The present disclosures relates to a method for producing ultrathin chip stacks and chip stacks. The ferroelectric capacitor includes a word line perpendicular electrode as a first electrode and a storage perpendicular electrode as a second electrode apart at a predetermined interval from the word line perpendicular electrode to have a column type, where a ferroelectric material is filled in a space where the first electrode are separated from the second electrode. The invoice tracking module transfers a PO number to a purchasing module. In most embodiments, the binder comprises 25% or less, by weight, of the product, resulting in a product that is less sweet than other grain-based handheld food products, yet retains a chewy texture.
