Lightwave diffraction device formed of a dielectric layer (4), a mirror (12) arranged at the lower face (10) of said layer, a semi-reflective structure (13) arranged at the upper face (100) of said layer, and a diffractive structure (8) arranged in said layer or on its faces. The height (H) of the layer is chosen so as to substantially satisfy the resonance condition for at least one leaky mode propagating in said layer for at least one given incident wave having a determined wavelengthλ and a determined incidence angle θ_c. Next, the diffractive structure is arranged so that there is no propagating positive diffracted order, and so that all negative orders other than the −1^st propagating order have zero or a relatively small diffraction efficiency, the reflected −1^st order propagating in a direction non-parallel to the incident wave. This diffraction device allows a high diffraction efficiency of up to 100% for the −1^st order.

An LED chip of the present invention has a structure in which an n-type semiconductor layer and a p-type semiconductor layer are successively formed on the lower face of an element substrate, with the p-type semiconductor layer being formed on an area except for an area for an n-electrode. A first n-electrode is formed on the area for the n-electrode and a first p-electrode is formed on the p-type semiconductor layer. A first insulating layer having openings and is formed on the first n-electrode and the first p-electrode, and a second n-electrode and a second p-electrode having virtually the same size are formed on the first insulating layer. With this arrangement, the electrode on the n-type semiconductor layer can be made larger, thereby a mounting process of LED chips onto a circuit board can be executed by using solder at low costs.

A retaining wall block system having multiple sizes and shapes of blocks with differently dimensioned, interchangeable front and back faces. The blocks are used to construct an irregularly textured wall having a weathered, natural appearance. Multiple channels in the lower face of the block are used to engage pins in pin-receiving apertures to form an attachment system. Horizontal reinforcing members are also used in the channels and vertical reinforcing members are used in cores of adjacent blocks for reinforcing a wall. Reinforcing geosynthetic materials can also be firmly held in a wall by means of the pins or by connectors adapted to fit in the block channels.

Process for the production of a sealing and mechanical strength ring between a substrate and a chip hybridized by bumps on the substrate. The invention provides a process for producing an encapsulating ring (13) ensuring the sealing and mechanical strength of a chip (1) hybridized by bumps on a substrate (5). More particularly, contemporaneously with the production of the hybridization bumps (9) on the lower face (1a) of the chip or the substrate by a first meltable material, a sealing and mechanical strength ring is formed by depositing on the substrate or lower face of the electronic component a ring (13) of a second meltable material. The lower face of the chip then is placed on the substrate so as to produce the connections between said chip and said substrate by means of the first meltable material, and the thus formed assembly is heated to a temperature at least equal to the highest melting point of the first and second meltable materials, in order simultaneously to produce the hybridization bumps of the first material and the sealing ring of the second material. The ring is sized to have a height (h) and a width (d) in accordance with the following equation:in which alpha is a shape coefficient factor and D is the largest dimension of the electronic component.
