Title: Semiconductor device
Inventor: MIURA TAKAO
IPC: H01L21/76
Filed: 1987-12-17
Abstract: PURPOSE:To realize element isolation structure preventing the formation of a channel without shaping a channel cut region having high impurity concentration by forming a space charge layer having one symbol into an insulating layer on the surface of a semiconductor base body and including a region in which charges having a reverse symbol are induced in a region being in contact with the insulating layer in the base body by the space charge layer. CONSTITUTION:A field oxide film 2 is formed onto a P-type silicon base body 1 through a selective oxidation means using an silicon nitride (Si3N4) film 10 as an oxidation-resistant mask film, and the base body 1 is dipped into the aqueous solution of polyaluminum chloride, etc. Consequently, Al atoms 11 adhere on the surfaces of the Si3N4 film 10 and the oxide film 2. A polysilicon layer 12 is shaped onto the base body through a CVD method, and heated. Al atoms 11 adhering on the surface of the oxide film 2 deeply diffuse by the heating, and a space charge layer 3 having negative (-) charges is formed in a region near the bottom of the field oxide film 2. A positive (+) charge induction region 4 functioning as a channel cut region is shaped to the surface section of the base body 1 being in contact with the field oxide film 2. The polysilicon film 12, the Si3N4 film 10 and an underlay oxide film 9 are removed, thus completing LOCOS isolation structure.

Filed: 1990-11-27
Abstract: PURPOSE:To obtain a reproduced wave form of a reduced wave form distortion by specifying the values at the light absorptivity and the heat value of a wavelength of a recording light at a light absorbing layer absorbing the recording light provided on a substrate. CONSTITUTION:While the optical information recording medium 1 forming a pregroove is rotated, a laser spot L1 modulated to the signal in accordance with a CD standard is irradiated on the light absorbing layer 3 from the substrate 2 side with a pickup. Hence the light absorbing layer 3 generates heat and the substrate 2 is deformed with the heat to form a pit 11. At this time if a dye in the light absorbing layer 3 is less than 40% at a light absorptivity of a wavelength of the recording laser light, the reflectance can be 70%. Also if the heat value is less than 300 cal per/g, a temporary heat value due to the energy absorption of the laser light can be balanced with a secondary heat value causing dye decomposition with this heat so that the shape of the pit is clear and the reproduced signal is clear.
