Code:
Blue-violet laser diode for BD recorder
"SLD3234VF" (output 170mW, φ5.6mm)      Apr, 2007  4,500 Yen 
"SLD3234VFI" (output 170mW, φ3.8mm)                5,000 Yen

Blue-violet laser diode for BD player
"SLD3131VF" (output 20mW, φ5.6mm)       Jun, 2007  900 Yen 
"SLD3131VFI" (output 20mW, φ3.8mm)                 1,000 Yen

Blue-violet laser diode for BD recorder
"SLD3235VF" (output 240mW, φ5.6mm)      Nov, 2007  4,500 Yen 
"SLD3235VFI" (output 240mW, φ3.8mm)                5,000 Yen

Since only the player version is needed for the PS3, looks like PS3 production costs are going to drop significantly in June. 900 Yen is about $7.59.

How much are they now?

In iSuppi's teardown, they list the drive as $125. That includes the entire assembly, but diode was probably about 85% of that.

When are they going to 65nm? And they also removed/are removing the PS2 parts

A price drop may actually be feasible on top of being necessary now
 
Thats interesting

so there are potentially $100 savings in th edrive. That coupled with the 65nm chip, sony may be able to drop the price $100 and still see profit.

A ****load. Like ~$100 or so.
Not even close. The high costs associated with the iSupply numbers from last summer were based on industry availability and was still less than $80, and in no way reflected the actual costs of production. Besides, prices don't scale immediately from high to low; it's gradual.

This summer, there was only one fab producing the wafers necessary. Now there are 5 online. Production has ramped up steadily and yields have improved as well. There are frequent small articles in EE Times and other industry sources that report on mild progress, which is continuous.

Add the removal of the Emotion Engine, simpler cooling, plus the lowered manufacturing costs all these changes bring and the savings really start adding up.

It'll help drop the cost of the whole drive, but that is just the laser we are talking about. Which is still a significant drop since it is going from about 50 bucks to 8 bucks to produce.

Maybe. Sony may already be seeing savings now since they make them internally. They certainly weren't doing that at launch though.

65nm should be before the end of the year.

i didn't think a $100 price cut would be possible by the end of the year, but if they really have the Blu-Ray assembly down to < $50, that changes my estimation a lot.

It also does a lot to validate Sony's decision to go with blu-ray in the first place. 50+GB games this gen :D

With the 65nm chip I wonder if we'll see a slightly smaller PS3... well probably not but can always wish.

$400 PS3 seems closer than I thought.

Come on Sony lead the industry to a price cut. It doesn't seem like Microsoft is willing to lead the charge here so it will have to be done by Sony.

The PS3 dropping in price just a year after it was released would be seeing by Sony investors as "IDIOTIC". They just spent hundreds of millions developing the ps3, if they drop the price, it means things at Sony are in a bad way.

Well, remember that the diode isn't the only part. it is the most expensive part because its the main thing that's different from existing DVD drives.

But remember, that Sony went with a really exotic drive assembly. Not only is it slot-loading, its also frigging silent. even with the diode under $10, the whole thing is still probably > $30.

And having consoles sit on store shelves collecting dust because of a $600 price tag won't seem idiotic or a waste of money to Sony investors.

It means they're not ignoring their current situation. They'd be seen as IDIOTIC to continue acting like the situation is A-OK at $600
 
A $200 drop just isn't going to happen this year...it's just not. Even if we take these numbers at face value, Sony's not going to lose an opportunity to make back what they've lost so far on the PS3. A $100 drop is far, far more likely.
 
Supposedly 65nm Cell production has already begun for use in the PS3. A price drop of $100 by the end of the year is definitely in the cards, but if it could drop even more than that then it would definitely bring in a lot more consumers. Of course if that happens then people will say "omg 25% price drop in a year = sony d00med." Hopefully Sony will do good by the early adopters and at least offer them some PSN dollars or vouchers. As a Day 1 buyer, a big price drop wouldn't upset me at all, but it would probably upset some.

they're stuck in catch-22 now. no price drop = they die, price drop = they die

But, again and again, this cost of the diode was mostlyas high as it was because AVAILABILITY was crap, not because of production costs. The opportunity cost to Sony putting it in a PS3 was high because the diode they produced could be sold and put into another company's unit, and that manufacturer would have paid $80-100 for that diode. It didn't cost anywhere NEAR that amount to make. That was the inter-industry OEM cost.

iSupply has to account for market costs, not production cost. There is no way these diodes cost more than $30 to make last summer. Anything higher is crazy and you know nothing about semiconductors. Sure, they are currently using expensive epitaxially grown wafers (that are relatively small). Sure, yields were crap. Still, not that expensive.

Sony, of course, has to recoup (or not) their research investment in the technology, and that has to be accounted for somewhere. But, the actual per-unit costs in the teardown above from iSupply was no where need actual costs to build each individual unit - for the diode and many of the IC devices.

I actually wouldn't be surprised if the per-unit cost of building a blue-wavelength diode today is only 1/2 to 1/3 of what it was this summer.

Is there information to back up these claims? The diode itself wasn't a 100+ dollar part.. it was just a hard to make component since it was new and limited factory production ability.

All thats happened is the diode is mass production doesn't alter drive prices that massive

What do you mean "if they drop the price?" Do you think investors don't already believe the PS3 launch has gone terribly awry?

They were one in the same in this case.

The availability was crap because the failure rate was so high. The production costs of the failed units are folded into the costs of the ones that work.
 
I can't make new threads so I will just post this here: Sony gamers day is on May 14

Some IGN editor or informant posted this

I just heard that a Sony Gamer's Day is being held on May 14th, most-likely to replace their regular May E3 press conference that many developers plan for way in advance.

What do you think we'll see, and do you think we'll see anything new?

I've said it before but I'll say it again:

$399 PS3 + GTA IV November 2007.

Maybe warhawk. I think that's why there's so much confusion on how warhawk is going to be distributed, sony for some reason, doesn't want to say it's gonna be free, packed in with new systems and available to download for everyone else.

a new weak point for Massive damage in the evolution of the giant enemy crab?

I disagree.

1. If the yields can only improve by 30-40%, your only going to save that much by improving your process.

2. There have been no breakthroughs making the epitaxially grown GaN on a crystalline substrate wafers, but there are more people making them so that should reduce buying/production costs a bit. Not at much as you might think. A company has reported a breakthrough producing blue-wavelength diodes on epitaxially grown GaN with a silicon substrate, but I've not read that these are being mass produced yet (new tech and all).

3. Availability wasn't just crap because of low yields; wafer availability was significant.

Bascially, per-unit production costs could not have plummeted - yet. High prices initially reported were mostly based on market demand for the devices. The vast majority of the cost reductions being reported recently is not production improvements, but availability improvements.

The availability improvements are from a gradual ramp up in facilities, gradual ramp up in yields, coupled with lower than expected demand. Per-unit production costs have not fallen that dramatically.
 
Danm E3 would be arriving very shortly... if it wasn't dead.

:(

It seems like it was only yesterday when Sony announced the 599 US DOLLARS.

Do you have any info on the yield for the units Sony is talking about?

I recall reading initial diode yields were in the 10% - 20% range. If they are at 50% now, that would be a 250% - 500% increase.

Oooh oh! A SemiC related thread. :)

I'm still wondering why the fabs are still sticking to GaN to make blue laser diodes. Seriously, they've gotten doped CVD diamond to emit at UV/blue spectrum ages ago and it's not that hard to make. And it's native bandgap is already in the UV range.

They've even gotten it grown epitaxially over sapphire as well, so I don't see what the problem is in making some strained growths over Si or some other substrate.

You won't hear an internal rep quote yields. Ever. There's always speculation by industry observers, but it's pretty much always a trade secret.

Fun story: Micron was doing a presentation on their CCD/CMOS imaging chips and some guy asks "So what's the yield on these chips?" and the presenter laughed and said (paraphrased) "No company would ever reveal their yields!"

edit: Yields seem to always grow exponentially after a certain point. Once fabs start to get about 15% (maybe lower?), they start shipping and continuously tweak the process.

Did you watch the GDC conference?? yeah....

I doubt we will ever see a repeat of the E3 conference from sony
