Laptop sales are hurting mostly due to an ongoing shortage of processors from Intel. This has become a sore point for the whole industry as manufacturers globally are affected.
Intel has had their 14nm lines running 24/7 making hardware but there is not enough to go around. Demand for server processors has been a problem and the 10nm woes have not been very -pleasing.
Intel recently suggested 10nm hardware will start trickling in the fall. Its not likely to be nearly enough for the laptop sector’s needs. Most likely the laptop market and tablet market will have to wait until 2021 when adequate supplies of processors finally become available.
Evidently there are still not enough foundries around the world to handle mobile needs. Mobile phones need a CPU, RAM and flash memory.
Micron reported RAM sales were slowing which suggests the laptop market downturn is having industry wide effects.
Intel 14nm has a gate length of about 20nm, so attempting to make that smaller has many challenges that are worse than FinFET can manage. Copper resistance rises at smaller sizes so Cobalt has been used but even Cobalt has its shortcomings.
Deep UV and Extreme UV are generally needed to be able to expose a mask without excessive double patterning etc. Synchrotron radiation has been experimented with successfully and it has been considered seriously by the industry.
