Title: Heating cooker
Inventor: KAWAKATSU AKIRA
IPC: H05B3/10
Filed: 1987-04-28
Abstract: PURPOSE:To improve thermal efficiency and remove the difference in thermal efficiency in spite of variation in the material quality and the surface condition of a cooker by forming a supporting plate of a crystallized glass which shuts off light in a near infrared ray region while radiating light in a far infrared ray region. CONSTITUTION:A supporting plate 8 consists of a crystallized glass which shuts off light in a near infrared ray region while radiating light in a far infrared ray region. That is, the infrared rays in a near infrared ray region heading for a cooker 20 from an infrared ray lamp 10 is shut off by a supporting plate 8. The shut-off near infrared rays heat the supporting plate 8 so that the supporting plate 8 itself radiates light in the far infrared region. Accordingly, the cooker 20 is heated mainly by the far infrared rays radiated from the supporting plate 8 so that a commonly-used cooker has good absorption of the far infrared rays. Thereby, thermal efficiency is generally improved, with a small difference in an absorption rate according to materials thus removing difference in thermal efficiency in spite of variation in the material quality the surface condition or the shape of the cooker.

Abstract: PURPOSE:To prevent occurrence of cracks due to the needle pressure of a metallic probe at the time of characteristic inspection and short circuits between a bonding pad and a semiconductor substrate and to enhance the yield rate of products and reliability, by forming an insulating protecting film at a part separated from the bonding pad. CONSTITUTION:An insulating protecting film 1 comprising an oxide film and a nitride film is formed on a metallic film at a part separated by a distance (d). It is desirable that the distance (d) is slightly larger than the diameter of the tip of a metallic probe, which is contacted with a the bonding pad 2 in the inspecting process of a semiconductor device. Even if the metallic probe of a prober is positioned on the bonding pad 2 and slipped laterally in the inspecting process of the semiconductor device, the tip of the metallic probe is stopped at a side wall 6 of the insulating protecting film 1, which is separated from the bonding pad 2. Therefore, even if cracks occur in an insulating film 3 beneath the stopped position, the short circuit between the bonding pad 2 and a semiconductor substrate 4 is avoided by migration, which is yielded in the bonding pad 2.
