| I created Chip Tycoon as an animated visualization of the
| semiconductor manufacturing process, inspired by the classic
| isometric style of RollerCoaster Tycoon and Zoo Tycoon. Rather
| than reading through a long article, you can watch silicon move
| through the major manufacturing stages--from wafer fabrication
| and lithography to packaging and testing--in a miniature factory.
|
| My goal was to make one of the world's most complex manufacturing
| processes easier to understand by turning it into something that
| feels alive and enjoyable to watch.

| It's neat, but I'm not entirely sure what the animations

| needing to be controlled, but this doesn't really have that.
| There's your vehicle moving around, and there's people
| wandering around, but they're not doing anything. It doesn't
| feel like a factory of connected components.

| world where HTML and CSS are practically free to make, we
| might as well spend some tokens on making educational content
| a bit more digestible.
|
| I'm sure there's a plaintext essay that can explain this just
| as well if the RCT style was distracting.

| Some feedback on the UI. Just knowing there was an
| automatic timer made me feel rushed while reading each
| expanded step (regardless of speed selected), so I tried to
| manually take over the navigation, by using the pause
| button, next step button, and tapping factories. This
| caused my conveyor cart to somehow become decoupled from
| the current step and felt kind of buggy.
|
| I also felt trapped in the Loop, which went around 3 times.
| I didn't notice an exit button. Better yet, this is a
| transition where perhaps a swift animation of the cart
| going around a few times on its way to the next step may
| help communicate the sense of repetitiveness you're trying
| to make the user feel.
|
| I was on mobile and I noticed by the end of the park my
| phone had gotten quite noticeably hot - which is unusual
| except when under heavy gaming load.
|
| Thanks for putting this together. Ironically, I found your
| concise and frank little written synopsis at each step the
| most interesting part.

| I had the same feeling. I think it would click more if the
| cart visibly changed after each station -- add a layer,
| change color, get cut into dies, etc.
|
| Then the animation would be doing some of the explaining
| instead of mostly being scenery.

|
| ... what 'Space'? On phone.

| It was AI generated, don't be to demanding ;)
| laurentiurad wrote:
| AI generated or not, the target device was the PC, but the
| point still stands. Anyway, you have a pause button that you
| can click to pause the flow. On PC you might not use the
| mouse that extensively so pressing Space saves time. It's
| just a nitpick that I haven't removed the Space reference on
| mobile, but you can still pause the flow.

| Nice website. One problem, though: the animation goes too fast
| for my reading speed, so I have to click stop. Then when I click
| on the next thing, I have to click stop again. Very annoying. If
| I click stop, just make it stay stopped until I click play again
| (which I won't).
| ed_mercer wrote:
| Same here. You can press space after going to the next building
| as a workaround.

| This is pretty good...simplifies the process and some of the
| items are out of order, but it describes the process pretty well.
|
| Keep in mind, even 20 year old chips have 6-700 steps in their
| process...it's a giant loop of Etch, Photo, Implantation,
| Furnace, Chemical Vapor Deposition, Physical Vapor Deposition,
| Chemical Mechanical Planarization, etc...don't forget the
| measurement steps and defect scans. State of the art chips take
| 3-4 months to complete this process and it's well over a thousand
| steps.

| deposited. (Front End of Line vs Back End of Line). Not to
| mention the lack of diffusion and oxidation. The whole "loop"
| metaphor gives the wrong idea of what's happening.

| All subtly wrong. And no, not in the 'simplified' sense.
