Inventor: KANNER ROWLAND W
IPC: A61B17/11
Filed: 2004-02-20
Abstract: A tissue punch which is configured to operate by utilizing a spring force to compress tissue between a rotatable cutter blade and a tissue piercing element. The tissue punch is configured such that once the spring force is applied, the cutter blade can be selectively rotated by the user. The rotation of the blade, assisted by the compression from the spring force, causes the cutter blade to cut through the tissue.

Title: Nitride semiconductor substrate and method of producing same
Inventor: NAKAYAMA MASAHIRO
IPC: H01L21/205
Filed: 2004-09-09
Abstract: A nitride semiconductor substrate having a rugged surface being lapped by whetting granules to roughness between Rms5nm and Rms200nm, which has a function of reducing dislocations of a GaN, InGaN or AIGaN layer epitaxially grown on the lapped substrate by gathering dislocations in the epi-layer to boundaries of holes, pulling the dislocations to bottoms of the holes. Higher roughness of the nitride substrate degrades morphology of an epitaxially-grown layer thereon but reduces dislocation density to a lower level. Morphology of the epi-layer contradicts the dislocation density of the epi-layer. The nitride semiconductor substrate can reduce dislocation density and can be low cost and useful substrates.
