摘要:
A semiconductor element is formed in a mesa portion of a semiconductor substrate. A cavity is formed in a working surface of the semiconductor substrate. The semiconductor substrate is brought in contact with a glass piece made of a glass material and having a protrusion. The glass piece and the semiconductor substrate are arranged such that the protrusion extends into the cavity. The glass piece is bonded to the semiconductor substrate. The glass piece is in-situ bonded to the semiconductor substrate by pressing the glass piece against the semiconductor substrate. During the pressing a temperature of the glass piece exceeds a glass transition temperature and the temperature and a force exerted on the glass piece are controlled to fluidify the glass material and after re-solidifying the protrusion completely fills the cavity.

A source material, which is based on a glass, is arranged on a working surface of a mold substrate. The mold substrate is made of a single-crystalline material. A cavity is formed in the working surface. The source material is pressed against the mold substrate. During pressing a temperature of the source material and a force exerted on the source material are controlled to fluidify source material. The fluidified source material flows into the cavity. Re-solidified source material forms a glass piece with a protrusion extending into the cavity. After re-solidifying, the glass piece may be bonded to the mold substrate. On the glass piece, protrusions and cavities can be formed with slope angles less than 80 degrees, with different slope angles, with different depths and widths of 10 micrometers and more.

A substrate protective film composed of chromium metal is formed on a molding surface of a mold base material composed of cemented carbide. The substrate protective film is oxidized by heat treatment or ion implantation, so that a surface protective film composed of chromium oxide is formed. A pair of molds having such a constitution are prepared. Softened glass is pressed between the surface protective films of the paired molds, so that optical glass elements are molded.

An axial symmetric molding glass lens has a central longitudinal axis, a lens surface, an annular intermediate area and a mounting flange area. The lens surface is axial symmetric around the central longitudinal axis and is curved. The annular intermediate area is curved and axial symmetric, is formed around the lens surface and has a radius of curvature having a continuously vary modulus that decreases as the radius of curvature approaches the annular intermediate area. The mounting flange area is formed around and connects smoothly to the annular intermediate area. The axial symmetric molding glass lens has fine precision, a high production rate and a low cost.

A composite mold includes a porous mold base and a lubricant filled in the porous mold base. The porous mold base includes at least a first portion, which includes a sintered material formed by sintering noble metal particles and tungsten carbide particles. A molding surface of the porous mold base is defined on the first portion. Preferably, the porous mold base further includes a second portion. The second portion of the mold base is integrally formed with the first portion, and is located distal from the molding surface. The second portion of the mold base is made of a sintered material formed by sintering tungsten carbide particles. Alternatively, the second portion, like the first portion, is made of a sintered material formed by sintering noble metal particles and tungsten carbide particles. A method for making a composite mold is also provided.
