Did I make mistake in typing "inorganic"? No, it is true. Spin techlogy is usually regarded as a cheap method to deposite organic material because organic material can be dissovled in popular solvent. Si based inorganic semiconductor is covalent bond, and it has very low slubility in virtually any solvent. However, some inorganic material such as chalcoginide has relatively weak bond compared with Si. IBM's T.J. Watson Resaerch Center has discovered that this type of material may be dissolved in solvent hydrazine (N2H4) with other adding chemical. for example, Sn(S)y(Se)x can be dissovleved when extra solfur is added. The solution then is spin on substrated. After baking, the solvent and extra sulfur is evaporated. This results in very thin semiconductor Sn(S)y(Se)x.

Memory sure is becoming cheaper these days. I'm curious as to when we will eventually reach the rate of 1c to 1 GB.
I can't wait for the day when I will finally be able to afford a 20 TB harddisk, lol. But for now I will be happy with having a 32 gig Micro SD in my R4i.
