A portable computer laptop desk is provided when attached to a structure that in turn is supported on web strapping that passes over the upper legs of the operator when in the seated position. The strapping is attached to foldable and telescopable side and center supports for the structure that slide into and fold over the structure forming a package comparable in size to the portable computer.

A precise thickness bulk etchable wafer material, that is responsive to protection with an oxide that inhibits insertion of an etch responsiveness altering material, is assembled with a membrane material that is susceptible to deposition processes. A bulk etch then removes most of the wafer. The arrangement permits the strength and rigidity of the bulk spacer to serve to permit the finely controllable deposition processes for ultra thin and wider ranges of membrane materials, the selective protection for spacer shaping and finally, the removal by the low stress process of etching, of the unused bulk spacer material. An oxide layer is patterned on a bulk spacer material wafer that has a thickness of the gap between an X-ray mask and the to be patterned oxide. The oxide on the bulk spacer material prevents conversion, through the exposed surface of the bulk spacer material wafer, of a portion of the wafer that is to serve as the spacer to a different etch responsiveness from that of the bulk spacer material. The exposed bulk spacer material wafer is converted to a depth that will serve as the spacer and to protect the edges. The oxide is then removed. The membrane is deposited over the full surface of the bulk spacer material. The bulk wafer is removed down to the converted portion using the imparted different etch responsivness.

Three component color sub-pixel element areas of red,green and blue, are serially formed in an overall pixel area, on a transparent substrate, and after each individual color sub pixel element formation, a layer of protective transparent material is applied over the individual sub pixel element and the pixel area before formation of the next sub pixel element. The protective layers render the sub pixel elements unaffected by the processing of subsequent sub pixel members where such conditions as high temperature curing, hardening agents or hardening processes are involved, whereby advantages are achieved in manufacturability, reliability, yield, cost, and throughput.
