element includes connecting the SMA element to a validation tool, and applying an electrical current to the SMA element over a test cycle. A resistance of the SMA element during the test cycle is measured, while the electrical current is being applied. The measured resistance of the SMA element during the test cycle is correlated to an estimated strain value of the SMA element during the test cycle. A temperature of the SMA element during the test cycle is estimated. A stress in the SMA element during the test cycle is estimated from a stress predicting grid, using the estimated strain value and the estimated temperature of the SMA element during the test cycle. The proper functionality of the SMA element may be determined based on the estimated stress in the SMA element.

Techniques for fabricating a semiconductor chip having a curved surface include placing a substantially flat photonic sensor chip on a recessed surface of a mold such that an active region of the photonic sensor chip at least partially covers a concave central region of the mold and an inactive region of the photonic sensor chip at least partially covers a convex peripheral region of the mold. The mold has a radially varying curvature and the recessed surface includes the concave central region and the convex peripheral region concentrically surrounding the concave central region. Pressure may be applied on the photonic sensor chip to press and bend the photonic sensor chip into the mold.

Techniques for fabricating a semiconductor die having a curved surface can include placing a substantially flat semiconductor die in a recess surface of a concave mold such that corners or edges of the semiconductor die are unconstrained or are the only portions of the semiconductor die in physical contact with the concave mold. The semiconductor die can include through-die cut lines that can lead to substantially less tension in the semiconductor die as compared to the case where the semiconductor die does not include through-die cut lines. Accordingly, such through-die cut lines can allow for achieving relatively large curvatures.
