Low temperature process for laser dehydrogenation and crystallization of amorphous silicon
TL;DR: In this article, a low temperature process for dehydrogenating amorphous silicon using lasers is described, where irradiation at the various energy densities can result in the formation of polysilicon due to melting of the ammorphous silicon layer.
Patent
Buffered substrate for semiconductor devices
TL;DR: In this article, a buffered substrate consisting of a substrate, a buffer layer and a silicon layer is constructed by crystallizing a polycrystalline silicon layer using a laser beam and the buffer layer is disposed between the substrate and the silicon layer.

TL;DR: In this paper, the authors used polycrystalline lead iodide as a thick semiconductor detector on an active matrix flat panel array for x-ray imaging with a test image sensor with 100 micron pixel size.
Patent
Method of manufacturing a thin film transistor with reduced parasitic capacitance and reduced feed-through voltage
TL;DR: In this paper, a method of producing an improved thin film transistor structure having no source/gate or drain/gate overlap is provided, where a radiation filter is employed, which is transparent to light at the photolithography wavelength but reflective or opaque at the laser wavelength.
Patent
Continuous amorphous silicon layer sensors using doped poly-silicon back contact
TL;DR: In this article, a method and apparatus for reducing vertical leakage current in a high fill factor sensor array is described, which is achieved by eliminating Schottky junction interfaces that occur between metal back contacts and intrinsic amorphous silicon layers.
