ABSTRACTA new laser recrystallizing technique has been developedfor high density SOI-LSI's. This technique produces single crystalline silicon islands on an amorphous insulating layerwithout seed. Square windows are opened at arbitrary places in an antireflection cap over a polycrystalline film on an amorphous insulatinq layer. Grain boundaries of the polycrystalline Si in the window are removed completely at the subsequent laser-recrystallization step. Single crystalline silicon islands are formed by self-aligned etching of silicon film which was covered by the antireflection cap. This technique is an effective method for fabricating high density SOI-LSI's, since the singlecrystalline islands can be fabricated at arbitrarily selected places. Yield of the grain-boundary-free islands was 95% the size of the island is 1O x 20μm, and the irradiation oyerlap of laser-beam traces is 70%.

AbstractTensile tests on notched plates of single-crystalline silicon were carried out at high overloads. Cracks were forced to propagate on {110} planes in a <110> direction. The dynamics of the fracture process was measured using the potential drop technique and correlated with the fracture surface morphology. Crack propagation velocity did not exceed a terminal velocity of v = 3800 m/s, which corresponds to 83%7 of the Rayleigh wave velocity vR. Specimens fractured at low stresses exhibited crystallographic cleavage whereas a transition from mirror-like smooth regions to rougher hackle zones was observed in case of the specimens fractured at high stresses. Inspection of the mirror zone at high magnification revealed a deviation of the {110} plane onto {111} crystallographic facets.
