Semiconductor devices, such as vertical-cavity surface-emitting lasers, and methods for manufacturing the same, are disclosed. The semiconductor devices include contact extensions and electrically conductive adhesive material, such as fusible metal alloys or electrically conductive composites. In some instances, the semiconductor devices further include structured contacts. These components enable the production of semiconductor devices having minimal distortion. For example, arrays of vertical-cavity surface-emitting lasers can be produced exhibiting little to no bowing. Semiconductor devices having minimal distortion exhibit enhanced performance in some instances.

Semiconductor devices and methods for producing the same

A multilayer interconnect is described which enables electrically connecting a complex distribution of VCSEL or other light emitter elements in a large high density addressable array. The arrays can include many groups of VCSEL elements interspersed among each other to form a structured array. Each group can be connected to a contact pad so that each group of light emitter elements can be activated separately.

Ohmic contacts, including materials and processes for forming n-type ohmic contacts on n-type semiconductor substrates at low temperatures, are disclosed. Materials include reactant layers, n-type dopant layers, capping layers, and in some instances, adhesion layers. The capping layers can include metal layers and diffusion barrier layers. Ohmic contacts can be formed on n-type semiconductor substrates at temperatures between 150 and 250&#xb0; C., and can resist degradation during operation.
