    Abstract: A method for fabricating light emitting diode (LED) dice includes the steps of: providing a substrate, and forming a plurality of die sized semiconductor structures on the substrate. The method also includes the steps of providing a receiving plate having an elastomeric polymer layer, placing the substrate and the receiving plate in physical contact with an adhesive force applied by the elastomeric polymer layer, and performing a laser lift-off (LLO) process by directing a uniform laser beam through the substrate to the semiconductor layer at an interface with the substrate to lift off the semiconductor structures onto the elastomeric polymer layer. During the laser lift-off (LLO) process the elastomeric polymer layer functions as a shock absorber to reduce momentum transfer, and as an adhesive surface to hold the semiconductor structures in place on the receiving plate.

    Abstract: According to a certain embodiment, a pin plunger includes: a first contact member; a second contact member that faces the first contact member and is apart from the first contact member; a spring arranged between the first contact member and the second contact member; and a housing that houses the first contact member, the second contact member, and the spring. The housing comprises a bimetal inside or outside the housing. The bimetal comprises a first metal and a second metal, the first metal having a thermal expansion coefficient different from a thermal expansion coefficient of the second metal. The elastic force decreased or increased by contracting or expanding of the spring due to a temperature change is compensated with a warping force due to stretching of the first metal and the second metal.
