The invention provides a method for generating an n dimensional vector as a shape descriptor of a model, and corresponding apparatus and shape descriptor. The method comprises: determining a type element of the vector to describe the basic shape of the model; and calculating n−1 metric elements of the vector, each of which represents the percentage of all of a feature of the model falling into one of n−1 layers divided as a function of the type element.

Many 3D mesh models have a large number of small connected components that are repeated in various positions, scales and orientations. The respective positions are defined by the position of at least one reference point per component. For an enhanced encoding of the positions of the respective reference points, a given space is divided into segments and the number of points lying in each particular segment is determined. When a cell with at least n points is subdivided into child cells, an indication is added indicating if all points of a parent are in only one child cell. If so, the index of the only non-empty child node is encoded, while otherwise the number of points in one of the two child cells is decremented and encoded. The invention avoids non-effective subdivisions of a cell, and therefore improves the compression efficiency.

A method of fabricating a shallow trench isolation structure is described. A mask layer is formed on a substrate. The mask layer and the substrate are patterned to form a trench in the substrate. A first deposition step and a second deposition step are performed to form a first isolation layer over the substrate. A third deposition step is performed to form a second isolation layer on the first isolation layer. The second isolation layer has a greater fluidity than the first isolation layer has. A planarization process is performed with the mask layer serving as a stop layer. A portion of the first isolation layer and the mask layer are removed to form the shallow trench isolation structure.

A light emitting diode package structure includes a substrate, LED bare chips and a lens. The substrate has an upper surface, a lower surface and a side surface between the upper surface and the lower surface. The upper surface is provided with a circuit pattern. The side surface is provided with a groove. The LED bare chips are fixed on the upper surface and electrically connected with the circuit pattern. The lens covers the LED bare chips, the upper surface and the circuit pattern by an injection molding process so as to be inserted into the groove. With this arrangement, the connecting strength between the substrate and the lens can be enhanced, thereby achieving waterproof and anti-electrostatic effects. Further, material cost of the present invention is reduced greatly.
