Abstract: PURPOSE:To prevent the generation of a surface defect, and to reduce leakage currents by growing an epitaxial layer on a substrate and thermally treating the whole according to a predetermined method. CONSTITUTION:An epitaxial layer 2 having the same conduction type as a semiconductor substrate 1 is grown on the semiconductor substrate 1 in 10-20mum.

Title: Integrated circuit device and manufacture thereof
Inventor: TSUCHIYA KAZUHISA
IPC: H01L27/08
Filed: 1990-03-07
Abstract: PURPOSE:To increase a junction breakdown strength of an impurity diffusion region by a method wherein the impurity diffusion region is not joined directly to an impurity region for channel stopper use but is joined to a comparatively- low-concentration impurity region. CONSTITUTION:A width of a comparatively-high-concentration impurity region 21 for channel stopper use which has been formed at the lower part of a field oxide film 3 is narrowed; low-concentration regions 23 are formed between the region and diffusion regions 9. Consequently, a threshold voltage of a field parasitic transistor which is formed of a conductive layer 7 formed of polycrystalline silicon or the like, the field oxide film 3 and the individual diffusion layers 9 is kept high because the high-concentration region 21 for channel stopper use exists. Since low-concentration regions of a width (d) exist between the high-concentration region 21 and the diffusion regions 9, the diffusion layers 9 are not joined directly to a high-concentration ion implantation region. Thereby, a junction breakdown strength, e.g. between the N<+> type diffusion layers 9 and other regions of a P-type substrate can be increased.

Filed: 1997-02-25
Abstract: PROBLEM TO BE SOLVED: To prevent an unauthorized copying by satisfactorily identifying the unauthorized copying and also to cope with the prevention with a simplified equipment and moreover to maintain compatibility also. SOLUTION: The margin part 20 and the disk management part 22 of a read-in area 12 are respectively constituted of excessive sectors M1, M2 and sectors LI1, LI2. The number of the excessive sectors is set to a very small number of the order of numbers which do not violate a standard and is made to be sectors having two numbers of 'n', 'n+1'. When a disk having this sector constitution is copied with a normal disk recording device, the number of excessive sectors is increased by two and sectors M4, M3, M1, M2 whose numbers are 'n-2', 'n-1', 'n', 'n+1' become excessive sectors. Thus, it is made possible to identify whether a disk is a regular disk or an unorthorized disk from the change of the number of the excessive sectors.
